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.

Tom

have you any other ideas as it is a slow bike

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.

would you now what difference it would make

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.

cheers mate i will
