I just want to tell everyone to not use HD valve springs. I just smoked my brand new Kitaco cam and rocker arms!! was only ran for about 3 hours.. I guess I should have done a search on this and seen what people have said about them before I used them.
002 is wrong should be 005 thats your problem i run hd springs and the work fine in 2 different bike one with a stock 50 head with a bigger intake valve and takegawa cam and the other with a hrc head also takegawa cam
