I have a mojave, and i did the rear shock conversion with an 89 250r shock. however the shock is super stiff. even when i adjust the **** all the way to the left to soften it up, it is still super stiff. Its so stiff that when you grab the rear grab bar to pick it up the shock is all the way extended, it has no upward play when you lift up on the grab bar. how would you soften it up
