Hi guys i had a quick question for u raptor pro's since i just bought my first yamaha raptor i dont know if i did good or not, well the story is this. I bought a raptor 660 2001 in phoenix arizona and i live in albuquerque new mexico. when i go trailing and im in a higher gear then im supposed to the bike bogs out like if the engine was getting a lot of gas or somthing. another example is when i pop a wheelie the bike also bogs out and i cant start it within another 8-14 minutes.the last example i have for u guys is that when i try starting my bike the next day or w.e. i have to get pulled by another bike to start the bike, it wont start on its own, the only time it starts on its own is after i get pulled and i stop the bike for whatever reason, and i have to tighten the screw by the motor all the way to be able to start it. and then un tighten it a bit. what does this sound like guys do u think i need to jet it or is IT A BIG PROBLEM AND GOING TO COST ME A LOT OF MONEY =\. THANK YOU GUYS WHO POST A REPLY TRYING TO HELP ME OUT REALLY APPRECIATE IT .
