becareful however you go about it. i have a hunch and its nothing i was able to prove in concrete at the time but i think if the exhaust opening gets to big it causes extreme heat in the topend for some reason. then again maybe im completely wrong on this and i had a isolated circumstance for one reason or anotherlunatic wrote:I really think the biggest restriction is in the exhaust port flange area. Im trying a bigger flange and opening up the flange area to a saber size flange.

might try this guy also http://mccoysperformance.com/about-mccoys.html
That is what I asked for and that is what he gave me. A trial port job. Happy customer.dannygraves wrote: That really clean looking jug would have a lot of people sold on it because its so shiney, but from looking at it, I can tell you thats nothing more than a trail porting job. I can't tell from the pics if any timing mods were done, but there was no major port changes, just a REALLY nice cleanup.

these were a few i had over the last 2.5 years
a stock one i bought and one jerry hall did for me couple years ago, it ran like a scalded dog for what it was

heres one i been tinkering with. exhaust is near 200* on this one

heres another one i been messing with and put quit a bit of time into once i finished it, nothing super radical but should run good for what it is. this was early stages when i started grinding, i ended up removing alot of material from the intake to get it how i wanted. i took some out of the exhaust also but not alot

one thing i see alot of people do that i dont understand: they grind the cylinder to full tilt then use stockish head
. squish is way to big, band is way to wide, angle can be changed also. i think the head is just as important as the cylinder in terms of getting the most from the motor
