FMF Q4 is def louder but is half the weight, meant to give an extra 10% in power and looks far cooler!biggrin

I didn't rejet and the engine was running lean, so it then needed the spark plug hole rethreading and the engine was overheating, then the piston rings went as welldoh Any after consulting the bossman (TTRFan) a new jet was fitted with ease and no further probssmile

 

P.S. I've forgotten what size jet I fitted nowconfuse

I have a recollection that we put in a 150 main. The standard one was 147 and the engine was running very weak.
