I am 150lbs. just picked up a clean 86 Vulcan 750 for $1000 35,000 miles. front forks are too soft and rear is a bit soft also. What setting 1-4 and psi should I set these at, and also my forks. Thank you and happy to be here. Just sold a CB650 to buy my Vulcan. Anyone know of some good straight pipes for these?
