p2 scorpion pipe, non lube carb. wat main jet? currently runnin a 118
I was running a 122, but thats all different for each scooter. How is it running? if your plug colour is OK and it runs OK leave it. Backstreet mechanics like myself can take weeks to set up a scoot properly, a professional with dyno would do it in a day…pay the 30-40 quid an hour, it’s worth it.
