    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Can anyone suggest the proper inflation F & R on a GS1150 with Battlax bt45's? I am a moderatly aggressive rider if that makes a difference.
 
I run 34 psi front and 38 psi in the rear . If i'm doing a big trip or if Deb's with me , I bump them both up by 2 psi .

Cheers , Simon . :)
 
There's no set pressure. It depends on bike weight, rider weight, road temperature, type of riding, and so on. What you want to see is a 10% increase in hot tire pressures vs cold tire pressures. If you don't see enough increase in pressure you're running too much air and the tires are not coming up to temperature. Too much increase and the tires are too soft and getting too hot. Either way traction isn't optimized and you're wearing out the tires sooner than you should.
 
Yep, follow the 10% rule as Billy Ricks mentioned.

Start with a number that sounds good, and record it so you can look it up. Go for a good ride, about 50 miles should work. Record your pressure as soon as you get back. See if you have your 10% increase. If not, adjust pressure as necessary on the next day, when the tires are cold, go for another ride.

Note that if you carry a passenger, pressures will be different, so you will have to repeat this with the additional weight of the passenger.

Hi,

The 10% rule works out to 32-F/36-R for me and my bike. It will probably be a little different for you and yours.


Thank you for your indulgence,

Thanks to all. I started with the 34F & 38R. Rode hard for 40 miles. Seemed to have grown approximately 10% Only as certain as my gauge is accurate. Handled much better. Was using posted inflation on bike decal. Too low.
