So does the cooled cases help power? I alwasy head cooler air makes more hp because you hvae a denser more oxygen molecules per volume than heated air.
I have seen the Ultra/STXR/Yamaha PV engines before and I always thought that it wasn't a good design to have the exhaust right by the varbs like that.
Any opinions?
PS A PV 800 SXR engine bored and stroked in my X2 would be sick!
