Want to add a kickstart to your XR650L? Here's how


clc3251

To help out others who want to add a kickstart back up to the electric start on their xr650L I will lay out how I did my conversion and hopefully guide others who want to do the same. First off let me say that everything I did applies to a 1995 XR650L and may not apply to other years, however I don’t see why it wouldn’t.

 

I searched the Internet for an XR650L kickstart conversion and found a few people who said they had added a kickstart, but no one who was willing to share the details. I found a lot of great info on this forum and received tons of help from members, but no one had a list of parts or a guide on how to do it. I amassed as much info as I could and set out to add the kickstart to my XR650L. I found out that the XR600R engine is almost identical to the XR650L with the exception of the kickstart and some gearing. The XL600 is also very close and kickstart parts from both bikes can be used. The kickstart lever and the side cover I used were both from XL600s. I am not sure about the kickstart internals since I bought them from E-bay, but I believe they are the same between both bikes. Fortunately the XR650L required no major modification. The right side engine crankcase of the XR650L is already machined for the kickstart parts and they drop right in with no machining. I was worried that the kick stopper plate mounting holes were not machined & threaded, but as you can see here, they were and it bolted right up.

Other than the new parts, the only mod I had to make to my XR650L was removing the mounting tab for the rear brake switch from the rear brake pedal. I then hooked the existing spring to the same mounting hole on the brake lever that the return spring uses. In this picture you can see the broken off brake switch tab just behind the retaining bolt for the kickstart lever. Behind that you can see where I re-attached the spring from the brake light switch to the mounting hole for the brake pedal return spring. After adjusting the switch, it works perfectly and doesn’t interfere with the kickstart lever. I also had no interference with the bump out on the frame above the rear of the brake pedal.

 

Decompression options:

 

The original XR600R and the XL600 both had various decompression options over the years to make the bike easier to kick over. There was an auto-decompressor on the right side cover, which was connected by a cable to the head cover and was automatically actuated by the kickstart spindle and opened a valve on the head cover. There was also a manual decompressor lever mounted on the handlebars, which did the same thing, but you had to squeeze it when you kicked the bike. The XR650L and later XR600Rs have an auto-decompressor and an anti-kickback mechanism on the cam. Some aftermarket cams don’t have this so if you changed out your cam, you may need to add a decompressor. I was relieved to find out that the auto-decompressor on the XR650L cam was sufficient to allow the bike to kick over. I was actually surprised at how easily it kicked over. It even kicks over with no battery installed.

 


I bought all the parts that I needed on E-bay with the exception of the countershaft, which I bought from DGY.com. The part numbers and prices at the end of this are from DGY. You could have your existing countershaft and side cover machined, however it would probably cost the same as new parts and lets face it if your going to tear your engine down, why put a used part in there? The machining would be tricky as it is not a matter of simply drilling some holes. The side cover opening must be precisely machined to accept a bearing and seal and the countershaft would require a precision surface for the idler gear bushing.

 

I was very fortunate and got a great deal on most of the parts. The complete kickstart spindle usually sells for around $50.00. I got mine for $25 and it included a new idler gear and bushing along with a new bearing and seal for the side cover. (Score!)

I also picked up an XL600 right crankcase cover for $20.00. They also seem to sell for around $50.00. It had the decompression lever on it, however I didn’t install the cam on the kickstart spindle to actuate it, as it would have interfered with the rear brake switch. If you want a really clean look you could find a later XR600R right crankcase cover without the decompression lever but these are much harder to find than the mid eighties XL600 covers, which were abundant. The decompression lever is also hidden pretty well by the brake light switch.

 

Here is a picture of the right side crankcase cover with the auto-decompressor lever situated above the hole for the kickstarter spindle:

The only part I bought new was a countershaft for $100. I ordered a countershaft for a 1995 XR600R hoping that it would be a direct replacement for the one in my 1995 XR650L and I was not disappointed. It was identical except for the machined end for the idler gear. Gears & sprockets from an XR650L fit with no problem. The one in the top of the picture is the original from my XR650L and the one on the bottom is the replacement from DGY.

You can see the right ends are different and show the machining and oil hole on the replacement. I measured both and the shoulders on both are .40inch or 10mm back from the end. The diameter needs to be reduced from .743inch/18.8722mm to .628inch/15.9512mm. The oil hole is.080inch/2.032mm in diameter and located .140inch/30556mm from the shoulder to the center of the hole. All these measurements were taken with a dial caliper and may not be exactly accurate, but you get the drift. The XR600R shaft was also undercut where the reduced end met the shoulder. I couldn’t measure that along with the angle of the edges of the end of the shaft and the shoulder. None of those are critical and can be approximated to provide clearance for the idler gear. The critical dimensions are the reduced diameter and the fine finish for the idler gear to ride on. Initially I had hoped to have a custom bushing made and use the existing countershaft and preclude tearing down the entire engine, but there is no oil hole in it and the end is un-machined and way too rough to ever work. Replacing the countershaft is by far the most expensive and daunting part of this project, but is absolutely required. A shop will charge you several hundred dollars to replace it since it is very labor intensive. I called a local shop and they quoted $800-900 to replace the countershaft including the cost of the countershaft. I reluctantly did it myself and I must say that if you take your time and follow the manual, it is absolutely doable for an amateur. (Hey I did it!)

