    Any other K-pipe owners out there have a suggestions on tires? While I don't want dirt bike/ trial tires I am coming up with nothing in the dual sport range. I want to stay tubeless.

    I have done a ton of internet searching and haven't come up with much that is OEM size, tubeless, and would hold up to pavement use... I cant even find a spot to order the front stock tire online. I have found some tubeless trials tires but I don't think they would last for much pavement use.

    Shinko 244s may be a option for street knobbies if you have some clearance.. I didn't find your exact size. They're my plan for a small bike I have.

    I kinda wanted to avoid putting tubes in it if I can stay tubeless. I am sure the 3" would work on the front but I am not sure about the 5.10 on the rear...

    After spending some miles on dirt with the stock tires I don't know if dual sport tires would make much of a difference. 125cc 4 stroke has all it can do to spin the stock tire in sand. Knobby tires would make a difference off road but I do enough miles on pavement that they wouldn't last long for my use which is really 75% pavement 25% dirt.

    my concern is keeping speed in corners, oem tires work great on pavement, but I do want something more aggressive

    Any luck finding a more aggressive tubeless that will fit?

    Well the CG200/250 engines are a bit power limited, depending on whether it's a pushrod OHV or OHC. Don't expect more than 15~17 HP. The additional gear is great but with their wide torque range, the gear spread matters more. When you can buy a Honda horizontal clone pitbike engine with a 3.1:1 first gear, the 2.7 first gear doesn't matter so much as how big the spread is from first to fourth or fifth.

    Update:

    I've made a few very simple modification to the K-Pipe that have greatly improved rideability and I would consider almost necessary if I were to purchase another one.

    1. I dropped a tooth on the front sprocket, this made all gears more usable, especially 4th.

    2.I did the ziptie throttle mod. This one is great, considering I have the throttle peg a lot and I have a bum wrist. Also, makes blipping for downshifts much more pleasant.

    3. I extended the lever arm on the shifter to shorten the overall throw. The shifter linkage on these bikes is a poorly designed bandaid that should be revised, this mod made a huge difference in reliably getting into gear, I had some hiccups before hand.

    4: I built a rear rack. This is now my favorite grocery/beer getter.

    Overall, I am extremely pleased with these mods and can't find any downsides, they made a good bike at a great value into a great bike at a great value.

    Planned mods going forward:

    1.Windshield, I have one on order and will be installing this week.

    2. Carb and intake upgrade. These bikes are jetted ridiculously lean from the factory, to the point they barely can idle without coughing to death, and they don't have an adjustable mixture screw. One can remove the block off and modify the carb to be adjustable but I don't like that solution as the carb is already a tiny little restrictive thing that really cuts off the top end. I'm planning a mikuni knockoff in the 22-26mm range. These seem very popular with the 125cc pitbike crowd.

    3.(Maybe) 138cc Big bore kit. I don't really want to start spending big bucks on this unless the carb doesn't wake it up as much as I would like. I will say, I'd like to up the compression no matter what, so this is an option in that regard or going to a thinner head and base gasket. Not sure I want to do a top end job just yet, it only has 1000 miles on it after all :rofl.

    4.(Maybe) performance cam. This will probably happen if I have the head off for the bigbore/compression bump because why the hell not. Cams are so cheap for these motors it's a no brainier, might also consider stiffer valve springs depending on what I find in there.

    Anyway, that's my current take on the K-Pipe. Me and my wife really love it and it can't be beat for the price. Does it need to be tweaked? Yeah. Does it need more power? Duh. Would I buy it again? Absolutely. I don't think there is a better value NEW on the market today.

    Cheers,
    Nate

    Sadly, we won't be here for most of it, we're packing up our RV and re-re-relocating to the PNWet.

    The K-Pipe will be strapped to the front and the guzzi will be hanging on the back (I feel bad for our 47 year old Superior and my wallet feeding it's 440).

    Windshield Update:
    I put on a cheapo 30something dollar eBay windshield today and I must say, I like it!

    Coverage is very good, and after a little fiddling the mounting solution isn't half bad. I was hoping to see a mph or two on top from a better profile but that's not the case.

    Oddly enough, it does feel more stable at speed and seems to hold a line better above 30 mph, must be some downforce/placebo magic going on.

    Looks great! Is this listed as a fit for the K-Pipe or just a universal fit?
