Hi all!!
I have changed an half sistem to my nc35 (is a localy made, no brand), apart of that is all standard, since then i notice that at lower speed it has lost a lot of power and has lost the brilliant aceleration that used to had, after 5k it seem to revs up fine again.
This bike wasnt sold here in spain so i can get no help, i have been told it need to rejet but i want to have a clear idea before i start touching anything.
I have to say that the exhaust is much more loud than the original one plus it seem to be wide open.
Any ideas of where and what i should start looking at??
Thanks all in advance.

Howdo, can we get a look at your exhaust system please??

What is happening in the airbox? Is it all standard??

It sounds like you need to adjust the pilot screws for your freer flowing system, not replace the main jets.

Try turning them IN (clockwise) one quarter turn.
