Just wanted to stop by and check on the CR500 stuff, I have a few pro hillclimbers on race gas & NO2 as well as some other cr500 bikes, been riding on & off for about 37 years yeah Im and old man, and have 4 boys that ride 500s as well. My wife even has an 98CR500AF its her sand bike I am building a cr500 that runs Alky and will have race gas & NO2 injected with a wet kit, it has a override tranny, Its kinda on the back burnner right now. I took it to Pismo for its maiden trip and found that I have a few problems to work out.
