    XR650L Rebuild soon, looking for advice

    I have the jug off now to go to the machine shop tomorrow. Assuming this bike has about 30,000 miles on it, would you guys do new rings? I'd like to hear opinions. Personally, if money weren't a factor I would replace them even though they are probably fine. I might not replace them though because I just ordered a metric ton of parts for this machine last night on credit... Oopsie! But what happened is, I got the idea of a whole new direction for this machine. It's gonna look the tits when it's done, no bee ess. If yous guys stay tuned, I promise you will not regret it! In a month or twice this will be reborn!

    The valves are out of the head and everything was covered in carbon from the valve seals leaking, but the valves, seats, and guides all look fine. So that's good. I stripped the frame down for painting, going with Honda Passion Red on the frame. Guys, my only complaint about the XR650L is this ridiculous wiring harness which is always in my way and impossible to hide. I've already cut everything I could from the harness twice now and tried to "trim the fat" so to speak, but I was curious if there's any other options to tidy this mess of wires up?

    This is a bit of a speed bump. This is probably going to cost me some time and money. I was hoping to leave the jug on the engine and just do my head work then get it back together. Well I had two bolts break in the head, but this one that broke in the cylinder looks like it might have to go to the machine shop unfortunately. The two bolts broken in the head are flush. I didn't realize until just now how far in this third bolt broke. Never a dull moment!

    Just as an update guys, I've had to press pause on this bike just briefly. There seems to be a never ending cycle of machines around here, but unfortunately I seem to have misplaced my giant pile of money. Literally the day after I ripped apart the XR, an 85 ATC250SX popped up for cheap. We already have an 86 and 87 here, so I had to have the 85 to complete the three year run these bikes had. It was a great deal, don't mind the Big Red wheels on the back. The Hondaline ATC Speedometer will sell for almost what I paid for the bike. Also the Clarke plastic tank is a score as well. It's sun faded white, it's supposed to be red, but it will look brand new after wet sanding and new decals. Anyhow, since I bought that I have to let my funds replenish before I can order the XR parts. Here's the 85 SX. It's ugly right now but will look very close to factory original when I'm done with it. It will go under the knife after the XR is back together.

    OK good to know! I figured these probably didn't have a lot of cam issues when I got it apart because these cams are on ball bearings. All of the trike engines I work on do not have that. The cams ride right on the heads with those. Anyhow I'll run 10/40 in it once this engine is gone through and not using so much oil.

    I was using a 20/50 Hardly Ableson synthetic, which is excellent oil. I use it in all my air/oil cooled bikes. I liked the idea of a 20/50 in the XR since it was drinking so much oil, but after this I could run 10/40 again if I'd like to.

    XR650L Rebuild soon, looking for advice

    OK so I just read an old thread about the buzzing I'm hearing from the right side of the engine on cold starts. Apparently that's just the oil pump and that's a perfectly normal noise to be hearing, so that means I don't have to take the jug off or spend money on timing components which is good! Because I'm broke, lol! So I'll just concentrate on the head work and seals and whatnot. I'm going to paint the frame and engine also and I think I said I have to cut and straighten the swing arm as well? Well if I didn't say that already, I just did now.

    XR650L Rebuild soon, looking for advice

    Alright, it's the XR's turn to get some attention again. Today I removed the engine from the chassis and disassembled it. The head is off but not yet disassembled, and the cylinder is not off just yet. Just from looking at it now, the cylinder looks fine. I can see a lot of the cross hatch still and there is no ridge at the top of the bore. I'm thinking it doesn't even need rings. What I do know it needs is valve seals and I'll inspect the valves and seats once the head is apart. The valve seals were my first concern already. I have some questions I hope you all can help me out with. First of all, is there a common expected life for these timing chains? This bike has approximately 30,000 miles on it. I'd like to change the chain now if it's due. If you boys get far more miles than that out of these timing chains, please speak up. I'd love to leave it if I can. Timing chain guides- I thought my timing chain was a bit loud when I first start this bike up. I figured it likely needs at least guides just from the sound of it, but I never asked if that's just normal? It would quiet down after a couple minutes. I took a picture of one of the guides, I'd like to try and get some better pictures. Do these wear out around 30k miles usually? Also... I was gawking at the head after I removed it from the cylinder, and I flipped it over to look at the combustion chamber side. This little critter fell outta somewhere, no idea what that is. I'm sure I can find it no problem on the fiche, but I just thought I'd mention it. Yeah so in the past I used to take this up the roads during blizzards with it being street legal and all. Because of those times riding in all that road salt, a lot of the hardware gives me a really hard time on this bike. After the amount of work I had to do cleaning it all up last year from the salt damage, I decided this won't be going up the roads in the winter anymore. Trails and ice, absolutely, but the road salt is not worth it. I had three rocker box cover bolts break, one of which goes straight through the head and into the cylinder. Should be a good time getting those out. This is what happens when you ride in road salt. Thanks guys in advance for your replies and thanks for looking. I'm sure I'm going to have a lot more questions.

