Whatsup everyone i just bought my first motorcycle, its a 2006 ninja 250r, had a question and was wondering if someone could help me out. So the bike revs up and accelerates fine in the first 3 gears but when you get into 4th and 5th some times it starts making this grinding noise and dosent want to accelerate and the more gas you give it just grinds harder, is this a clutch problem or could it just be some junk in the carbs?
