Hooptiee Posted August 29, 2010 Report Posted August 29, 2010 I just put a new topend in my shee, I had some porting work done and was told I should be around 60 hp, won't be able to get on a dyno until after labor day weekend. My issue is after I am warmed up and am at a idle and just floor it it bogs then takes off, would that indicate being rich on the pilot? I have no room to run for a plug chop can only get into 3rd just barely 4th in my yard. My setup .20 over Ported Hemi head - 21cc domes Toomey T-5 pipes V-force 3 reeds K&N no airbox +4 degree timing Compression 150psi Carbs stock 340 mains Aftermarket needles- clip middle pos. 27.5 pilots Elevation aprox. 850ft Quote
Larry's Shee Posted August 29, 2010 Report Posted August 29, 2010 Are the specs you have listed from before porting or after ? Also what is air screw at ? Quote
Hooptiee Posted August 29, 2010 Author Report Posted August 29, 2010 The specs are after porting the airscrew is 1.5 . with my old cylinders which also had a little porting done only to the exhaust by RDZ no porting on the intake side for some reason, I had a stock head. My jetting was perfect at 300 main, 27.5,middle clip, 1.5 turns. it had 120 psi compression. So the new top end has more porting and a aftermarket head with 21cc domes,and 150 psi. after a 1/2 hour of riding I pulled the plugs they are a light black color not a mocca. but also not a wet black. if I'm at 1/4 throttle and punch it it runs great, but doing a holeshot it has that bog.

06specialedition Posted August 29, 2010 Report Posted August 29, 2010 Who ported your bike? Your builder should be able to get you really damn close. I have an aggresive dune port and I'm running 310 mains. And thats with Cpi pipes. Maybe your "340" main is too big, when you hit the gas your shee chokes on fuel. Just taking a guess. Quote
