sleeper06 Posted March 20, 2009 Report Share Posted March 20, 2009 If you have a 90deg tool you can port it yourself,im in long island and will help if you need it.I can drop the ports and ckeck clearances if need be,I have done plenty of strokers.If you want to mix 50/50 you should order 21cc domes cut,tell them 66mm bore,I run 20cc and my comp is 170+ Quote Link to comment Share on other sites More sharing options...

tedd1 Posted March 22, 2009 Report Share Posted March 22, 2009 Run the plate. If you seal it properly, it'll work fine. When you get new cylinders, you can have them ported by a professional. Quote Link to comment Share on other sites More sharing options...
tony cub Posted March 22, 2009 Report Share Posted March 22, 2009 does anyone have port mesurements for a 4 mill stroker i dont need no full dune port i ride mostly woods but i can pin anywere and am i going to have to rejet for this stroker ? what size jets do yous that have it run im at sea level you will have to rejet for that set up..as far as port timings,your not going to get an answer to that..everyone has diffrent mesurements and wont post them up.best thing to do is call one of the builders(i hear FAST is pretty good)and tell them what you want..

yammyboy3 Posted March 24, 2009 Author Report Share Posted March 24, 2009 thanks guys i aprreciate it i think im just goint to take 2 cms off the top of everything Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted March 24, 2009 Report Share Posted March 24, 2009 thanks guys i aprreciate it i think im just goint to take 2 cms off the top of everything I would take it off the bottom of the ports since the piston will fall 2mm farther down in to the bore (running a cut head). If you run the plate it will fall-4mm down the bore and be at the stock deck hight at TDC If your just wanting to mess aound and not worried about messing up a pair of jugs then do it your self. Widen the exhaust port a little. the more you take off the top of the exhaust port the higher the rpm the power is built. Quote Link to comment Share on other sites More sharing options...
ozosborne Posted March 24, 2009 Report Share Posted March 24, 2009 Im running 4mm crank with blaster pistons. I have a pro design cool head with 17cc domes on. They did touch slightly, I just had a base gasket made. As far as I remember the ports lined up perfect. Quote Link to comment Share on other sites More sharing options...
