Hi there, i recently bought myself a 2012 Nytro MTX 153" witch a 220hk compressor kit from MPI (i think?) with a GEMS fuel box.
Dno if I need to mention it, but it runs at sealevel in northern Norway.
Problems seemed to arrive quite quickly, i`ve had a testrun for about 5km, then for my next ride when the real snow arrived i got about 1km before the problem showed up.
In the middle of a wheelie i sensed that the power seemed to be fadeing, dropped it down and tried to hit the throttle again, then it started to cut off at around 6000-6500rpm.
The sled cut`s with or without resistance to the belt.
Cold or hot, it starts just fine, seems to run smoothly like it should from 1400-6000rpm but after that it cut`s off, as if you remove the ignition.
It "can" sometimes after driving a short distance stop, when then reduceing to idle after 5-15sek, but then start again just as if nothing was wrong.
I`ve tried replaceing the sparkplugs but with no result.
Checked the wiering for ground sources, the connections for the gems box etc, no positive results.
Anyone that have any suggestion as to why this is happening?
Or even what i can look for?
I`ve got one week before im returning it to the seller (it`s a long drive, that`s why i haven`t done it yet).
Thanks alot for any answers.
