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?

try your rear at 15 and ride it for a few days at each setting then go up or down in psi
DO NOT USE A AIR COMPR TO CHANGE YOU WILL BLOW THEM!!!
use a bike pump or a lossless air shock pump 30 bucks on ebay

it will depend on your driving style , gear load, your weight, pass weight, terrain
i am 275 and i ride mostly smooth road with minimal gear
so i was at 20 psi on rebound dampener setting 1 but when my wife got on
260 more pounds is was way soft so i went up to 40psi
so now its
solo 40psi setting 1
2up 40psi setting 4

i dont change the air psi cause its easier and i got used to riding at it

Front fork air port?

I have set my rear shocks on 1 and with 15psi ( I ride single and am 160#) Read this link about a front fork port? Can't find where my forks are air assisted. I ride a 1993 VN750-a9

Air adjust forks was only on the first two model years. Max pressure was 7psi I think.

Set your rear at 10% of your weight. If you weigh 150lbs, then try 15psi in each rear shock. Manual says if you weigh under 180 lbs to leave it at atmospheric pressure .....which either means 0 psi or about 14 psi depending on how you inturpet what they mean..;)
(Atmospheric pressure at sea level is about 14.7 psi)

More than likely. yer front springs are shot, or are low on fork oil. But yeah, like knife said, no more than 7 psi....hand pump...

I also have a question about psi and rear wheel setting on a vulcan.

I have a '97 750, i am at about 320# and dont know that much about my bike yet. So far i only ride solo. I am a tall guy, and have some minor back problems.

What would anybody recommend? Thanks in advance on any help i get.
