CRF80F woes

Any half blind moron can see that a 6' 185lb guy on a CRF80F isn't going to be setting any record lap times. The CRF80F is the redheaded bastid stepchild of Honda dirtbikes, you can get whatever you want for the Fiddy's and a whole lot for the 100's but the 80 is lucky to have 10 aftermarket products available at any time.

Still, it's a fun little bike, it's paid for, and it doesn't cost much to keep it around. So yesterday I received a nice box from WPS that had a set of handguards, new grips, new dirt helmet (which can do double duty on the BMW in the hot hot sumer as a dualsport helmet) and a few other little cool bits.

As I'm mounting the generic handguards I step back, have a look and realize they are not lining up with each other. Fiddle and tweak as much as I like but one is still pointed an inch lower than the other. I saddleup to survey and guess what... the bars are totally wonked. Must've happened a couple weeks ago when I heavy lowsided my head into the ground and felt my brain shift inside my skull.

Back to the computer at 9:30pm, ordered a new set of bars and head bearings too, might as well while I have it apart.

Which brings me to my question... While I disassemble the front end to replace the bars and bearings I want to add heavier oil to the forks (no spring upgrades available) - I can't figure out which oil I should use, or even the process for draining and filling these little forks. Any ideas?

surprisingly yes, it's as much fun as a trackday in many respects. The more weight I lose the faster I get.

so last night I was cleaning the CRF80 and was upset about all the nicks & scratches in the frame, swingarm and forks. I looked through the toolbox and found an old assortment of Testors model paint, you know those tiny jars? There was a silver among the choices, sure enough it was a near perfect match.

A little detail brush help with some touchups, then I donned rubber gloves (prostate exam style gloves... I hear you shrieking) and dabbed a papertowel in the paint and rubbed it on the frame. A perfect blend. Other than the minor plastics scratches the bike now looks brand new.

XR 80

Hey guys,
Just picked up a lightly beaten 80 for the kids... supposedly.. and wondered if anyone had a service manual in .pdf format lying around. It runs great and can even pull my large arse around at quite a clip, but it's leaking a bit of oil and I'm sure could do with some maintainence.

Any help would be greatly appreciated.


Shawn

BTW: A fat guy pulling wheelies on an 80 is quite a spectacle, you can ask my neighbors. But it's the most fun I've had in a while.

Congrats on the new purchase. Pics of the claimed wheelies are necessary now that you have mentioned them.

My 93 xr100 had bars that were like 3" off from the left to the right, and the thin crossbar on the middle was bent into a U, shaped oddly; very much like Ridgerunners forhead.

I'd tell you to ask him about it, but I'm not sure he remembers that Saturday, just blurred glimpses of sky and weeds and then it was Sunday.