    Thank you Hollerhead! Earthcruzn, there is a massive oil cooler in between the triple clamps. That's where the 85 Kawasaki Tecate (where this front end was originally from) had the radiator mounted. I've never seen any temperatures above 160 degrees. The current final drive gearing is 13/36, which puts my maximum cruising speed around 55 with the ability to "sprint" to 65 or 70. I just replaced the chain and wanted to gear it a bit taller, as I have three countershaft sprockets and two axle sprockets, so I tried 14/36. Unfortunately I needed a half-link to get the right tension on my chain, so I put my 13 tooth sprocket back on.

    Thanks! Do you know if it's feasible to be done with then engine in the bike as well?

    XR650L Rebuild soon, looking for advice

    Hey guys! This might be a silly question, I don't know, so bear with me please! Is it possible to replace the valve seals on the XR650L with the engine in the bike and the head on? I know how to do it in engines where there is room using compressed air, I'm sure most of you are familiar with the process. What I'm looking to figure out is if it can be done in the bike with the head still on it. My plan was to run this pig until the winter and rebuild the engine then, however there's a race at Pine Lake in Ohio in September that I'm partially considering running in. Realistically I cannot afford to drive all the way there from Mass and spend a weekend racing, but... Should I pull something out of my arse and I find I might be able to make it, I'd really rather not crop-dust the entire track if it can be avoided. I'm sure the other racers would appreciate it as well, and my bike could potentially end up black-flagged due to the smoke if I did run it. Maybe it wouldn't get black-flagged but it would still look like shite clouding out the track. For anyone who is interested, my 1984 ATC480R ended up being an astonishingly refined machine once I finally rode it in Indiana in June. I had it running here well before my trip to Indiana, but there was no time to haul it somewhere to test it out before I packed it into the trailer. It starts and runs amazingly smooth for a half-liter two stroke and judging by vibration alone (or lack thereof), it doesn't feel at all like there is 480cc's of death between your legs. If you've ever ridden a 500cc two stroke, then you know what true vibration is. This bike doesn't do that. Now as far as power goes on the other hand, you definitely, absolutely, without a doubt know that there is 480cc's of death between your legs. This thing farking pulls, from off idle all the way through to the top, just obscene power on tap at any point in the RPM range. It walks away from 450 quads on the drag strip like nothing, which it should. I am tooting my own horn here by saying that this machine feels like something the factory made, and I'm not a braggart. Conversely, the XR650L conversion absolutely does not feel like something the factory would have ever made, but that doesn't mean it's not awesome. The 480 is impressive though, and as most may have guessed it is too much power. It will get you in trouble really fast, and the thing also sits there and idles like a sewing machine. The Keihin PWK makes that engine what it is, I'm positive. The only problem it had; it was getting hot and it would start detonating. It was near 100 degrees in Indiana and the trike should have had race gas in it. Not only did it not have race gas in it, but it actually had gas in it from the 2017 Indiana trip, so shame on me. I was given race gas mid-week from a friend but by then the weather had deteriorated and the 480R was put away from the elements.

    A simple fix for peeling decals on plastic tanks is to perforate them. I've perforated decals myself to see if it worked, and it did! I often look at things and say "I'd love to make a trike out of that!" Because of this site, my most recent "I'd love to make a trike out of" is the XR650R. I remember when these bikes came out, but I've never seen one in person and I haven't seen that much of them otherwise, so I thought it may have been a bike I made up in my head. I'm fascinated by them now and I'll be looking for one. With the amount of time I've spent on my XR650L trike lately, it makes me want a two wheeled version as well. A guy can dream. Sign me up for at least one of everything I guess.

    Hard to find neutral

    My clutch is not that old and it's tricky for me to get neutral from first. I can do it, it's not impossible, but I find neutral while I'm still rolling just because it's easier.
