Replace those cam chain guides and check the sprocket on the crank, it will come off with some heat.

Clutch basket looks good. I’m going to replaced the clutch kit and get a 115cc kitaco house brand cylinder, piston and assembled head. The old head assembly passed a water test. The cam tore up the cam journals. That’ll all be replaced as well as an oil pump, cam and cam chain.

Well, I finally got around to tearing her all the way down. Doesn’t look too bad. The gears are not all rounded off and chewed up. Quite a bit of metal shaving due to the cam and cam journals. Timing chain and sprocket are ready for replacement. Is there anything I should pay particular attention to here that I may...

Honestly, I have back to 1993 models of XR 100's and I think I have only done 1 crank in all of those years. I run 10w40 yamalube and haven't had any issues. You can ask Plowboy, mine get no mercy.

Do a bit of searching and seek out an XR100 forum…there are some rebuild kits out there that’re affordable. Do your homework and find out who makes the good stuff. Have fun with it. Those are great little motorcycles.

Yessir it definitely needs some work. I haven’t looked at the clutch but assume it’s toast. I’ve thought about replacing the crank while I’m in there but the money adds up and I’m not sure if it’s worth it.

I have to split the case to replace the kick start shaft. While I’m in there, should I put a new crank and all in or replace the shaft, any worn parts, jug, piston, head etc.? Then hopefully enjoy it for many years as I’ll never get my money back out of it.

If you're interested in having someone wash your boots for you, then you've come to the right place. As far as the XR, big bore pit bikes are a blast. Do it and have a great time. When your kids are ready for something faster then you can still use it as a pit bike for you...and I promise they will still want to ride it for messing around off the track.

I just did a BBR 120 kit on a late 90's XR100. Added some power, but still isn't anywhere near a modern 85 race bike. The XR is what it is - a playbike, or a good pit bike to race in a pitbike race. It is a GREAT beginner bike, because race bike tends to scare beginners. If your son gets serious, and can ride the XR for all its worth, your gonna have to save that money for a real race bike. Oh, and STFU NOOB! :-)

That's a big carb with a really bad air filter, but otherwise good. The tensioner pulls down to load (I've known NASA engineers that couldn't figure it out). Don't go for max power, just have fun on the thing and when he can wring it's neck everywhere start to look for a race bike!

I’m looking at replacing the head, jug, internals and cam holder too. Thanks for the heads up on the chain tensioner spring. Probably a little overkill.

The 98 XR? Sure, the big bore is fine. I would also replace the valves and cam chain, pay attention how the cam chain tensioner work's as it's spring loaded and the lock is what you release last. Enjoy riding with your kids

Thanks and stfu right back at everyone. Shit..I must be in the wrong place, huh? Dirtbikes? Does anyone have any advice on which way to go with this bike; besides sell it and get a bigger bike?

How’d this project turn out? I just got a 98 xr100r for my son and looking to rebuild to a 120 at minimum.
