Great for racing

Comments On Dec 14, 2013:before I installed these high rev springs I had to shim my valves after every couple of rides, I have had these in for about 5 months now and rode them hard for the whole weekend non stop and haven't had to adjust the valves at all, Love these springs.

shim would not fit

Comments On Nov 23, 2011:Bought these for my 06 crf450r and 3 of the 4 were great but one would not let the shim seat in. Tried multiple new shims (hot cams). made it work but took some time.
