My sputtering and lurching at highway speed took 3 trips to the dealer and 4 mechanics to resolve. Turns out it was just a vacuum lock in the gas tank. Now my machine is blazing down the highway.
Damn I am glad it is fixed. I did not talk about it much because I was still riding it everyday to work and having fun since it was only happening at top speeds. I was having troubles getting to 70 miles per hour but now back to 80 if I want it.
I did go down on the jet while diagnosing the problem and it only made things worse until the vacuum problem was fixed. My dealer thought I was full of it. I had to race out of there to get to work and did not have time to talk about the resolution and jet size when I was there.
If you have not been following the story I went from a 122.5 jet to a 135 jet. it ran fine but I was wasting fuel. I knew that the problem was not the jet because it ran fine for months before the stuttering problem began. So I got the valves adjusted and put a better suited jet in. I am not too upset as those things are were necessary and now they are out of the way.
It is just a little frustrating having someone look at you like your nuts and you can tell they just want you to get the hell out of their store. In their defense they did one more pow wow and came up with the vacuum lock scenario and thank goodness because now like I said before, it is fixed and running better than ever. I can appreciate all the modifications now.

44 Tooth Rear Sprocket Installed
Wow. I just had the 44 tooth rear sprocket installed. That is 4 teeth down from stock. I was worried about loosing power but it has werked out great. no notable power loss.
I really like it. I now have a long 4th gear. That is great for around town. I actually sometimes do not realize I am still in 4th gear and anyone who has ridden this machine knows that you are in fifth gear before you can say "God bless America"!
The new custom 44 tooth XF200 rear sprocket brought the rpms at 75 mph down a full 500 rpms to 7,000. not bad for $29.95!!!
I got the valves adjusted and it was needed bad. The high speed stuttering is gone. The mechanics eliminated a fuel issue as the cause and quickly determined the valves needed adjusting. I am definetly going to go back down on the jet as I am dumping too much gas on the plug. It was really black.
I noticed that I am having more fun on the XF200 with the new sprocket. It acts a lot different. Some of the characteristics take a little while to realize. I have had it on for about a week now.
Get one for yourself from JP Motorsports. They have them in stock now!!!

4000 km update
That’s right 4000 km update. I have now discovered that this odometer is reading in kilometers and not miles!!! It only took me 3,999 kilometers to figure this out!!! So at this point 4,000 kilometers = 2,485.48477 miles. So now that we have that straight the bike needs some maintenance.
I am experience pretty significant sputtering when 65 mph or above on the highway. I noticed the hose from the emissions unit going into the air box was disconnected from the air box so I reattached it and it amplified the problem. So I am going to take it in and have the regular scheduled maintenance done.
The problem has started to present itself about 1 month ago. It is getting worse so I have no choice. I have determined that a valve adjustment will be in order.
I am getting some light popping at speed as well from the exhaust. Nothing too severe at all. So I may need to re-jet the carb back down. I went too big when I went from a 122.5 to a 135 jet. Also there is no fuel filter so that will be added as well.
Even with the issues I am still riding it everyday to and from werk. 40 miles = 64.37376 kilometers!! I trust the bike enough to get me there and back.

Free Shipping on the JP/FMF Pipe.
Fantastic news for anyone with a Qlink XF200 or even a Suzuki DR200SE (I think) in the continental United States. Free shipping in the continental U.S. JP Motorsports will ship it out free. So $199.00 plus tax ships it to you free.
The pipe adds a lot of power in my opinion. Of course this is just the "seat of my pants" dyno but its fairly fool proof, just no LCD display! If you have this bike you need this pipe. I am sure you have been looking for one anyways.
I talk more about it below. Just wanted to update the shipping news.

