[ManicMushroom]

what would happern if you made it so the RC valve (power valve for hondas) was open all the time?

as i have seen someone do this to there nsr125 on another forum and use it for racing, but never found out what it went like.

powervalve adjust airflow a bit like vtec

it has two settings depending on speed and used in a 2 stroke

I know that when I did Cadwell, my powervalve pulley broke on the second lap, twisting the cables and leaving it in the open position.

It was fine down the straights as long as you kept the revs up to get decent drive out of the turns. If you let the revs down the bike would just keep bogging down.

I managed to get through the race okay but it was a bit scary. Keeping the revs up in the chicane and feeding the power through the clutch nearly gave me a highside. Definately a 50p/5p moment.
