  1. Here is a 2 valve head motor,

    GSX crankcase prostock motor.

    At the time 1655cc 18:1 compression 300-350 hp 50mm intake valves 50mm lectrons.

    They now run 1800cc

    The guy who builds these motors Peter Allen built my 1260.

    Not much help but 2 valve porn.

    Cheers Andrew.

    Here is DID chain,

    The best 520 on this chart is,

    DID VM 520 G/B 8050 lbs.

    Maybe the conversion for the JT chains is not correct but again they seem atleast twice as strong as anything else. methinks the conversion is a bit apples and oranges.

    I'll see if I can find a different conversion table.

    Sorry here is the DID list,

    If I am reading these tensile charts correctly,

    RK chain 

    ultra XW ring

    630GSV 11300 LBS/per ft

    520GXW 8800 LBS/per ft

     

    JT chain

    520 HDS 4020 kgf   =  29076 LBS/per ft.

    I have used RK 630 and have been very happy with them, have never used a JT chain but if the tensile strength is accurate they seem VERY strong.

    I'll see if I can find DID brand for tensile strength.

    Cheers Andrew.

  5. Normally baby steps with the pilots too.

    I had the same AFR at idle low 11:1 and went from 37.5 to 35 pilots and that gave me around 12.7:1 or so. Close enough for me as I avoided taking my cabys off like the plague.

    But atleast you have seen a change be it waaay the other scale of AFR.

    The o2 gauge takes alot of the guess work out.

    Cheers Andrew.

  6. Do you know what size your pilot jets are ?

    They will affect your A/F at idle to 3000rpm (they did on my 38 cv) that was roughly where my pilots and mains crossed over.

    I know not all dynos are the same but maybe we can have a dyno off from around the world with the other OSS brothers and sisters.

    Sort of like a dyno world cup.

    With dyno charts posted.

    Cheers Andrew.

    Let me know if this sort of post gets me a warning or ban...

  9. Good tip Ben,

    And I used the '91 GSXR750 hose clamps on the rubber at the carby side as they were a bigger diameter to fit over the 38's. The engine side is standard GSX.

    And the mixture screws are on the underside facing down, I use a cut down screwdriver and most importantly a piece of thickish cardboard that fits on top of the gearbox and around up to the barrel fins to protect your hand when you adjust the mixtures when the engine is warmed up. Fricken hot !!
