Jetting again and

   l’m running a px125 /malossi 166 ,30mm phbh delorto carb , malossi reed valve kit .At present l’m using a simonini exhaust but woud like a  better exhaust like a rz one or SIP performance pipe, but not sure on jettting was told to use between a 118 -122 does that sound about right…sorry for my ignorance
as l’m new to this!!!

Nice set up you got there bro. Don’t worry yet about what jetting you will need. It will still depend on what pipe will you get and the condition of your engine after you install your pipe. Cheers.

do plug read mate, its the best and you wont get wrong on your jetting. cheers!
