    Do you not venture far out of this thread?? Try looking at his Autopsy thread.
    Don't you look at my accountant.
    He's the only one I've got.

    Caused by the fact that the case "pump" no longer works and the fuel air mixture isnt being transferred thru the ducts.
    If the engine is then leaned up to "fix" the incorrect mixture - then it seizes.
    wobbly, are there any benifits in being able to control air into the crankcase, with this richening phenomenon.

    T250

    Busy rebuilding a T250. I'm battling for tuning info on these. I'm making it std to start with but wanted to know what are the next steps. An upgrade from the 2 transfer ports would be good. Any later models with more ports that are interchangeable would be good.

    Maybe a slot in the cylinder to create a boost port could be an option.

    Lastly any recommendations on which other older 2 stroke forums are worth looking at. I've looked at dozens but not very informative. Lots of individuals have posting of mods.

    PS My motors were 1st 3rd and 4th in the BOB and I can't remember if I worked on 2nd or not. What pity we had no North Islanders there. Scaredy cats !!!

    Cheers Wallace

    Wallace, I think X6/T20/T250s often get filled with Yamaha rods/bearings/pistons, so you might look there. I think with the TD3 they went to square b/s from the 56/50 of the earlier bikes.

    cheers,
    Michael

    Yes, TD3 is 54X54 - I've already told him that Mike Sinclair won a NZ250 title with TD3 barrels on his T20....
    The one he's working on should be left pretty stock IMO. Owner is a social racer....

    engine work

    I think Uniflow was suggesting that at very high rpm - the engine was running harmonically.. all in 'continuous flow'..

    Bit of a bump for this old thread but!

    I'm building a GP100 to take to Bonneville, only going for production records so no big changes. Basically the bike has to appear standard and have the standard venturi size. Other than that you can get away with changing internal parts. Currently I've got a sort of expansion chamber welded into the standard exhaust, barrel ported, rotary valve cut to gp125 spec, standard carb bellmouthed instead of the standard shape. Got a thin spacer under the barrel, barrel skimmed and o ringed.

    Went from 9.6rwhp to around 13.6, have done a couple mods since but would love to get more out of it
