Had some hiccups when installing had to Dremel a small amount of a fin to fit over the stock oil pump on my Eton beamer matrix....but after installing and tuning the carb and getting a different air filter she runs great no bogs at all I'm getting 52 on flat with the current stock setup with the yasuni exhaust I expect to see 60 or better. Stock 18.5mm maikuni carb, Athena carbon fiber reeds,k&n POS filter, upjetted from stock 80 to 90 main jet, ngk r spark plug.