 

I used a Clymer manual and help from this forum to perform the kickstart conversion. I am not going to get into the removal of the various engine bits as you need a manual anyway, but you must remove the seat, tank, side covers, carb, exhaust, head cover, head, cylinder, right side case cover and engine crankcase from the frame. You then have to split the cases and change out the countershaft. You don’t need to remove the left crankcase cover but you do have to remove the starter. Disassembly took me about 5 ½ hours taking my time. A pro could probably do it in a couple hours. Putting it back together took about 4 ½ hours so figure a full day plus to do the conversion. I did it myself but a helper would cut the time down considerably. Big time consumers were separating the cases and carefully scraping off all the old gaskets. I separated the cases by supporting the edges of the right crankcase half with wooden blocks and rapping on the mainshaft and crankshaft until I could see light between them. I put a wooden block on the end of the shafts and used a relatively light hammer. I then used a soft brass punch to tap around the edges and get the cases apart.

One problem I ran into when replacing the side cover is that you need new copper washers for the oil line that connects to the side cover above the oil filter and runs up the cylinder to the head. I didn’t replace these initially and I didn’t get the hollow bolts lined up correctly and starved the engine of oil until I figured it out. You will want to mark the top of the bolts with a permanent marker showing where the hole is so that you can line it up with the oil line later. You also have to use Permatex spray hi-temp copper sealant on the head gasket or it will leak. I failed to use the sealant and had a nasty exhaust leak at the front of the head causing backfiring and rough idle.

 

Here is the finished product:

Was it worth it? To me, absolutely. It cost me $237 including shipping for everything including a new countershaft & gasket set. My time was free so that helped considerably. I will probably use it very seldom, but it is reassuring to know it is available. I will be happy to help out anybody who wants to do this conversion on their bike, either by phone, E-mail or locally if you live near Pittsburgh, Pa. I have pictures of the complete teardown and rebuild, but that has been covered in many other posts and would make this post really long. If anyone has any questions or requests for pictures let me know and I will edit the post to include them. Tools and parts list in the next post.

Great job. I'd like to add a kick starter to my 2008 XR650L. I wonder if the inner casings on it are premachined for a kick starter. That be great if all I had to do is add the spindle assembly and swap out the putter casing. I may be in contact with you if I do decide to add a kick starter.

      Rockstar Energy Husqvarna Factory Racing Rally Star Earns Third Overalll at the 2018 Edition of the Event in Morocco
      April 20, 2018 – (Motor Sports Newswire) – Determined to wrap up his week-long adventure in Morocco on a high, Rockstar Energy Husqvarna Factory Racing’s Pablo Quintanilla has topped the fifth and final stage of the Merzouga Rally to secure a solid third overall in the event’s final overall standings. Continuing to make progress Andrew Short has claimed a spot inside the top 10 in the overall.
      Featuring a mass, motocross-styled start in the dunes of the Merzouga Desert, the fifth and final stage of the event saw Pablo Quintanilla put in a dominant performance. Posting the fastest time for the day, the Chilean rally star solidified his strong third position in the overall standings.
      Putting in his best individual stage performance Rockstar Energy Husqvarna Factory Racing’s Andrew Short crossed the line in eighth position. Wrapping up the Merzouga Rally 10th in the overall, the American is content with the progress he made during the week in Morocco.
      The Rockstar Energy Husqvarna Factory Racing Team will return to action at the third round of the 2018 FIM Cross-Country Rallies World Championship, the Atacama Rally in Chile on August 11/19.
      Pablo Quintanilla: “Today was a really fun stage. We had the motocross start and it was good to battle with the guys from start to finish. I got off to a good start but five or six kilometres into the stage I had a small crash that dropped me back a few positions. Then I had to push until the end and 10km before the finish I got the lead back and was the first to cross the finish line. It felt really nice to win a stage that way. Overall, I’m satisfied with my third position in the overall. This was a tough race with tricky navigation and to be on the podium is always good. We continue to gather experience and look ahead in the races to come.”

      Andrew Short: “I really enjoyed this week in Morocco. Especially this last day was really fun, bringing back memories from my days racing motocross. Before the flag dropped the nerves were there and I was maybe a bit late off the start. It was a good experience racing alongside the fastest guys in the dunes and being able to see their pace. The adrenaline kicked in and I had some really good fun. Overall, the week has been great for me. I enjoy the atmosphere in rally racing and I feel I am improving, getting closer to the top guys. I might still have a long way to go but I understand it needs to be done step-by-step. This week was a positive step in the right direction.”

