    PU does come in handy, but a proper instant gasket is what will be needed.
    I'm not sure what you can get aftermarket that isn't just overpriced black silicon, hence my suggestion of either the Ford or VX stuff.

    So, I will have all my CNC stuff my this Week.

    Only problem is, due to this motorbike mess, I have no money for the frame!

    And I'm going on holiday next week so no building for atleast 3-4 weeks! :(

    Threebond 1194 is what you want. It's the replacement of the product that used to be sold as yamabond/suzukibond (has no lead in it now). Comes in a tube for about 22, apply it with a small brush so it goes on thin. Before you join the cases make sure there are no raised edges from prybar bodgery to hold the case halves apart, as air leaks spell death for 2-strokes.

    The powervalve isn't essential to the running of the bike, in fact some bikes were sold with the valve present but no actuator - the valve was fixed in a pre-set location (the TZR125 was not sold with the actuator as a uk bike in fact). If your piston was damaged then that would be the cause of the very poor power at low revs, the valve just alters the port timing to provide increased drivability down low and high throughput at revs. If you had no valve, you would suffer from poor low down response but not to the level you are describing. Bottom line is - you don't need one for getting about.

    Why do i have to go on holiday now!!

    I also picked up some 1104 three bond instead of the 1194,

    1194 is safer to use as it doesn't use Lead. but i thought, I ride a 2t, I'll live on the edge for a bit :P

    Now, all I need is some electrical wire, a Crap load of Aluminium and I'll be done.

    I really need some spindle mounts, Nema 23 Mounts and Ball screw mounts though......

    yes, I have a sliding Bed design so I only need one, not only that, but the entire cnc will be more rigid and make things better,

    A sliding bed does not mean you only need one ballscrew to drive it. When the cutter is at either limit of the Y-axis travel and cutting parallel to the X-axis the cutting force will create a significant torque on the bed causing it to deflect. How much it deflects depends on the spacing of the bearings supporting the bed, the distance between them and of course the cutting force. Two ballscrews completely eliminates this problem. It's like trying to go round a corner fast in a Reliant Robin...it does work but not as well.
