I recently bought a kawasaki mojave 250 they did not take care of it. it does not want to shift into 2nd at all, it will but it takes some messing with. have to stop go back to first and try again. it only seems to go when i get the rpms perfect just above idle. also it wont shift to any gear if i rev it till the power kicks in i have to wait for the rpms to goback down, the clutch likes to stick slightly but it doesnt seem to effect it while running / driving does anybody know whats wrong? ive been doing oil changes with proper oil and running sea foam through it and in the crank case. im lost please help. Thank You
