Ive heard of this vid and I just watched it. I'd hate to imagine that this could possibly be happening to my gal old $400 Bonito . Has any of you guys incountered this problem? My engine man seems to be sceptical that this is a air leak problem but he has done this repair for a buddy of mines recently and is waitng to see if it fixed his problem. Have any of you guys experienced this problem and is it reccomended to get this done to be on the safe side? Also has Novarossi said anything about this?
