first off, i want to say i hate yamaha dealers, and every mechanic i have dealt with at a dealership is a fucking retard. i had a dealer install my tors kill kit a few months ago, and today, i was going to tune the bike. i was looking thru what they gave me back, and i noticed they only installed one of my dynojet needles and left one stock. so i pulled the slide out of one, and of course it had the stock needle. i put the dynojet one in, and i was ready to tune. now the idle screw that is on the choke side is really loose, like the guy screwed up when he tapped the threads. the screw will fall out while i am trying to tune it, from the vibration of the engine. it also seems like it is leaking air, until the jam nut is tighetend up against the carb. is this carb fucked now? could i use some teflon tape or something so it seals up correctly, or will it just burn up? i am not ever having anything fixed at the dealer, the only reason i brought it to them to do it was because i didnt want to screw up drilling into the carb.
