I have used the Hotcam auto decomp exhaust cam in my 2002 WR426F before and while I found the simpler starting procedure helpful, the power curve the cam gave the bike wasn’t well suited to the type of riding i do here in the UK. The Hotcam seemed to give an increase in mid and top end power, where I find bottom and mid power is more useful. From what I have read on this forum, It appears that using the 03> YZ450F auto decomp exhaust cam gives an increase in power, including bottom and mid. Is this true? So to people using this cam, what are your experiences? Thanks for your help.
