I bought a jet kit from ProCycle and I'm planning to tear into it this weekend coming up. However, in a letter they sent with the kit it says that the numbers from the kit I bought will not match with the numbers from the stock jets. It says: "For best performance, ProCycle recommends installing the #125 main jet, the #34 pilot jet, the enclosed jet needle, and one shim under your needle clip." Do you have any experience with this kind of kit. The lowest I'll be riding is 4500 ft above sea level, up to around 10,000 ft. Any recommendations? Thanks a lot!
