Scooterotica

Hi building a 175 engine to put in a chop and was going to put a sterling or scoot rs pipe on it running a jetex carb.Gearbox is Li150 ( remade one ) and 15/46 sprockets and 80 link chain , am i better changing the sprockets?

Cheers

The sterling/scootrs pipes like to rev out a bit... I always worked to a final drive of 5.3 for those pipes

Your setup will provide 5.2. So pretty much spot on.

Stick with what you have and try it.

^ 100% agree

Spoke to Harry Barlow at Pro Porting and i'm going to send top end off to him to get it stage 4 tuned , running with Sterling pipe he's recommending using 16/46 with it but i'll double check with him once he's finished with the top end.

Cheers for the replies

Fair enough but I'd still leave it as 5.2

Did a bit of searching on various forums and thought it would be fine, will check with Harry as maybe he couldn't understand my Scottish accent lol
