Hi, have you got the exhaust jollymoto 160? If yes, could you be interested in selling me that? Thank you very much. Antonio.

[@zynicss6105]

Do you feel a big difference between 125 and 170cc kit? And what have you put on it other than the cylinder kit?

[@Twostrokesmoke]

There is definitaly a big difference. The power chart becomes much flatter so you have power and torque directly at 6k rpm but doesn't increase much. So i would probably not do it again unless i port it for higher rpm and make a custon expansion champer for it. In this video, I am running a Keihin pwk 30mm carb, Jollymoto expansion chamber (Made for 125cc) and of course the athena 170cc (Not ported) top speed with these mods is 170kp/h and stock is 150kp/h. I ended up putting on the stock cylinder and had much more fun with that as it is much rev happy

[@rednorth7312]

[@Twostrokesmoke]
