i have a 2009 650r with 3k miles, i installed the pcv with a yoshimiura trc slip on and stock air box running on 93octane. there is a noticiable difference except a spit and fart from the smog pump. is that normal? is there anything that can be done to correct this? when this happens it seems to loose alot of power, it only happens when i slow down,down shift and begin to accelerate. my brother has a 2011 650r same mods and his seems fine also more responsive. any advice or tricks would be apprieciated,thanks
