Exhaust can for Qingqi QM200GY (aka Qlink, etc)

[forchetto]

Here's some photos of the "Universal Stainless can" marketed by Xian Racing (UK) fitted to my Qingqi QM200GY-BA.

Apart from the cool looks and errr...robust sound...the main difference is the performance. You will not believe the difference in throttle response, acceleration and general driveability.

This stems from the elimination of the restrictive catalyser insert inside the factory system and associated Secondary air injection gubbins. Up till now I was most dissatisfied with the sluggish throttle response which I put down to the CV-type carb and even considered changing it for a slide-type carb.

No need. The engine now responds instantly to the twistgrip and the rev-counter can't keep up...

These oxidation catalyser systems have been adopted by makers using old-fashioned engines and carbs as a quick, easy and inexpensive measure to comply with European emission regulations, never mind what they do to performance and driveability.

This is a similar situation that the cars of the late 80's had when the primitive catalyser systems knocked off as much as 8 bhp on small European car engines. God knows how much power large American V8's lost. Nowadays well-researched and developed 3-way catalysts, Lambda probes and electronic fuel injection do not have such problems.

You will get all sort of spurious claims for power increases with after-market items such as this exhaust, but in the case of this 200 cc range of bikes I figure the power gained is in the region of 2.6 bhp, that's nearly 15%.

The only other mods have been the increase of main jet from 122.5 to 125 and the slow jet from 32.5 to 35. Suzuki Part numbers for these jets are 09491-25010 and 09492-35008 respectively. If you buy them from a Mikuni dealer, the carb type is a BST28.

The fitting is incredibly simple with virtually no mods required and its stainless steel construction means it will outlast me...

I have been researching about this bike, as I do with all my vehicles, and have found that the South American versions do not have the emissions gear. Everything else remains the same. The quoted power output is 18 bhp. The units destined for the EU only make 15.4 bhp. This is all due to the restrictions imposed by the emission laws.

This is the link for the can. I don't know wether they'll ship abroad, but you could ask (they now will ship abroad, see message number 8). The price is £64.99 which is considerably less than other makes I can think of:
