    Throttle stuck open - Damage?

    Usually the piston slightly siezes & smears alloy over piston rings, trapping them in place. To check remove exhaust pipe & shine torch up ex port. If lucky a stip & clean up will cure. If unlucky it's ripped the barrel coating and a replate & piston is needed.

    Re packing...

    Well worth re-packing. Do it regularly! Here's a guide I posted about the GG Pro middle silencer. The principles the same. Silencer repack the easy way!

    2011 gasser rear wheel bearings

    Shown as same part number as older Pros ....so it's a 6004 2RS.

    Bearing Numbers

    Fronts are 6905 2RS ...cheap ones from guess where! Shock rose bearing is an odd size & so far only at premium price.

    Carb leaking fuel

    Ignore the drilling. See diagram here: Beta Carb Mod. Just alter float arms/tangs, that does it.

    gas gas 280 or 300

    The forks will loosen up. But I found my 09 GG forks needed some work: I went to 2.5 w oil. And trimmed the plastic spacer (on top of springs) by 5mm. Also tried a different make of fork seal. Now they're pretty good. I tried a Raga & 2011 and the forks seemed fine. But bikes can vary....

    Gas Gas Oil Change

    I tend to use 450cc. ATF is fine. No dipstick, use the sight glass.

    04 Txt280 Blown Head Diagnosis. Need Help.

    Chances are it's smeared the alloy of the piston trapping the rings - so low compression. Remove exhaust pipe & you can prob see this. Iff really lucky a clean up of piston would get it going. If not, plated bore may be damaged, so a piston & re-plate would be needed.

    Gas Gas Gear Change Hesitation

    If it appears to change gear better going up the box than down, or vice versa, then the adjuster behind the clutch could need a tweak. GG USA have a video on youtube showing this. It's a fiddy proceedure, but should cure it.

    Piston For 1999 Txt 321

    Vic, Pistions are available here in the UK. However, you'd almost certainly need to re-plate the bore as well, after 11 years... Normally they re-plate to the new piston spec, and the letter is no longer an issue. Putting a nice new piston into a tired boke can be a false economy. Mike
