i was just saying the sleeve is modded and massive mods sells the mod piston sleeve for this engine for 130 bucks.
I have worked on these engines, I am telling you the caster is not any different by appearance then a standard Go 5 port......They might have adjusted the timing to Caster's Specs, but the visual appearance of the internals it is 100% identical...... FYI timing adjustments make a hell of alot more performance difference then flow mods on a sleeve.... regardless the external modding on the sleeve is standard Go production.... I am going to get some pictures posted and hopefully this will be settled !
