Looking for some help , my 1000 k2 has poor power through all gears, it starts up fine and runs ok but if i stop and turn the engine of and then back on its back to normal and full power. I dont have any fault codes on the dash, have cleaned the fuel filter,im running a power comander, anybody have any clues?

fault codes via dealer mode? None..

exup valve in exhaust or has that been removed?

The exup valve is tie wrapped to the engine cradle, out of the way.

I had an similar experience with with a later model.. turned out it was crank sensor after i change cam C11 and coil packs C24 +C27..

I also had no Code..

have you changed spark plugs lately? another part that fails without showing a code..

Changed plugs 6 months ago but I will check them again along with crank sensor , cheers

fuel tank breather, probably not with EFI, but worth a thought.

Will check breather cheers. When I re start the engine it runs fine for hours, turning it of and back on seems to re-set it?
