I got my rcr stage one kit. Installed it, everything is great. The question I have, the primary spring that I installed is black with an orange stripe down one side. Does anyone know which spring I have? I tried emailing Rick but he must be way busy. Also does anyone know if the 39mm TMX card that rick sells will work with my quad without any mods to the engine. The quad that I have and that I installed the RCR Stage 1 kit on is a 02 TrailBlazer.

Thanks all
Jason

 

Not sure what the black spring is but the 39mm TMX is way to big for your quad and even a highly moded one like mine. You would be able to get away with a 34mm carb in nearly stock form and a 36mm with lots of mods. Another thing you might want to do is look for a pwk or pj carb from keihin. It is a better carb and much easier to tune. Stay away from the 39tmx.

 

I have the black with orange spring ,It is a Dalton spring. Works good with the pipe and porting I have.
