Here are the symptoms. Runs pretty good for about 10 min then progressively starts cutting out. Seems worse between 4,500 and 5800 rpm. 6000 and up is OK. WOT runs very strong. Sled is new to me and has 3600 miles. Motor has 1,000.
here's what I have done. Replaced intake boots, cleaned exhaust valves, replaced exhaust valve bellows and yellow springs. Tried plugging exhaust ports,replaced TPS. reset Tps multiple times. Tried champion and ngk plugs and all look good. Motion pro cable. Changed fuel filter.
fuel pressure was over 100, not sure if that's OK or not.
Reed valves look ok, but ordered some SPI anyway. Do they go bad without chips? There is oil on them, is that normal?
Haven't checked the Stator or flywheel yet cuz sounds like a pita.
I've spent lots of time and money on this and I'm still no closer to getting it running right.
any other ideas or what am I missing?
thanks
Bill
