where can i get port and polishing

there are a few motor builders on here that can do your port work for you talk to flotek, wild card racing, or kenedy power they are all reputable builders an can help you out with a price based on your needs
 
I got My Cylinder ported at Ken O'Connor Racing. i also sent him my carb, head, and timing plate. He Bored the carb, and did something to the timing plate, and Milled my head.
I ride in the woods and ever since i got the parts back this Machine is amazing! Its got major Bottom and Middle throttle response. This thing rips, I nicknamed it the Wheelie Machine. Total cost 280$
 
allright i wana get a 3+ crankshaft get a port job and the head milled i allready got it bored out 40. over

You likely know this, but just in case you don't, the .40 over bore does diddly for power, and a common misconception is that a .40 over-bore is the same as a 240. The .40 over is just to clean up and true the cylinder from past wear and damage.
 
well b4 i rebuilt it it wouldnt come close to my freinds 350 raptor 6th gear to 6th gear pined but now there nose and nose
 
you should be able to whoop that 350 with a lil work i was killin 350 warriors with just a stock setup an fmf pipe so with a p&p you shouldnt have any problems
