I would get a set of shearer inframes instead of the cpis.
From my experience, when i switched over to the shearers I gained
a bit more top end. Also I didnt have any trouble duning my bike
despite what you read here about the shearers not having any bottom
or midrange. And the stingers fit around the air filters better than
the cpis. If you have access to race fuel, you should also get a cool
head and get your builder to recommend you some domes for race fuel.
And lets not forget a timing plate.
A good 4mill duneported engine on race
gas makes a really fun powerplant. :thumbsup:
