I have an 2006 summit X and it runs great. Sometimes when i go up a hill and hit a jump and try and keep goin it bogs a bit but thets about the only time. A friend told me about the adjustable bolts on the secondary clutch which they are set to 1 to chance them to 2 or 3 to bring the rpms up. when i took them out 3 sides were fatter then the one and it wasnt letting me turn them. Do i need to buy new ones? Any other tips or thing i could do?
