Anyone running a stage 4 WEB cam in thier 300EX

[dirtmomma]

Just wondering if anyone is running a stage 4 WEB cam in thier 300EX & how does it do ????? I just got one, I have a stage 3 in it now but am wondering if I'll loose a TON of bottom end w/ it. I flattrack & they are short tracks till the summer I'm thinking maybe I should wait till then??? I can try it on the trails this winter I suppose but seems like a waste, we may also be running some indoor MX this winter also, Just would like some opinions on this, my set up will be a 75.5mm Wiseco high comp piston,hardened rockers,400 carb w/ 150 main, ported, FMF Megamx full system :) thanks

do you have heavy duty valve springs??

and also how big of a bore is 75.5mm? i have a .060 bore but i forget how many mm it is... i think its around 74-75 but im not sure...

oh by the way i think i have the stage 3 as well and i love it :)

:cool: yeah when we did the stage 3 I really didn't notice a loss in low end just lots more top, I'm thinkin' it might work guess we'll just have to see :)

frosti108 no I don't have heavy duty valve springs.......................yet:D & as for the bore I know that I can only go up to a 76mm piston before needing to re sleeve! My son says it's .040 over????
