I bought an '85 CR500 on impulse a while ago. It starts, but needs to be rebuilt. The PO had it for over 30 years and never had the cylinder off. He said it had recently become, "...harder and harder to start out on the trail." No shit...LOL.. 30 years. It probably still has the original piston in it.

Anyway, It seems crankshafts for these are no longer available (at least from my quick searching...nothing from OEM suppliers nor from Hot Rods). Can the original cranks be rebuilt?

The water pump housing is leaking. Looks like that can be remedied with a newer aluminum one? I'd be tempted to try my hand at epoxying the old one first.

I'd like to try this thing out at Superstion...but I'm not sure if parts are going to be too difficult to find to make it worth the effort.

Is this group still active? Do any of you ride the SoCal desert....like Ocotillo Wells or Superstition?

Nice old 85. I got one also and it runs tits!!! :D Welcome to the boards, its kinda slow on here but its home :cool: I to am in Californication. I converted my 85 to an 86 ignition and head. What a difference is starting :shock: Get the aluminum side cover. If you can1t get one I have rebuilt OEM covers for sale.

Kris, that bike looks fantastic!

My biggest question right now is what to do about a crankshaft. Apparently the 85-86 had a different crank than the newer ones? Honda doesn't make the crank or rod kits anymore for these (at least not that I've been able to find). What are we doing about that these days?

This engine hasn't been apart since it left the factory. There aren't any strange noises or symptoms that necessarily indicate that the crank is bad....but if I'm going to try to make a runner out if this relic, I'm not going to put a fresh top end on 35yo crank bearings. What did you do with yours? I mean, I suppose I could change the main bearings and seals and run the old rod bearing, but that just seems....wrong....??
