    Every day now it seems like there is a new problem and more money and time that has to be dished out just to get this thing to go another few miles.... at first it was cool and fun , but I'm trying to have some sort of reliable transportation ... I can't afford new parts every week ... what started out as a $250 project has probable gotten closer to $800.00 by now and climbing ... maybe I should just save up and get an actual motorcycle that will last 100,000 miles

    Some people have great luck with the 2-strokes, and some don't. Only 2 of my own 5 2-strokes lasted over 1,000 miles. I use my MaB as my main transportation, so I ditched the 2-strokes and went 4-stroke instead. Has a little less power, but much smoother and cheaper to run.

    Sorry to hear that...Out of 6 builds I've had 2 problems...CDI defective in 3 days after instillation, and a blown head gasket. All on the first build. Since I've made the (inexpensive) mods...Nothing has gone wrong. Almost 2 years now. Not so much as a flat tire.

    What kind of engine is it? I've had a 2-stroke from Dax. It's been about as close to trouble free as any engine I've ever had, in any vehicle I've ever owned. I'm not sure where Dax gets 'em but I bought mine there just because he's one of our vendors who had really good customer service reviews.

    You weren't specific on what kind of problems you're having. Tell us what your failures are and maybe we can help eliminate some of them for you. What kind of "parts" are you replacing? Give us some information.

    basically the large gear on the right side felt a bit loose yesterday and was causing the engine to rattle a lot ( I finally got it running again ) . I decided to take the bike for a little ride around the block to listen to the sound and in less than 2 minutes of riding the engine siezed and the back tire instantly went into a skid. Last time the engine siezed I heard the rattling but couldn't pinpoint where it was coming from but now I'm positive it was coming from the large gear on the right side. I had the engine open minus splitting the case and didn't see any signs of visible damage so I just put it back together . I'm really not sure what it is other than the gears at this point... thoughts ?

    I had LOTS of problems the 6 first month of use.
    But on the last 7 month i only had really easy solution problems, and i really dont give lots of mantainance to the bike, and i ride it everyday, and it still moves better than the first day.
    Good luck!

    You guys have amazing patience, you really do.

    The first time my motor locks up and skids the tire is the time it's going into the trash can. I'm 56 and I don't want to die because of a POS China motor.

    Did you check the other side, where the chain is? Sounds more like the chain was bunching up in the clutch actuator cover do to improper chain tension. I've never heard of the primary gears binding.
    Are you checking the chain tension and alignment? Did you lubricate the gears?

    There are other engines besides the China made 2 strokes, of course. I've had great luck with Japanese made engines.

    That said, I've no license issues so I picked up a '95 Honda 250 Enduro for $800, all it needed was a little maintenance and cleaning, starts on the first try.

    I have had no problems with the engine itself, most of my problems were install related, sprocket alignment loose tensioner, etc. I locked up my rear wheel more than once, but it was never the engine.

    If you do an extensive archive search on this and other motorbike messageboards about engine reliability you will find that the concenses is that the Honda and Sabura 4 stroke are leading the way if reliability is one of your highest priorities. If cost, power, or weight is a higher factor than the answer changes.................Don

    i had issue after issue with my skyhawk engine. i just got a brand new one from the guy a bought my first one for and the first problem i had was the pedals locking up. i'm getting that worked on.. unfortunately i don't have the tools or know how to fix even the easiest of problems. i really really wish i would have found this forum, and knew some people who owned motor bikes BEFORE i spent my last bit of savings on one. i too, was planning on using mine as regular transportation

    Mike,
    You've aged very well. Your avatar made me think you were much younger :)

    That's me at age 10.

    I found that pic when I was going through all the stuff in the house before I sold it. After Ma died, pops lived there for 2 years, then deceided he wanted to live with us out here in CA. He got sick every winter in Detroit.

    That was a busy time.
