ok sorry it took so long to get back on here. Been busy with vacation and race truck. Ok anyway come to find out it was the fuel pump that was getting hot and losing pressure. Got a used one off ebay for $45 (great deal) and it straightened everything out for about maybe 2 months then back to the same ole shit. Going to order a new pump.

And does the 09 have a serviceable filter on the pump?

well i don' t know if tbis helps but in my rc nitro truck once the fuel starts running out the truck becomes more powerful because is running lean, is a nitro engine thing, it also makes it overheat pretty quick.

Back when I had my dead spot at 14,000 rpm it was my coil. And I had a bad idle. I tried the pump first, thats why I have an 09 pump.

Street Hawk- My idle is smooth and short rides the bike does fine. Only when i push it hard and ride a while does it start going down hill. If i stop and turn it off or turn it off going down the road for a few sec (going down the road) it will run great again. I have seen it in cars and trucks pump gets hot vehicle runs bad, seems like the same case to me. Dont know the mileage of the last used pump i put in it but it lasted for awhile.

Asesino- It runs the same when it full or on e. Not having any over heating problems just a lil drop in fuel mileage.
