medley Posted November 28, 2011 Author Report Share Posted November 28, 2011 Do a compression test, your topend might be getting tired 160 in each cylinder. fresh wiesco crank and .040 pistons. the pistons are still spotless and i can read the part numbers on the top of them and i have the receipt from the shop that did it.

252wheelieking Posted November 28, 2011 Report Share Posted November 28, 2011 (edited) thanks for the info. i have carbon fiber reeds. is dune port good for topend? it kinda feels like my bike falls off on topend and i thought it was the jetting but i guess it is the t-6's. i have spent 2 days playing with jetting,needles and air screws but it's still there. would it help any if i got cpi's right now before porting and ditched the t-6's? Yes a dune port makes good topend. The T-6's are good for a stock motor, if you are going to port it & add alot of bolt on parts T-5's would make a better choice. T-5's are cheaper if you can find a good used set. T-5's run around $250-$300 depending on condition. Yes you would see a difference in CPI's right now from the T-6's with a little jetting. You will lose a little bottomend, but not enough to notice or care about since in return is a strong hit mid to topend. Then get your cylinders dune ported for the CPI's. You will see a big difference in your shee & you will smoke your friends shee if you ride it right.

252wheelieking Posted November 28, 2011 Report Share Posted November 28, 2011 i feel like my bike is down on power too. it doesnt even wheelie going through the gears on pavement and my buddies comes up 1st,2nd and 3rd. i just dont see why his does when the only difference in ours is "race port work" that his has. his bike has lowend too. If it doesn't wheelie on pavement in 1st your jetting has to be off. Your friends shee does it easily because he has port work. That's night & day difference on any 2 stroke. Get the CPI's & have your cylinders dune ported to match your CPI's. Porting is the best dollar you can spend on your shee engine upgrade.

MULEE350 Posted December 1, 2011 Report Share Posted December 1, 2011 What brand compression tester? Makes a differance? Quote Link to comment Share on other sites More sharing options...
FASTOYS Posted December 1, 2011 Report Share Posted December 1, 2011 T5s, Cpis, Shearers, Rockets, will all make much more mid/top end power over T6s even on stock engine. I would try that first and THEN porting if your hungry for more (which you will be as this is an addiction). Bwahahahaaa Quote Link to comment Share on other sites More sharing options...
medley Posted December 1, 2011 Author Report Share Posted December 1, 2011 What brand compression tester? Makes a differance? I will have too look when I get home.
