Why does a motor cough out the Intank ? Can it also be a valve ? I was thinking or maybe spring is to week and valve ain’t closing fast enough?

Great work! Where can I buy the piston rings for raptor 660?

@@p-enduropotoki2966, you have helped me a lot, but I will use your knowledge again if you permit. Still with Raptor 660r (2007, but in Brazil). I have a engine, but I am not sure if it is 2001 or 2002+ (US). I must buy a wrist kit (wrist, bearing and crank pin) They are very similar, but not equal. Wrist and bearing are fitble with all years, but crank pin isnt. There are specific codes. 2001 (3YF-11681-00-00) Weight 1.1875 lb = 538g 2002+ (5KM-11681-00-00) Weight 1.125 lb = 510g The only difference that I have noticed is the Weight, but this is not a good parameter. Do you know how can I be sure if the crank pin is a 2001 or 2002+? Why they are not compatible one another? Thanks!!!

Was your raptor backfiring through the carbs on a cold start?

@Cristian Torres I find my problem my piston skirt was busted and caused piston slap and had to rebuild I threw a big bore kit on and jetted it with genuine mikuni jets and it's starts right up

So the leaking valve caused backfire?

Yes. Leaking valves.

Is there another way to confirm this with motor in?

Yes - but you need a special tool to do leaking test
