Hi,
I'm kinda new to this scooter topic, but nevertheless i tuned my scooter a little bit :
I bought a new exhaust for my 101r and my top speed has decreased a little bit from 75km/h to 60 or 65km/h.
Wich rollers do I need to install, heavier or lighter ones? And what are the stock roller weights and measurments of those variator rollers? My spark-plug is nice and brown(as the manual to read plugs said and it listed it as perfect), so do i have to rejet my carb or fine-tune my mix screw?
SO, the main question would be, how can i get my speed back:D?
Thank you for your awnsers ahead!
PS: my english is a bit bad or not-so-up-to-date cause I live in a non-English-speaking country
