Think it was the owners not being able to get along. If you look up my nameand at my past post you should be able to find my story. Long story short missed a ridining season and am still fighting my bike thanks to stuff they messed up.

A CR500 engine on Alky?! You're nuts, but I gotta admit that sounds like a lot of fun. My only question is how are you going to start it?

I've seen a cr500 trike on alky before, and the only way to start it was to tow it behind a truck or a car. Front brakes are recommended on that kind of a setup. I opted to have my friend put a parachute on his, but we never figured out a cheap way to repack it without using ballistic chutes?

Thanks again for all the input![img]i/expressions/face-icon-small-happy.gif[/img]

My only concern at this stage of the game is building up the ATC chassis where it's strong enough to take the heavy vibration from a worked CR500 motor. Any ideas on reinforcing the frame would be very helpful!

Well, it wont be as bad as if it were in a quad chassis. ATCs have front forks just the bike it came out of to absorb the vibs.
That shouldnt be that much of a problem.

That should be one hell of a hill shooter. [img]i/expressions/face-icon-small-happy.gif[/img]
