DO NOT IDLE THE ENGINE FOR RUN IN ! Pre heat , start , tune , race.
MASSIVE !
Thank you very much

Forgot to mention that the fuel is also included, 25% bryons.
Would the above shimming and plug still be suitable ?
I've always had good results, fuel consumption wise, with the 2062 (JP4), any views on this pipe ?
0.3mm head clearance is straight out of the box I assume ?
