    trying to get the threat back on on track (no pun intended)

    Hi TR,
    not planing on replacing the entire front end, just the suspension... i want to keep the original wheel and i assume that the center hub have a specific (and rather small) bearing seat.
    will go with fork brace, as i assume it will be almost impossible to convert the front axial to a thicker one due to a rather small outer diameter of the bearing.

    Hi Tom,
    Got one of these pumps at home from my freeride bicycle riding days, will sure use it, thanks.

    :I say go with 4 and a half pounds of air pressure in each side, and if you can't measure air pressure to within half a pound, you are probably not in the performance motorcycle business.

    Hi TR, guess i have to sell all my bikes and buy a proper pressure gouge that can read half a pound... :-)
    Hi Diamond, will get me one of those as well for the case pressure test.

    have to say, you guys are more than helpfull, and gave me a lot of material to think of.

    :/ the one I carry with me in my fanny pack when I'm riding cost less then 10$ and reads up to 7psi

    … I have no idea why these guys want to make one of the simplest modifications you could ever do, sound so freakin expensive and involve rocket science.

    Here is a little test quiz to see if y'all understand what Pounds per Square Inch means:

    … how many square inches are there in the hole through a Schrader valve ?:I

    Jut to go back a couple of pages, brakes are easy. For sure GS disk rotors are lighter but try a modern disk and feel the difference. I used CBR600 disks on a gt750 hub with SV650 calipers and adapter brackets. http://pinkpossum.com/GT750/phattrakka2/p5brakes.htm They haul that bike down from over 100 per with zero drama and they are light.

    I replaced those caliper brackets with another pair and had alloy adapters machined by a local machinist. And Of course I did not use those stock rubber hoses on the bike. IT has lack braided hoses for a firm feel.

    GT750 forks are OK but can be improved with Gold valves. Not light but they work OK.

    NONE! The hole is a CIRCLE, not a SQUARE!

    What do I win?

    Nothing! The correct answer is .0069 square inches. (you gotta use that pie-r-squared thing)

    I'm not falling for that. Pies are not square either.

    And I should win SOMETHING just for trying! This game sucks. I'm going home.
