    Well people ive finally finished the motor, and its mounted in the frame.put the electrics on her and after a whole five kicks she fired right up.I couldnt believe it.and it doesnt even vibrate at all (which was my main concern with this motor) these photos are just after i had it running so the fly wheel cover you can see is only sitting there just to c what it will look like, but other than that it ran perfect i still have a bit of work to do like i only had a stock pipe just rigged up for the test start.reved her a few good hard times and everything went like clockwork.so now i only have to do the foot pegs pipe and chain and all the little things throttle cables etc.but now the hard part is out of the way.that clutch cover in the photos took me so long to fabricate it wasnt funny lol.doesnt look like much but yer it was hard i also put a few pics of my brothers all alloy laydown 200x for those of you who asked to see it cheers

    Mart out of all the years I've been on the forum I think this is definitely in the top 3 coolest things I've ever seen before. Serious props on a job well done. You should send some pictures of it to a few different magazines.

    few more updates people pipe is all tcked together just gotta fully weld it like i said it was more brain pain lol wasnt easiest thing to do cutting and positioning it but its all there now i even made tha silencer run through the middle of the frame nice feature i thought lol. my plans on keeping it stock length are now gone i have to extented the frame 50mm which has to get done to the 200x ones anyway so not to worry but yeh gettin closer now lol cant wait to test ride this baby. i think for the first time ever them throttle govenor screws on the the thumb throttles just may cme in handy lol

    Holy Crap that pipe looks mean on there!!!!!!

    Good job on the motor work, and congrats on the test fire!

    I think when you get done with it, you should send the info and pics into Honda to see what you did to their tiny little bike. They would flip!
