SupermoTom Posted March 7, 2009 Share Posted March 7, 2009 i have fitted a arrow exhuest system to my xt125 some told me to put in a bigger jet i phoned up a shop about it they said it is not worth it would any one now if it is or not it's not gonna give it a million bhp if thats what you mean lol. it will make a difference, it'll be noticable, but not a massive difference.

bobbyhollie05 Posted March 8, 2009 Author Share Posted March 8, 2009 have you any other ideas as it is a slow bike Link to comment Share on other sites More sharing options...
Moderator Airhead Posted March 8, 2009 Moderator Share Posted March 8, 2009 They are slow compared with DT's, but its worth getting a bigger jet for it, ask your Yamaha dealer to get you the next size up from standard, it wontt make it a fast bike though i'm afraid.

bobbyhollie05 Posted March 8, 2009 Author Share Posted March 8, 2009 would you now what difference it would make Link to comment Share on other sites More sharing options...
Moderator Airhead Posted March 8, 2009 Moderator Share Posted March 8, 2009 Sorry i dont know, but if it were me i'd be going up just one size jets are cheap and if your up to doing it yourself it'll cost very little...dont expect major difference in power though. You could also consider getting advice from arrow exhausts, see if they have a 'contact us' email address and ask for their advice. Link to comment Share on other sites More sharing options...
