Hi Guys

I'm new to the forum as well as the ATV world. Bought my first ATV on Friday Its a 2010 Raptor 250.

one question though. The bike seems stock apart from the DRD box on it. The header pipe looks factory. I removed the spark plug and noticed that was burning grey and not brown.
This tells me its running lean. I haven't checked the Jets yet but they claim they stock jets to. Is it a case of just setting the fueling or will i need to rejet the carb?

Many Thanks
Grant
