    yeah it goes 80kph but once the clutch settles in it should go better it only took 6hours to put together it was a ktm replica kids dirt bike got it off ebay 600$ delivered another 400 for a welder couple of u bolts and off i go i need to adjust the expansion chamber i think its blocking the cylinder head from cooling a bit and its a little loud imagine a dirt bike at full revs

    Welcome to the forum (^) Looks like it will keep your bum warm in the winter time.....

    Also keep an eye on the engine mounting brackets. With the power of that engine, you may want to beef them up a bit.

    Nice motor, nice build ;)

    Really cool bike.
    You might do your rear wheel a favor and build a better chain tensioner
    before you pull it into the spokes and lock that wheel up.
    There's plenty of ideas that have already been posted in the past.
    It's not that much fun, especially when going fast.
