i sent an email to ryan. he said it be good. and then couple others i talked to said with a rev box it'd be fine. might put it off for a little while though. i hear i'd see a bigger improvement in my riding from gettin a set of street tires than i would tryin to rework a carb so think i'm gonna get the rubber first. my carb seems to be runnin pretty fair right now cause the temperatures are back in the usual florida range.
