hi all,
2day i tryed adding a new pipe to my otherwise stock aerox. I got this pipe..

I have removed the variater restricter and up untill now the bike got up to 40mph quickly and ran well.

after adding the pipe it seemed like there was no pressure at all and i couldnt get it over 35mph even on a long straight road :S

Can someone explain to me why this is and how i can fix it please

Thanks

Chris

You need lighter rolls and bigger mainjets, maybe about 10 sizes.
The mainjet size is very individual.

thanks for that, can anyone confirm that is the problem?

yes in deed. you need a mainjet around size 80 and rollers someware around 5grams becaus of the increase of revs. the speed on you speedo will be round 50mph. i can't give you the exact figures because every scooter is different so testing which is the best is the only option. good luck
