650sx impeller advice
Hi, I have an '89 650sx with a stock engine, no mods other than handlebars and an extended ride plate. Looking to upgrade the the stock impeller, and would like advice on the best choice. I'm 170 lbs. and just looking for better overall performance for recreational riding. Stock impeller seems to have decent holeshot and midrange but feels a little under-pitched at the top end...
