seems like most of the florida boys around sea level run their jets with a 170 jet. in central ky im also running a 170 jet not any problems so far. its a little rich but with a 165 i was lean.
he is adding aftermarket stuff to carb.I'd take it back to the dealer. That bike is supposed to be set up for the area you ride in. Obviously if the carb adjustment is out of wack, they didn't do a very good or thourough pdi inspection of the the thing, of which you probably paid extra for as most places charge for that.
No prob most of the stuff I know I learned from people on here so just trying to give back. Where do you usually ride? Have you ever go to 5A?I found that that problem I was having was cause by either the 1.5" spa hose I was using was to small in diameter or the way I routed the hose.It was not allowing enough air into the airbox.So I made a new snorkle using Marcust's setup.and put a 170 main jet and needle on the 3rd slot down and now the bike run's great.But I think I am going to try a 175 main jet and see how it run's.I will post the results when I try that.Thank for the post Marcust!