      Just picked up a XR650R -04 and it has a brake lever from different model. Anyone who are able to identify it? I need to order a new lever to replace the broken one but I'm unsure what to order. It looks like Honda OEM but its different from the master cylinder for XR650R. This one has a slot for a mirror. Apologies for the poor quality of the photos.

      GEICO Honda’s Eli Tomac Exclusive Interview (450 Class)
      Eli Tomac became the first rider to win his professional debut after earning the checkered flag at Hangtown Motocross in 2010 aboard at GEICO Honda CRF250R. The following year, Tomac signed with GEICO Honda, losing the 250SX West title by a mere six points. He came back with vengeance in 2012, earning the 250SX title. In 2013, he lost the SX title to Ken Roczen (then Red Bull KTM), but won the Lucas Oil Pro Motocross Championship.
      For 2014, he moved up to the 450 class with GEICO Honda, and though injuries prevented him from racing at many  SX events, he did earn his first-career 450MX win at Spring Creek.  Tomac returns with GEICO Honda in 2015 to take on the 450 class aboard the CRF450R.
      Ultimate MotorCycling’s Andrew Oldar: What are some of the main things that you learned in your rookie season of Supercross last year?
      GEICO Honda’s Eli Tomac: First off, it’s a long season, so it seems like it’s easy to get impatient early on. You don’t realize it, but there are 17 rounds, so it’s a lot of time to make it through the whole season. Unfortunately, I wasn’t able to do that. But you learn to be more patient as time goes on.
      UMC: You have traveled overseas for some Supercross races during the off-season. How have those results affected your confidence leading up to Anaheim 1?
      ET: I got to race in France and Italy and ended up winning both of those events. For me, any time you race against a few of the best U.S. guys and some top Europeans – and you beat them – it’s always a confidence-booster. Those were good for me, and it’s good to see our motorcycle is working well. I’ve enjoyed racing. It burns up some of the off-season time, instead of spending lap after lap on the practice track for a full month. I enjoy those races.
      UMC: What have you changed in your training regimen to prepare for this season in comparison to last year?
      ET: Honestly, I haven’t changed that much. For me, I feel stronger on the bike this year. I think that comes with age, getting stronger, getting older and maybe a little bit wiser. But I haven’t changed that much on my actual training program. It’s just building that base.
      UMC: You made the switch to KYB suspension. In what areas are they better than the Showa units?
      ET: I can’t say specific areas where it’s better. It’s just been really comfortable for me and I’ve been liking how it feels on the track. It’s definitely good.
      UMC: How much better is your 2015 race bike in comparison to your 2014 race bike?
      ET: I can’t say how good it’s been or how awesome it is yet because we haven’t gone to race it. But for how it was in Europe, I’m pretty satisfied with our base setup right now. I think we’re at a good starting point.
      UMC: You have been on the GEICO Honda team since you turned pro in 2010. How does it feel to have been on a team for that long and now be able to continue in your 450 career with them?
      ET: It’s nice to stay with a brand and a company and build that relationship with them and make it better and better throughout the years, if it is a healthy relationship. For me, it has been a good ride so far. I’ve got no complaints.
      UMC: You earned your first career 450 win at Spring Creek over the summer. What is it going to take to achieve the same result in Supercross?
      ET: There are a lot of good riders, and a lot of guys who are healthy this year, so it looks like we’re going to Anaheim with a full-packed gate of awesome riders. It’s going to take good starts because you can’t start in the back of the pack now and expect to get to the front because everyone is so fast. Good starts, good bike setup, being strong, and making through those 20 laps.
      UMC: Being that you only raced part of the 2014 Supercross season due to injuries, where have you set your goals for the 2015 season?
      ET: My goals are to win and be in the championship fight by the end of the series. I also want to stay healthy and stay consistent and hopefully be battling for a points title by the end of the series.

      Attempting to change the fork seals due to a leak in one fork on my 1984 Honda XR500R with Showa mg3-771 forks. My dust seals don't look anything like the youtube videos, photos, forums that I have researched. Also researched this specific fork and found nothing. Also I can only find information about models relatively close to my bike(XR350, XR400, XR600), but not exact. My dust seals seem to be permanently attached to the inside of the fork tube, probably some adhesive and has a foam ring underneath it that is deteriorating, hence the leak. Anyone have any ideas how to change the fork seals without removing the dust seal? Also noticed that the foam ring should be under the white plastic washer, not on top of, when compared to my other fork tube that is not leaking.
       
      Left Fork: Leaking, foam ring on top of white plastic washer
