Julius, that file helpt a lot...
I bought the bike from a colleague, who had taken it apart and couldnt be botherd to rebuild it. Whilst installing the carbs, I managed to route an overflow pipe to the inlet manifold. This caused either a strange vacuum situation, or the engine sucked the float bowl empty and maybe drowned itself in doing so. The inlet manifolds were new and I didnt have the old ones, so I wasnt aware of the rubber blanking plug that should have closed it off.
I think an empty capacitor may have accounted for my no spark situation, I have yet to switch back to the original CDI to see what happens. I have a feeling that the old one is OK. I have one unsolved question concerning the hose connected to the big steel pipe on the right of the YDIS carbs. This rubber pipe leads to a plastic valve, on my XT600 this valve is blocked in both directions, but on the TT600 it is free in both directions. Does anyone know what the correct state is voor this valve..? I think the bike runs better with this blocked and I manged to kick start it for the first time tonight with the valve blocked.
The Bike goes like the wind, I just need to get better at kick starting it...
Ive read all the tips on here and Im using all of them.
