Oldfeller, You are right, I previously owned 2 150cc bikes, and got used to them, I just have a year with this one and love it, but as you said, i can avoid the backfire moderating the throttle.
and Justin o guy2, I follow your advice and match the rev sound according to various savage an S40 videos, great tip, the engine is responding better.
bwt When I bought the bike it came with the Jardine, Its cool at first but 112 decibels it is not cool after a 30min ride. I am looking for a stock pipe but have not found one.
Tnx all for your time.
hope next pics are to show you my mods!
