Hi all,
I've heard that trimming a small 45degree angle on the exhaust side of the piston crown, in line with the exhaust port but not down too far down to the top ring may add some degree of performance.
Whats the verdict on this one?
Where does it add the power (if at all)?
Is this a hit and miss kind of mod?
With the pipe I am currently running power band doesnt come into effect at its best until 30mph with my 36 tooth sprocket even with the long header pipe and long stinger as its a relatively largeish (making up words) pipe. .
While I'm at it whats the best way to mod the fuel cap in order to gain more airflow without making it more likely to leak fuel when I've got a full tank?
Thanks for your thoughts guys.
Cheers
Breno
