Motor cutting out

[THUNDER]

o3 pitbull, 107ci, runs good, then will start cutting out and dies, let sit 5 minutes and it runs great for about a mile and does the same thing, a friend said it might be getting vapor lock on the tank, has anyone had this problem?, checked all the wiring , coils, spark plugs, it is a low milage bike, 3661, I think it just needs the hell ran out of it, BUT, I can"t keep it running long enough to do so.....

My buddy has an Mastiff and he had same problem you are describing
I know he had to loosen gas cap and hear a vaccum noise when he did this
I think he changed gas cap

Some guys take the vent valve out of the gas cap & no problems.

Yup, take the vent out of the right side cap and you will most likely be good to go. Mine also did the same thing.

Means its winter time I am thinking Cam Sensor it was my problem on my 04. I would have to reseach a little to check out your setup but mine was an easy fix for the non venting cap and the Cam Sensor

i would agree on the sensor and the cap.one more thing i would check is dirt in the tank and carb,my 04 mastiff did something similar,blew out the jets with compressed air,problem solved.good luck and keep us posted

Sounds like a fuel problem, start with the caps and work your way to the carb. Check you bowl then your floats. You might also have some bad gas.
