Hi guys. Just purchased another derbi. This time a 2017 model. It's fully stock at the moment. I have a scr corse chrome exhaust on the way. Anyone have this setup? What sort of jetting will be needed roughly?
Happy riding!

i have that it will be around 100 if u remove the restrictor. top speed around 90

Jeah, i think between 95 and 105 for the jet, depending on carb, airbox and cilinder conditions

The bike has only 1000 miles on it

Ooh, then there is no wear and tear. Just start at 105 or so for the jet and work your way down, then you'll be good to go!

Excellent thank you.
