[ebo 4356]

im debating on if i should get a rev box because people are telling me if u ride 5th gear pinned it will blow up, i ride hillclimbs and usally 1st gear pinned what would if i used a new rev limiter will it blow.

Don't think so. The racers will know better though.

like i've heard before a stock 400ex prolly doesnt have enough power to top out in 5th........... but either way i think you'll be fine........ i've went 5th gear pinned with my rev box past my friend just cuz i got tired of him being cocky about top speed...... i have a few mods too.......... but you'll be fine and you won't blow your engine....... just dont hold it reved out for ever....... all its gunna really do if its reved out for a long time is exhaust gases are gunna blow past the piston rings and just break down your oil quicker
