I'm wanting to do crank seals on my 84 250R and have a few questions. First is there a manual I can down load anywhere? I tired the Honda manual section on this site and the only bike there was 350x, unless theres another area. And I tried on .org, I found the manual but it wouldn't let me down load.
Just looking at it, it looks like I might have to pull the engine to get the clutch side apart? Is that right? That would suck. lol. Maybe I can just leave the swing arm bolt in and pivot the engine back?
And also where is a good place to buy new seals? I'm looking for new ones, not never used 20 year old dried up seals. Any other suggestions are appriciated.

When I got the bike it had brand new 22 inch shredders on back. I really don't like 22 inch tires on sport model ATV's. My 85 250R came with a extra set of air cooled 250R wheels and new 18 inch turf tamers so I put those on immidiately. I like the look a lot more but its just geared to low like that so yesterday I put the 22s back it. It pulls much better. I've also got a jeswinehart 250R chain slider (missing) and Tecate boot (mine is fine but just incase) on the way. I'm getting a translucent red boot. Sweet.

I too would like to know this, I'm doing a refresher on my '84R right now as well.

I've been reserching since I posted and I found that Honda still sells the seals and they are only $8 and $13 each from Dillon Brothers Honda. I can't seem to find a gasket though, might have to silicone it.

The engine will have to come out.I just rebuilt a 84 250r motor and put a 300r top end on it. I changed the crank bearings as well.I got a after market kit from bikerchick on ebay both bearings and seals ..And a complete gasket kit from honda it was a Vesrah.

If your doing the crank bearings, may as well go with the cr500 as they are an 8 ball rather than the 7 ball stock 250r. little upgrade
