air pressure on cb750

[rocks]

Hey guys,

So, I installed my new tires on my CB and they are 110/90/19 for the front and 130/90/18 for the rear.

What will the air pressure be?

Thanks

Depends on your weight but a good starting point is about 31 front and 28 rear.

I agree with Rerun, but I'd consider those pressures to be a minimum.

I read somewhere to run your bike down the highway for 10 minutes and then check your tire pressure. If you've gained more than 2 pounds of pressure that's supposed to indicate extra heat due to under inflation.  1-2 pounds should be optimal.

Wow, that means I am running very low. Just checked it. Tires cold and they were 15psi front 19psi rear.

By the way, I use tubes. Will that change everything

No, tubes won't affect the pressure you need to run. Running low pressure is a really good way to pinch a tube and create a leak. If you notice you are constantly losing air you may have pinched a tube already.

When I had Shinko 712's on my '76F (110 front, 120 rear) I ran 36 front and 34 rear. Worked OK for me,but every tire/bike/rider's weight will need something a little different. But too much air is always better than too little. Just don't exceed the max pressure listed on your sidewall.
