My NEW XF200 qingqi (Pics!)

laurpat,
Welcome to the site.
I have pretty much the same bike (Qlink XF200) with the same can.

It's pretty loud so I stuck a half ass baffle in it.
I currently running a 127.5 main and 35 primary jet.
My mods are documented at

Thank you for the warm welcome. Would anyone have a link where I could get the sprockets. I'm living in Ireland so ill need to get them shipped here. Is it worth putting on a new stainless pipe with the new exhaust . what's this about upgrading the carb? Is it worthwhile. any advise would be great. p

Barnone - Was just going thru your link to china riders. I saw you bought a NFX Helmet. I got a Orange and black AFX Full face too....Bought it from Dennis Kirk. I think I paid about the same $60 I signed up on china riders some time ago but started getting e-mail in chinese and could never figure out how to get logged in, so that site was a wash for me! LOL Just replaced my headlight today, i'll try and get some pics up soon. The black headlight on the orange looks awesome, just like I thought it would. TTYL

Up dating/changing the carb is probably not necessary unless you are going the whole race route with electronics and all that stuff. Not sure it is all that advisable on a chinabike ... but most here suggest you get at least smoother performance through all the gears with a jet change or at least a reset that will balance the flow of the exhaust and inlet after any mods in those areas. Check the threads (search) for specific information when you have a few hours to spare and enjoy the read of many posts.

laurpat,
I don't see the advantage of a stainless pipe over the stock pipe.
Just increased the size of the jets, no replacement of the carb. You might not need to do this depending on the size of your stock jets.

Thanks for the heads up barnone

What is the general opinion on a big bore kit 125 - 150 that is available - http://cgi.ebay.ie/ws/eBayISAPI.dll?...=STRK:MEWAX:IT

If i did this would i need to then look at the Mikuni 30mm Carb?

Here is a link to a 124 that the up-grade was carried out on. http://www.youtube.com/user/darlo31#p/u/1/NkG6YFiaG5s

laurpat,
I see that your bike is only a 125cc, right? I don't know about the 125cc version, mine is 200cc and not very powerful so I think a 150cc upgrade would be a waste of money.
There is not much to be gained in power with mods with these small bikes. Need a lot more displacement to get decent power.

I did some high speed runs(????) with my XF200 to see what mod helps.
First run 127.5 and 35 jets 16 tooth front sprocket Yosh loud ass can
72 MPH indicated

Second run same as first except 15 tooth front sprocket 73 MPH indicated.

Third run same as second run except stock can back on 75 MPH indicated.

Speedometer is off by about 8 percent high according to my GPS so top speed true is about 67 MPH at 8k RPM.

The Q sounds so much better now so I staying with the stock muffler.

So basically, the two mods that everyone is doing to try and get a bit more speed out of this bike are actually making your bike slower?

I get no more than 37mph! Emphathy, pitty, symphathy... something, anything. Well, I won't give up finding parts... I'll try again tomorrow Saturday.
73mph on a 200cc and you're thinking about mods? Good job :D

In some instances, yes. Most of the time its due to tuning. In almost all cases he probably had much more torque with the more free flowing engine. Torque is the seat of your pants acceleration that is much more fun than top speed. What did you buy the bike for? If you said anything but commuting and enjoying the nimble little ride, then you may as well start looking at a larger bike. You will never get anything above 70ish MPH with this little 200cc. The torque is something you should trade for horsey's if u like acceleration and the pull of the bike. Remember that tuning is EVERYTHING in little bikes. Dirty and neglected carbs with lack of valve adjustments will leave you wanting more for sure!

OMG! I can't wait for summer up here in minne-cold-as-hello.
Ttyl everyone.

Felix,
That's my experience but other's may vary.

Also the straight through muffler was too loud and crappy sounding for my taste.

slabo,
The 73 MPH indicated on the Qlink XF200's speedometer is really about 65 MPH according to my GPS.

dirtypickle,
I bought the XF200 to ride in the mountains of North Carolina on two lane curvey roads where handling is a priority and speeds rarely top 60 MPH. The Q does well in that environment. It does poorly on straight high speed highways.

Very true. Highways or windy country roads are completely off-limits. Also I will agree with a strait through pipe of does sound funny. It all depends on the pipe. It pays to get a scooter type muffler and mod it to fit. They are made to resonate and cancel out sounds from smaller engines. Personally, my pipe is strait through and sounds very deep and desireable. Idle isn't loud at all, but it can get somewhat loud under a good throttle slap. :)

I was going to put stainless straight through on with the YOSHIMURA Oval Exhaust Endcan that is pictured in here - Would you advise for or against. Would i be better of with as from factory

Yoshimura muffler on my 2009 Qlink XF200

The Yoshimura can I used was aluminum and the only advantage I found was less weight that the stock pipe. It did not improve the performance of my Qlink XF200 over the stock muffler. It was very loud even with a baffle. Too loud for my taste so I am running the stock muffler.

Waste of money in my case.

Its all about Tue can you choose. There are cans that make loud tinny farty sounds. There are ones that are plain loud and obnoxious. BUT there are cans that sound good; good, meaning that they output a deep roar (like mine). You have to get one that resonates correctly with your bike, and that is the big problem because they usually cost about a bill each time. :(

Good luck on your choice.

Wow ! This bike looks nice. I likes to drive sports bikes & i have drove many sport bikes like Hayabusa, Pcg-600. After watching this bike, i am planning to have short test drive of this bike soon. Thanks for sharing.

What is the normal temp these little bikes are supposed to hover around? Mines rolling around the 210deg [+/- 30deg].

I feel better now, I took all of that emissions stuff off and it seems a little cooler and smoother (that's a word right? smoother-est-ful?...)

Yeppers, The rpms are a little high. My vapor is still not setup correctly, Has anyone put this in? The rmps are very jumpy and wierd. I think I need to figure out the fire-ing config. Most 1cyl. engines fire once per revolution, so that's what I set it to. Maybe I'll find the low-voltage direct connect rather than doing the spark plug wrap-around...

I think this thread would be better off in the enduro section. Either way, Your input is valuable to me.

Thanks for your time,
Greg

Hey dirty pickle, on the fire-ing configuration, the cylinder is fired overy other stroke, thats what 4-stroke means. The piston fires, does a down stroke, up stroke(with no fire), down again, then up and fires. Thats the four strokes. A two stroke fires every time the piston comes up. Just about any motorcycle now is a four stroke, even the motocross bikes. The two strokes are the ones that sound like a chainsaw and burn a mixture of gas and oil.

Too loud is too loud in my book no matter how good some one thinks it sounds.

You're absolutely right!
What I was trying to convey was that the spark plug fires EVERY revolution regardless of combustion or not on most smaller scoots and motorcycles. I does not matter if the spark plug fires on the exhaust cycle as there are no more ignitable particles left.

Sorry bout the craziness.

BTW, I switched back to the 127 jet because I was struggling to stay at 55mph at times, but it is all better now.

Now that my bike is broken in, it is gaining power. I wanna get an oil cooler put in but I have to do some research as to the complications and the places to put said oil cooler.
We'll see I post pictures if its a go

you could mount it like how the 250's oil cooler is mounted
