    I took the long way to work and the long way back home, a little over 100 kilometers and everything appears to be working fine.



    The first thing I noticed was a small improvement in low end torque compared to the QM200. Overall, it feels the same.... just smoother, with a little more oomph!



    The riding position is pretty neutral, the bars are a little low for my taste, but I think aggressive street riders will like the lower position. The seat is very comfortable compared to the previous one on my 200 dual-sport and the height is perfect for me.



    The brakes are great, the new rear disk is a huge improvement over the old drum style on the QM200 and although the front is only a single disk, it doesn't feel like the bike needs anything more.



    80-100 kph is very smooth, 100-120 kph gets a bit buzzy, I won't give her the GPS top speed test until after the 500 k service. If anyone has the Suzuki TU250 service manual, it would be nice to know the valve clearance to see how it compares to the QingQi. CC, know any QQ people that might have a competent answer for the valve specs?



    Overall, I'm impressed.... it's not a whole new machine, but a nice refined evolution of the original QM200.

    I have a huge list of to-do's and modifications, so I will be dumping a lot of pics and random comments over the next few days. I've been hitting the bike markets for farkles, and QingQi for maintenance specs, so let's get started.

    If something is specific to the QM250, I will point it out, otherwise, most of this stuff is compatible with the QM200 family (motard/dual-sport).

    If you do a lot of off-road riding, you will probably be happy with the stock metal foot-pegs, otherwise, I would highly recommend replacing them with rubber mounted pegs. The vibration difference is quite noticeable, especially if you ride any kind of distance at higher speeds. I found these in the Guangzhou bike market, inexpensive and effective.



    The stock passenger hand rails look good, but are useless when you need to carry something. You can add the rear rack, OEM from QingQi.



    The rack should be simple to mount up, but both of the OEM units I purchased were less than perfect. I few extra washers and spacers and all was well, but I've seen better quality on other racks I purchased from QQ in the past. You can see that it's a little "tweaked".



    Pretty wide tolerance, I added spacers rather than stressing the welds on the rack.



    Installed and ready for (ab)use.



    The stock handlebar position was just too low for me, hands were numb after thirty minutes. I couldn't find a good set of bars with the right combination of height and width, so I grabbed a couple sets of bar risers to experiment. These are 5 CM (1.5 inches) and work fine with the stock cables.



    I mentioned earlier that the rear sprocket is a 520/43T, I wanted to check the front and found it's a 520/15T. The outside cover is a bit different than the QM200, but it still has those annoying little 7mm bolts (should be 8mm like the other covers).



    OEM 520/15T Front Sprocket



    This is a very high quality rubber damped unit that is a rare find on most Chinese bikes.



    The Mikuni carburetor is a little different than the QM200, notice the new choke lever and the push-pull throttle linkage has been replaced with a single pull-type.

    That's all for now. The new dual-sport rims and tires (21" & 18") just arrived so I'm off to the garage for more wrenching.... stay tuned.






    On the new QM250 engine, the cam chain and spark plug are now switched, but the stator and clutch remain in the same positions.



    The bike came standard with an NGK DR8EA spark plug. Mine was a bit white, which confirms my suspicion the bike runs a little lean, probably for emissions.

    It didn't look good. For some reason, the top end was starved for oil and most of the parts were pretty cooked.



    I fired off an email to QingQi with all the details. They were as surprised as I was and asked me to dig deeper into the oil pump to look for clues. So off with the side cover to get a better look, the oil pump system is hidden behind the clutch.



    The first thing I did was look back through my old photos of the QM200 as I remembered the oil pump was driven with a metal gear directly off the crank.



    The new system of the QM250 uses the same Mikuni oil pump as the QM200, but it's driven from the back of the clutch. The gear is made of a very lightweight "plastic" material. It looks like a PA66 resin, but it could also be Stanyl. Manufacturers use this type of gear to reduce weight, cost and noise. Under most circumstances I think the gears would be fine, but I remember the 87-99 Kawasaki Vulcan 1500 had some issues with the same type of gear. Mine looked OK, but I then noticed some small plastic shavings in the oil.



    On the back of the clutch, the gear in the middle was not making good contact with the plastic gear.



    Over time, the plastic was slowly shaved off and eventually the gear was barely making contact. I tried to rotate it with my finger, sometimes they would catch and sometimes it would slip. Here you can see the damage inflicted on the plastic.



    Again I fired off an email to QingQi with my opinion of the problem. They felt it best to send the engine back to Jinan for further evaluation and I agreed. A few days later I received a call confirming my findings. They asked if I wanted to rebuild the motor or wait for a new one. New sounded good, but it would be a few weeks to make that happen so I put the project on the back burner. Although I was disappointed with the failure, there is no way I would say it's indicative of a major problem with the QM250. The bike is not yet in serial production and mine is one of the very first QM250's QingQi built for testing and showcasing. I personally saw test bikes sporting this motor in Jinan with well over twenty thousand kilometers, so in my case it could have just been bad luck. Time will tell, as I obviously will be checking the wear on this gear in the new engine.

    A few weeks passed and eventually a big box arrived at my office. I opened it up and pulled out the new motor. The folks at QingQi made sure everything from the carb clamp to the sprocket was already in place and ready for a quick install. Here it is before getting started.



    Everything set up, this should be easy, right?



    The difficult part is getting the frame and swing arm pivot to line up here.

    Once you get the first bolt in, the rest is pretty easy. I marked the frame mounting areas with letters and the various screws with numbers. A&D are the main load points for the engine followed by B&C. Letter E is just there to protect the bottom of the engine and provides mounting for the skid plate.



    And here is a view from the other side



    Once the engine was in, everything else was pretty easy and it only took about an hour to get the rest of the parts back on. The bike really is a joy to work on because it's so simple and doesn't require any special tools. All things said, I'm glad I went through this as it's always nice to learn a little more about your bike, could come in handy out there in the wild .

    Sometimes, bad things happen to good motorcycles. In this case, I really think the people at QingQi deserve a bit of praise for the way they handled the situation. They asked how I wanted the issue resolved and allowed me to decide on how to proceed. I chose to do my own labor and some extra goodies were shipped with the engine to compensate for my time and effort. Although it did take some time, they delivered on everything that was promised and I'm happily motoring down the road again. Thanks QingQi (specifically mister j)

    Oh... and about those goodies... looking pretty good as a dual sport (new shock and 21" / 18" wheels)
