Im looking at the white bros rev limiter, I want just alittle more power, will I be able to tell the diffirence with the rev limiter my mods are k&n no airbox lid, white bros e series, 170 main jet.

 

You can definatly tell a difference with the W/B limiter, I don't think it actually increased my horse power any but it does rev faster and pull longer in each gear increasing over all top end speed. I race moto cross and flat track and before I was always hitting the rev limiter.

99' 400ex, white brothers pipe, trac cam, piston,
rev limiter and air filter.
