Well I have a blaster I built for my lil brother . We picked up a few blasters one came with the pipe . I put a vitos stroker crank in mild porting and put a oko 28m carb on it thought it was a keihin carb . Runs alright just wondering if the pipe was worth keeping. No head mods yet I'm going tosend one head off to flow tech to do a head mod. But it seems like I need a bigbore to better suit this pipe .
