CR500 Motor Recommendations

[big specht]

I'm looking to build a cr500 for a pulling bike I'm looking for info on where to get parts or who is good with these 500 motors if I'm going to spend the money I don't to blow it on any rum dumb with a grinder. I'm looking for a drag pipe for it too. I'm probley going to use the cr500 frame and make it a 3 wheeler.

Try LED Performance. They are doing custom pipes and Arlan is a magician with porting. I was looking at one of my old cylinders. He ported it in 2001. The serial number was over 1900. That means in 2001 he had almost 2000 ported cylinders under under his belt. I'm not sure what he is up to now.

Anyways, check them out, definitely worth a call

Best regards

I would suggest you build a CP Industries Liger cylinder you can get them in 94,97 and 102.5 bores
my 97bore x 83stroke dynoed 110 at the rear wheels on methanol

I'm not sure if I want to go with the liger jug cause I know what this will make a great big snow ball that going to require a lot more parts to hold and use the full potential of power those parts can make BUT DAMN it would be fun to ride lol. Thanks for the info so far I just need to sh%t or get off the pot on this project

Well i have a 86 and a 89 cr500 witch motor should I use ? I know the 89 need the crank rebuilt thats why I'm planning on stroking it while I'm in there

One name for cr500..glen howell at gss raceporting..he's doing a full port race cyl for my cr500af now. Nobody comes close to Glen on cr500 work. Be prepared for a long wait, he is really popular with the guys in the know.. could be several months till he gets to your cylinder but well worth the wait!

IIRC, 89-92 cr500 had a closer ratio transmission than the previous and later models. I prefer the wider ratio, but I'm not pulling on a trike either. The close ratio of the 89 might be better suited for that than the wider ratio trans.
If I get time I'll look up what years had what ratios for sure. Or you can check Google or cr500 riders forum

Talk to Roosty over cr500riders.com. He'll point you in the right direction(be sure to post first in the intro section). Roosty should be able to fix you up. If nothing else you can check out some reports on GSS and make up your own mind. My cr500 is a bike. It really doesn't need any more power(it makes enough for me and I'm used to riding liter bikes on the street). BTW 86 parts are harder to find.

BTW mine is a 85. Honda did mellow the cr's over the years. I've thought about doing an af conversion with my other 85 motor, but I really like riding the steely, drum rear brake and all LOL.

I think u and Everyone else knows exactly were they went. Go ahead and advertise somewere else. This is a 250r forum.  Not a sell my cr500:  crap forum.

Why dont you (CR500 guy) post your OWN thread in the Lounge....from time to time their are some that run a CR500 in 250r frames......But don't think your going to start posting in every thread pitching sales for your business....I don't care if you are a CR500 Guru your not going to wreck this site like the other .Net site was......

Why did you guys delete the posts?  I was really interested in that dirt bike chit.  I have been looking for a guy that could do that mod on my quad- remove two of the wheels but add twice the cc's, im down.:greedy_dollars:

[udontknowme]

and a extra 50hp. sheesh who wouldnt want that

[big specht]

What was that place he was advertising for i think he is in pa that's somewhat close to me
