Help Needed!!!!

[moorzy1990]

I have an NRG Power air cooled.(2006)

I have installed a 70cc big bore kit and have also brought a leo vince tt hand made exhaust.

If i were to install the exhaust before i up-jet the carb will the bike run ok or is it best to get it re-jetted before i install it.

Thankfull for any advice......

Weather you were to install the cyl or the exhaust you WILL need to rejet either way.. Else say bye bye to your £££. Do some research and you will see any mod to do with volumetric size, carb size, porting / exhausts will all need to be carburated differently.
