Rear sprocket bolts Qingqi QM200GY-BA

[forchetto]

I did some measuring of the holes with the depth probe of a vernier calliper, and mine was just right, but the holes differed slighly and so I tried the bolts on first before torquing up. Mine were just OK, but with tolerances, etc, other bikes might not be and require slight metal removal.

The weather is so crap here at the moment that I still haven't been out to test the new gearing...will report as soon as I can.

My fuel consumption is around 3.1 litres/100 km or something like 76 miles/US gallon, 91 Miles/ UK gallon. I'm not a fast rider though, others may not be as economical.

One important thing to consider with this and all other Suzuki or Suzuki-derived singles up to 250 cc, is to keep an eye on the oil level. The sump only holds about a litre, about the same as a Honda 50 Super Cub, and if the level drops only a bit, lubrication is compromised.
First thing that suffers are the camshaft bearings. Their plain bearings running straight on the cylinder head alloy will start to wear prematurely.

The oil change intervals in my handbook are at 4000 km. I believe this is far too long for such a small quantity and would recommend changing sooner. At about 2000 km. What do others think?.
