hey oldsalt,now that you've had the bike for awhile,hows it doin?Do you think its still a good buy?I'm going to buy one but I just like to have your opinion first before I decide.
The motor still fires easily and runs without incident. The engine ran VERY rich as received from the factory. So rich that the little 2-stroke would only run in a "4-stroke" mode at full throttle. After about 20 miles of use I completely gutted the muffler. The damned thing was completely full of stupid tubes and baffles so that the exhaust gasses has to make a double pass down the length! The gutted muffler of course made for better "schavaging" and thereby runs "not-quite-so-rich" at full throttle. I am going to solder up the tiny carb jet and redrill with a slightly smaller size. But that's not really a necessity unless someone else in town gets one and we have to race. It's no longer sloppy rich.
The only thing mechanical that lately showed up to be marginal is the little clamp that holds the chain tention roller. It would not stay put and would allow the chain to get slack. I put a tiny tack weld on the bracket with a MIG and that solved that.
As said before, I fully expected problems with a few inadaquate mounting pieces when I bought it. I wasn't disappointed. Gotta remember that the American importers of such items beat the manufactures down to the lowest dollar. To make a nickle the folks in China have to start cutting corners to provide the merchandise at the lowest price. I'd buy the same engine from the same guy if I had it to do again. The engine its self is just fine. I bought from him, rather than 15 bucks cheaper on eBay, because it came with a 6 month warranty rather than nothing if bought off fleeBay.
If you have any trouble getting yours going just PM me and we'll work out the little kinks.
