Last Saturday, I installed a 75mm plenum. Since the computer has time to adjust, the limiter is now kicking in around 6300-6400 where as before it would activate just past 6000.

Is this change bad for the motor because I also want to uprade to a 75mm TB?

That should have nothing to do with the rev limitor. The rev is all done by computer and not air/fuel leanness! Also, you should have no need to go above 5300rpms with a 2v motor. They start losing power after that! 5500rpms shifting max, but you shouldn't hit 6k ever!

Spinning a stock motor about 5500 gets you nothing, like he said. Also, about 6K, you're asking your pistons to seek work elsewhere.

got it, thanks.