Chapter 9: XF200 JP/FMF Custom Pipe
XF200 custom JP/FMF muffler! This XF200 JP/FMF muffler is specially fabricated by JP Motorsports with permission from FMF! The only place this XF200 JP/FMF slip on exhaust can be purchased is from JP Motorsports. The original Turbine Core 2
pipe that is welded to the the muffler does not mirror up to the stock header pipe. The JP/FMF Turbine Core 2 is two different pipes/mufflers fabricated into one. The XF200 JP/FMF muffler is now available for $199.00.
This specially fabricated XF200 JP/FMF Turbine Core 2 muffler adds a nice power increase! It is a DOT approved silencer with spark arrester. Although not the newest muffler FMF makes, it just so happens it's exactly what a XF200 200cc powerplant needs. In addition to help keep the price down.
Here are the main talking points for the muffler / silencer;
Maintains peak power while retaining spark arrester capabilities
TDS (Turbine Dampening Separator) is a unique baffle design that eliminates the exhaust restriction associated with conventional spark arresters
Originally used by Team Suzuki Off-Road and Team KTM
U.S. Forest Service approved
The only thing you will have to do to get this JP/FMF Turbine Core 2 installed on your XF200 (aside from removing your existing stock muffler) is drill a hole in the provided bracket used to bolt up to your XF200. Then bolt it on. A perfect fit.
Right now, there is no link on the JP Motorsports website to order. You will have to manually pick up the phone and speak to a real live person at 619-564-4935 or toll free at 800-720-1829! You could also email them @ Sales@JPMotorSports.net. I am sure Online ordering will be available as soon as the webmaster for the website can design the webpage!

More XF200 Qlinks In Stock.
The XF200 demand was surpassed in the United States. Now US Qlink dealers have been restocked with the XF200. The shortage lasted only 2 weeks. I was at my dealership this weekend and they had 10 XF200 Qlinks ready to go in all three colors; orange, silver and flat black on the showroom floor and lined up outside on display. Again there were plenty around the world but the demand was surpassed for the American market. So as anticipated this shortage was short lived. Go get yourself one now!

Chapter 8: XF200 Performance Modifications Revised
I have to correct some information previously written about here in the Qlink XF200 blog. I was at the dealer getting my 1000 mile service and was given a lot of good information. First off the 135 jet was too much. The spark plug was grey and if not resolved will burn up the engine. So I will be swapping that out for a smaller size. I did take off the air box lid to get the carb more air but I was told that hurts engine performance as the back pressure is reduced too much. I was advised to put it back on and drill some holes in it instead so that is what I did. Drilled 2 holes in the cover. Will advise if more are needed in the future.
Now for some really, really good news. My dealership, JP Motorsports is working with me to get the Qlink XF200 tuned to optimal performance. They have ordered some pipes to test on the Qlink XF200. That was last week. I am hoping to have a new pipe and correct jetting on the motorcycle next week. Luckily Smitty (the salesman), rides his everyday to work and we are both very interested in the Qlink XF200 being tuned for the highway.
I have swapped out the front sprocket to a 428 16 tooth sprocket. It requires some machining as there are no known 16 tooth front sprockets that will just slip on. Evidently there is a lip on the DRZ200 16 tooth front sprocket that needs to be removed for it to fit on the Qlink XF200 spindle. But there you have it. A front sprocket that werks.
I now can cruise at 80 mph with just that modification alone! The rpms are at 8000 now at 80 mph so at 70 mph are down to about 7300 or so. It did take me a little while to figure out how to ride it after the sprocket swap as It did loose power. I was having trouble getting up to 70 mph until I modified my riding style by just winding up the engine a little more before shifting gears. I was going to go to a 17 tooth sprocket but it won’t fit in the area around the spindle unfortunately. As it turns out I believe any further sprocket mods would be too much power loss although I am considering going to a 45/44 tooth rear. Don't need to right this moment though.
Now it should be pointed out that 80 mph is not achieved sitting straight up. I have to crouch down to reduce wind resistance. I have ridden in some windy conditions and the XF200 is very stable. I know that some people were concerned about that with it being so light and all. I believe the tires have a lot to do with that as enduro tires are thinner among other things.
