I have recently changed from the normal 2006 cylinder to the athena 2013-2015 cylinder, i saw that the messico racing exhaust i had didnt fit after i changed but the legal one fitted, what unrestricted exhaust fit?
Iam really scared to do anything with the jetting dont want it to be too lean...
has somebody used a the power valve system from 2006 on the 2013.
i bought a athena cylinder for 2013-2015 and thought that it was possible to put in the 2006 powervalve. but now i see that its not possible because it doesnt open all the was and hits the cover when its fully opened.
i thinking...
