vanishing oil...

Recommended Posts

on my 1993 Honda XR650L. I just re worked the engine. (new countershaft, timing chain guides, and a cam) I put it all back together and it fired up. so I took it for a short ride. I got it back and checked the oil level. Empty. Weird I thought. so I drained the oil. Nothing out of the oil down tube. I removed the engine drain bolt and all my oil came out. So I changed the oil and added 2 quarts. started it up and nothing on the dipstick. added another quart (just to see) and sure enough it disappeared too. I am not sure if I have the lines crossed (smaller one on the inside right?). I cant figure out what I did wrong. please help.:smirk:

its been sitting for six months until I could afford the parts so I am a little frustrated with myself.

If you added a third quart of oil, you are probably a quart high, unless you have an oil leak. :smirk: You should only check the oil level after the engine has reached operating temperatures. When the engine is hot, check the oil level with the bike upright, immediately after you turn off the engine. :prof:

Spud :smirk:

Hate to ask a stupid question but you did put the gear back on that drives the pump right?

OK so now we're past that make sure pump is primed, and I guess you cross oil lines but I think it would be hard to make them go on wrong, not much room, or length in the hose to getit wrong.

Close. I went online to where I buy my parts. turns out there is a small metal line I forgot. My service manual didnt really do a cracker jack job of mentioning it and I forgot. :smirk: I will throw it in and hopefully that will take care of the problem. Got lucky and didnt cause any damage.

yes there is and there should be an o-ring on that tube, be careful not to let the tube slip during assy. and get cocked in there, I have seen it. (not me of course but I have seen it).:smirk:

okay. got it all assembled. still didnt have oil reaching the frame by the dipstick. pulled it back apart and reprimed the pump. still nothing. so i cracked the return oil line. very low flow until i assume air escaped because the next thing i know my face was covered in oil. so now its flowing properly

quick question though, I installed a hot cam as well as a dynojet stage one kit. its popping on decel, running hot, and stumbles and dies on acceleration unless i really get on it. Cruising speeds it flies though. Maybe I need to go with the next jet up that I got? The kit came with a 160 and a 165. I originally had a 158. so I went with the 160. Bigger? I dont think its the valve timing as I was overly meticulous with that. lets just say I learned my lesson after meeting an interference engine. :smirk:

Like you, I recently rebuilt my engine and installed a hotcam. In addition to that, I added an ISD-2 exhaust and used a JE 10.5:1 piston. The jetting can be finicky and you may have to experiment some. Research what other are using, Dave's Mods are a great place to start. I am not familiar with the dynojet numbers, I use OEM jets and needle; suggesting same for you.

Your bike sounds lean to me; popping on decel indicates either that or an exhaust leak. Start with one circuit, work it out, then change the next circuit. Too many changes at once is too confusing. You'll get it eventually.

      Hi all!

       I've got an issue, one of many when it comes to bikes. I searched throughout all the pages I could find pertaining to my situation and couldn't find very much useful information.
      So the issue is, the bike has no electric start.... until it's hot enough to melt steel that is. It will bump start first time every time. But I can sit and crank the starter over for ever and it'll never start until the charger is bumped up past 200 amps. Not good.

       The story so far,
      Got the bike for 1k cash. Guy said it has no spark and no second gear. This particular guy also only ever rode newer crotch rockets. Brought it home pulled the choke, attached battery charger and she fired right up. Ran like absolute crap, but oh well I figure it's an older bike with only 10k miles so it probably needs a good carb cleaning. Took the carb apart and didn't know I messed something up until way later(didn't tighten down main jet). Oh well she runs well enough if I can get her started. Moved from California to Oklahoma. Eventually found the money to fix 2nd gear, and as I am a certified Honda small engine technician apprentice I figured it would be no big deal. Completely tore down engine to it's roots replaced 2nd, and 5th gear(because 5th gear connects to 2nd on the countershaft) dogs were worn pretty badly on both. The engine looked quite good compared to most others I've seen. Put the engine back together as per the service manual. Did all the right steps including loosening the banjo bolts to test for proper oil pressure. I even tore apart the electric starter to clean the contacts and the brushes and replace the dielectric grease. Adjusted the valves as per the service manual, replaced all gaskets, o-rings, seals, and oil filter.
       Finally after about a month of waiting on parts and reassembly I get to start her, only she doesn't. Electric start is still giving me the same issues I've always had. So I replaced the Ignition coil, CDI box, and put a new battery in, plus the starter motor rebuild. Nothing. Still cranks forever. I said what the heck and tried to push it slightly down hill and bump start it, and voila... fired right up! Once she gets hot enough and the stator charges the battery enough it'll electric start... sometimes.
       So I looked towards ignition, used a tool called ignition mate. Pretty awesome tool if you can afford it. Well while cranking the ignition mate reads the spark plug is getting 1-4kw of "spark" every cycle, well it only fires after getting up past 5kw sometimes 6-8kw. And sometimes the ignition would be intermittent as in it wouldn't give any spark at all. I cycle the ignition and it seems to soft reset the bike as it will usually give it back spark. I tested this with the new and old CDI box, the old one would never spark. Ever. So I threw it in the trash. A month later I stil l can't figure it out.
       Is there something I'm missing?

