cam and rev box

[shwngo]

i have an 05 400ex it already has an lrd slip on. im adding a big gun rev box and a stage 1 (i think) cam, is there anything i should be careful of? What should i expect to gain?

I gained monster low end power with mine. Have fun, you will love it. The only thing is with some lower end rev boxes, you will have problems with cold starts. Not a big deal though.

got the cams and jet kit done it ran great, put the rev box on and now it's not wantiong to run at all, backfiring and running very rough. any suggestions?

ya i was thinkg the same thing but i herd that a stage 1 cam is almost the same as stock. Also what other rev boxes do they make that are a lil better than big gun

Holly cow.... there was a night and day difference when I installed the stage 1 cam. Whoever told you that didn't know what they were thinking. Also, GT Thunder makes a great rev box.
