i have a sr 125,could anyone tell me how to give my carb an overhaul and how to set it up properly,would it increase the performance,i want to get the best out of the engine,if i have been told that there is a restrictor in the exhaust,is there any way to remove it

not heard anything before about a restrictor, pretty sure the aprilla sr125 is restricted maybe where the confusion came in! try removing the baffle from the exhaust or an alternative air intake?

oh and im expecting the Hanyes Manual through the door anyday, ill get back to you on the carb maintainence

if your bike runs well there is unlikely to be any issues with the carb, as for the exhaust, dunno but check the header pipe hasnt got a washer or smaller tube in the neck

hi kevinsr125 and oldgitonbike,thanks for your help,i"ve got a haynes manual coming next week,going to have a good read of that,im new to biking,but i"ve got the bug!!!!! pretty mechanically minded,so im going to have a go at sorting a few bits to the engine,eg.valve clearanses,the bike runs pretty good for its millage 30,500,but last owner has"nt looked after it,gave it a really deep clean,took wheels off and got em" sparkling!! took me 3 days,lots of rusty spokes!!! i was thinking of fitting a power air filter,would it make a difference and would the carb need adjusting,
