Scooterotica

I'm just about to remove my fuel burner 30mm carb and fit a standard t5 carb on my scoot is a 172 malossi kit with sterling pipe do I need to adjust jets in standard carb to suit set up

122 main jet seems about right with an expadsion or 118 wth a standard pipe. start bigger and work down to these.

Mine needed a 120 main with the standard pipe and a 125 main with a scorpion, with those jets my plug had the perfect colour and I could ride it flat out for long distances without seizing but every scooter is different.

i could not get it to rev with the 120 but perfect with the 118. i even bought a rev counter to see what was going on

i was a bit reluctant to go to 118 though.

same with the taffy, i ran with a 125 for ages and gradualy went down all the way to 120 then back to 122 as i was getting the ebeegebees so wanted it a bit safer.

I use a 125 main on the same set up....3 years so far so good

125 FOR ME AND IVE A Cut crank and matched casings and rubber carb bellow removed
