hi, i was just wondering how to check the pressure in my tire. im pretty new at this and was just curious.
Also, does anyone know the MPG of a 1981 Honda CB400T? just curious.

Ummm, unless I'm really out of the loop, use a tire pressure gauge and stick it on the valve, just like you do on a car tire.

Do you have a tire gauge?
Take a look on the sidewall of your tires. You should find a PSI #.
Press your tire gauge on to the valve and the centre of the gauge will pop up.
Read the #.
My manual says 33psi for the front and rear, but if the bike is loaded, then 36 for the rear.
Some will be more, some will be less.

Actually, you want to take the PSI out of the manual or off the swing arm. The PSI on the tire is the total it can safely hold. On the swingarm or in the use manual is what the manufacturer of the bike thinks is the best possible pressure for riding the bike.

Make sure you get a good seal with the pressure gauge or you won't get an accurate reading. You'll hear air escaping at first, but once you press the gauge down all the way that should stop.

On the tyres that came with the bike. 25 years ago...

Here's a piggyback question. If the swing arm says a higher pressure than the tire indicates, what should you do? I have a strange feeling I don't have quite the right tires for my bike, from a previous owner. ME550 rear and ME330 front on a 750 Nighthawk - '95. The tires indicate lower pressure than what the swing arm suggests.

Heh, just thinking.... When one upgrades tires on a truck, you do a chalk line test (or similar to see the contact patch) to find a good psi.
I guess you can't really do that for a bike, can you?
