    Was kinda wondering if you'd find a dyno to fit that.
    I've been told. Dreaming`s free.
    Think I'll go, back to sleep.

    Everybody listen, do yours say, what mine says?

    NSR Cylinder Adaptor Plate.jpg

    Posted because someone asked to get a better look at my Honda NSR cylinder to GP100 crankcase adaptor plate.

    NSR GP Cases.jpg NSR Cyl Plate.jpg

    All the original crankcase stud holes are plugged with alloy rod glued and screwed into place. Three of the new studs for the NSR cylinder are fitted into the GP100 crankcase, the fourth is in the adaptor plate.

    I have no idea how big the crankcase volume is, but it is huge, must measure it some day. Long rod, RD400 115mm original is 100mm CC, crank wheels slimmed down and with the gear box spacer plate the flywheels are 12mm further apart than standard.

    Comparison of blowdown area of ported NSR cylinder on the left and standard one on the right.

    Hi all,

    am I right in thinking that an even tubmax would make for easy jetting or is that bs?

    PS - you have a worn out piston available, drill a hole in it.
    that's what I did driiled a hole in a old piston. seems like a also packed modeling clay on the inside of the reed block and then bolted it to the cylinder. might of even packed alittle clay in the exh ports at the bore face so oil cant excape out exh between piston and bore. watch for any air pockets as it will throw off your results

    A couple of heatcyckles more and i´ll se what it produces on the dyno.
    Everythings new in the engine.
    Bearings,crank,cylinder,piston.
    I have ported the cylinder som more also.
    Switch to methanol has been done.

    It has been started since the pic was taken

    nice job there. will you be using standard Kawasaki ign box ? if so can you report back if the best results require the timing plate under the flywheel to be advanced or not ?

    Have you noticed it protrudes into th cyl. just like Jan spoke about a few pages ago?

    And about the short circuiting caused by strangely designed piston that also came up a few pages ago.
    Also encountered this problem with the Gasgas piston.
    Decision was made not to open aux. exhaust pass the holed piston sides.
    Engmod showed enough TA with 193* exh. duration. 72X72 are relatively big numbers, around 9500 rpm at max power with good overrev was the goal.
    im thinking the wiseco ktm300 would be your best bet as far as I know but double check to be sure it will fit your engine. if you notice the front bottom corner in the red circle. the gasgas version might possibly allow a connection from crankcase to exh at tdc so watch for that. this is why I think the ktm version would be more suited. 858M07200 I think is the part #

    But these carbs works best with original airbox with foam filter. Anyway so much modification is needed and not just like change main jet, but with emulsion tube, needle, power jet, etc., because no acceleration.
