What is the correct front and back tire pressure for a 1990 intruder 1400

From the Clymer

TIRE INFLATION PRESSURE (COLD)
Front 28 rear 32 add 4 for riding double(from the Clymer manual).

Tire inflation pressure for factory equipped tires. Aftermarket tires may require different inflation pressure.

There is usually a sticker on the bike frame by the side cover that recommends the front and rear tire pressure. Regardless, I have found that running 35 pounds front and rear promotes even as well as longer tire wear. The ride may be harder but you also get less cupping on the tires.

were your spacers installed correctly?

Tire pressure is 29 lbs for the front and 36 lbs for the rear

Most bikes is under the seat.

There should be specs on the side wall of the tire for what weight you are loading the bike. normally 36 to 42 lbs

just take the front wheel off and take it to a tire shop and they will usually put it on for like $5. if you dont want to do that you can use a few flathead screwdrivers and take off one side of the tire and then move the tire to the side you just took off and take off the second side. reverse to put new tire on

Maybe, and maybe not. If it is a problem with the master cylinder, then it could be bleeding back into the reservoir.

If it will not pump up and pressurize, and there are no signs of a leak, then you need to look at the master cylinder.

front tire 29 psi back tire 36 psi
