Thanks

Sorry my mistake, I was looking at the calibrator jet!

[:D] A 122 is far to big , start with a 112 or a 114

i`ll have to agree with RH, the standard is 110.

Try a 122 main jet.

Vespa… its not just a scooter, its a way of life!

Yeah I must be slipping, need to stay awake more often!

tut tut mtl, lol,.try 118. standard p2, i ran this a last season as sweet as a nut, no probs

Dylan a T5 mk1 has a 120 main jet as standard!

:stuck_out_tongue: A standard T5 main jet is 110 , go to page 70 in your sip catalogue (carburetor tips & tricks) and have a look at si 24/24G which is a carb for a T5 !:stuck_out_tongue:
