Okay so im in the processs of breaking in my quad and I think theres a leak but idk forsure. So im going and it starts idleing high when I pulled in the clutch so I stop real fast and I was prolly in 5th gear and I dropped the clutch to kill it so it wouldnt idle high and I heard the gears make like a clashing thump sound, so im like weird? and as im driving it and hit the gas and let go real fast i can here a knock in the motor. So if I hit the gas and let go its like knock and will do it everytime i hit and let go. Someone help me with this POS.
