    1985 XR100r ignition coil

    Some other tests I’ve done and may or may not be relevant. Plug test light from points/stator wire to ground and kick over engine. I get flashing light. Do same between spark plug cap and ground same result- flashing light. I feel like this means I’m getting power to end of spark plug cap but put in spark plug and ground to engine and nothing - same with multiple known good plugs

    I’ve ran some card stock through the new points. Figured since they are new they wouldn’t need more than that. To time then I removed the left wire from the stator, installed the flywheel and plugged an ohmeter to the stator points wire coming out of left crankcase and ground. Turned flywheel by hand and needle went from right to left depending on points open or closed. Set points to open at f mark then returned left wire to stator. Long story why I know this works on my bike.

    New points and gapped properly.

    1985 XR100r ignition coil

    Can someone explain to me about after market coils? Honda no longer makes 1985 XR100r ignition coil and internet searches on it are all different. After market coils are all different but claim to work on that bike. Some say 6volt some say 12 volt. Some $7 up to $30. Some are sold with cdi but the ‘85 is points. None give the primary or secondary specs so that’s no help. I’m pulling my freakin hair out here! Please point me in right direction. in addition, and what has spurred my search for a new coil is this. When I ground spark plug and kick over get only a few sparks then nothing. And primary reads 0.1-0.3 ohm and spec is 1.3-1.7ohm. Secondary is within spec. Is the above symptom consistent with the bad primary spec?

    Cylinder and piston within spec but near limit, bought 1 oversized new rings and all but 1 ring was in spec so filed end. Crossed hatched so so not perfectly at 45 degrees but maybe 30 degrees. Put it together. Kicked over with compression tester and it’s not great. 120 psi. Should I expect it to get a good reading right away or does the engine have to go through it’s break in/ heat cycles before it will fully seal?

    This seems wrong. Manual says .15 to .3mm and this is about 5mm

    Update on this project. After all the work done to it the engine started a couple times and ran horribly and now won’t start at all. So top end came off and it’s no wonder it didn’t start. The rocker arms are destroyed, the cam shaft lobes are pooched. There was oil up there but not at those spots. When I removed rocker arm holder everything was covered in ground metal residue and all the channels and holes for oil were clogged with the same. Piston and cylinder look good and no movement on con rod. Will check ring clearances and hopefully just have to hone cylinder we will see. I wonder if my oil pump is buggered or was it enough just to have those passages clogged that stopped oil from getting there.

    Is there a situation where a bike can have decent compression but still need a rebuild? The few times I’ve had the bike running it doesn’t run well, and there is a definite clanking going on. I’ve changed oil twice and a lot of metallic in it. Just gauging opinion before I tear it down.

    When the cam chain sprocket loosened it resulted in the woodruff key getting sheared and messed the timing. Got a new key and learned the hard way I need to torque the flywheel nut before I ride the bike, sheared the damn key again. Before it sheared the key it was running well but does feel like the clutch slips. Revs up but power stops making it to the rear wheel. Woodruff, clutch, fork seals, steering head bearings and rear shock bearing and she should be good to go.

    I think it is 130-58. I do need to fine tune the timing. When I got it going it started clicking under the valve cover. Shut it down and removed the cover to find the cam chain sprocket had loosened. Tightened the sprocket but now I think cam chain is loose. Didn’t have time to investigate further but will have to look at before starting up again

    F130 is stamped on flywheel. Installed a new aftermarket carb on it, and switched spark plug cap to a resister cap and she runs!! Idles ok but at full throttle it wants to stall and backfire and lose power. So some fine tuning to be done there. Thanks again to everyone’s help. I’m sure as I get deeper into this project I will have many more questions

    No backfiring. I think advance moves smoothly, nothing to compare it to. I can easily move it by hand and it springs back. How does one check for crank slippage?

    I messed around with moving the point where the points open but nothing as drastic as that. I will have to give it a go. It got me thinking- this bike was a total mess when I bought it so maybe the flywheel is from another bike that had the timing mark on the case in a different spot; or something outside the box like that. Shoot me any crazy ideas like that if u got them

    Did a simple leak down test today- no gauges just air in cylinder on listened. Heard just slight leakage at oil filler. Did another compression test and got 135psi. Started thinking about plug and cap. There was some discussion somewhere about plugs and caps, resister type or not. I believe the cap that came with bike was nonresister type but the plug is resister style.I swapped to a resister type plug cap and was able to fire the engine a number of times with carb cleaner in the intake. Yippee the first bit of progress in couple of weeks.

    Does anyone have a link to 1985 XR100r service manual. I’m normally able to locate just about any manual for any bike online. Even found the manual for later cdi versions of the xr but not the points version. It’s strange considering they must have built thousands of these bikes.
