    Did loncin make a dirt bike?

    I have this bike and I think it's a Honda... With a loncin 107 on it. I'd. Like to get new fenders and. Some other parts to get it back in shape. It runs great now but I have no idea what to order parts for. Can you help me Identify it please?


    Also.. On the lonsin... How can I get more cc's? Without changing the crank. Is There a new cylinder and big bore kit that you can buy so the sleeves aren't thin after overbore?

    Trail bikes sells a lot or repro parts for the 1992 Z50. You have a Chinese engine. It might be the 3 valve motor. Check both links for parts.

    As stated above, it is a 3-valve engine, as seen on the tappet cover..

    Not really, you'd be better off getting a new top end kit with a two-valve head that fits the engine stud spacing of the lower end.

    What's the difference? I was told that the engine was bored and it had a high compression piston. I believe it. Bike is really strong for a 107. Not really interested in changing the head for 1hp.

    What you guys think its worth with a new set of fenders and gas tank? (starts on. The first kick every time and doesn't leak at all)

    Well, which is it?

    There's a 99.99% chance that you can't get a new three-valve piston for that engine any more, that's why I suggested a two-valve head to go with a big bore kit
