426 needs a CDI....
Hey there, this is my first post, and I have a very important question.... I have a 2002 400ex with a JE 426 11:1 compression piston, Hotcams Stage 2 cam, White Brothers R4 Full exhaust with shortened can, 165 main jet, needle moved one notch, Moose air filter, and Racing clutches... The stock CDi is killing me.. This engines revs FAST, and I'm still making gobs of power by the time I hit the limiter... My question is, which CDI box should I run? Ebay has Hotbox's and Procom's (or something like that).. they are at a good price, but I've heard bad things on the White Brothers.... I want something that will give me a better timing curve, and Higher rev limiter... any suggestions? any of you ever used one a bored 400? Thanx in advance for the replies...