      TL;DR
      Bike won't start using electric start only bump start before and after engine rebuild
      Electric start works after pushing the starter past about 200 cold cranking amps or when hot.

      Contemplating picking up a BRP in the near future and looking for some perspective.The current owner claims that the bike has about six hundred hours on it, but there's no way for me to confirm as the odo's not accurate.
       
      I know brp's have a reputation for running forever on stock top ends, but they must eventually have an expiration date. What should I look for on a high mileage bike like this to make sure I'm not setting myself up for disappointment? Also, What are some non engine/transmission related issues I should look for?

      Guys, 
      Have been riding my 650L for over a year and a half and have been loving every second! In August I moved back to Reno after finishing up my masters at Arizona State. I have been spending most of my time riding around verdi to stampede and the Dog Valley road area. Always looking for riding buddies. 
      Was curious what everyone was doing as far as Daves mods or jet kit for the upper elevations 4,000 to 8,000 feet?
      FMF Q4 exhaust, smog delete done so far!
       
      Thanks!

      Hey dear folk!
       
      I need your help.
       
      A bit of background info, I’m a complete noob when it comes to holding a wrench and doing anything more than filling up the bike. I have however had an interest for as long as I’ve had a bike to make it mine, and that’s why I’m writing to you now. I just bought a donor bike, a Honda NX650 which a friend of mine is helping me fix up and then modify to my liking (I’m hoping to end up with a gorgeous scrambler in about 9 months).
       
      We found a hairline scratch in the cylinder and need to bore it. This leads me to my question.
       
      Should I get a 1st overbore performance piston or keep the compression ratio as is? If so is there anything in particular I will need to modify to tolerate the high compression piston?
       
      If I do get the performance piston, should I also get a new carburetor, hot cam, and new exhausts? I am planning on new exhausts anyway (2-1 from an XRL) and I’m planning on removing the airbox and getting a K/N pod air filter.
       
      Again, keep in mind I know nothing, my friend has however fixed up a bunch of XRLs and cars but never really used performance parts. Help me out with the decision please, I would also like to keep the whole build to a reasonable cost (I know this is a very relative number).
       
      I should also add that I want to keep the DNA of the bike, for example keeping the fuel tank instead of switching to a smaller rounder one as one usually sees in most custom builds. The aim of the whole build is to have an insanely fun bike to ride, both in the city and off-road, as well as giving it a bunch of my personality 😊
       
      Thanks a lot for any help!
       
      Best,

      I've been rebuilding/restoring an XR650R for some years now (after toasting the motor in 2013). Sent the motor off to be rebuilt, had a local shop rebuild my forks and shock, and took care of most everything else myself.
      As of a couple months ago I had almost everything assembled and ready to run.

       
      As a final check before adding fluids to the bike, I decided to stick my boroscope into cylinder and take a look. The results were concerning.

       
      These boroscope pics looked so gnarly that I pulled the head off the motor to get a more thorough look.

       
      To say that I'm concerned is an understatement. I have pics of the motor internals pre-rebuild, and can confirm that this is definitely a new piston and replated cylinder. I also have all the old parts from the motor, so it does have a new cam, connecting rod, valves, and basically everything else I expected to have replaced.
      The builder "ran the motor briefly to confirm everything ran alright" and then shipped it back to me. I reached out to him with these pics and he said,
      The piston looks like this because he had it machined from 12:1 to 11:1 compression. The streaks on the cylinder wall are normal for one that isn't broken in yet. Regarding the valve impacts in the piston head: "My concern is that something may have passed through the cylinder. How does it run?" I've never run this motor. I can feel these streaks in the cylinder wall with my fingernail. Did he re-use a piston from some other motor?
      Is this dude jerking my chain or is this motor fine to run?
      He's a fairly well-known builder in the XR community and was recommended to me by guys in the (now-gone) XR650R forum.
