hey i have an 07 crf 450r. the decompression pin and the little nub that connects the pin the the shaft broke twice on me. i have Kimblewhite valves and dual springs. could the stiffer springs mabe be causing and issue? the first time it broke i didnt realy think much of it. but then about 20-25 hours later it broke again. i was also kinda wondering how hot cams are and how the decompression works. ive never really seen one for my bike.
