    Has anyone seriously looked into the stem length/TT dimensions for the sake of finding what cartridge forks would theoretically swap over to the SS?

    I suppose the speedo would be an obstacle. Like many upgrades for the sherpa when you look into it far enough you realize it's not worth it....and that may be the case here. But I'd at least like to research it a little.

    I've searched all over the web and haven't yet found someone who has done a swap on the sherpa...but my googling might be off. Anyone know something I don't?

    A guy in Vietnam in this thread swapped his out for some more offroad friendly front forks off a honda IRRC . JDowns swapped his with a Suzuki when he had a mishap in Columbia but dont know the model of that either .

    here it is , 3xu , found the test run with the new forks on it http://advrider.com/forums/showthread.php?p=15826239#post15826239 ...........ETA again; go two pages before that post and he says the forks are off a crf .

    Excellent, thanks. It looks like he says they are CRF forks but doesn't get anymore specific than that.

    Thanks for this information. I was about to order the dr jets, but after reading this I will hold off and see what the end result is. Thanks for doing the testing. I have only had my sherpa for about 200km's, and the carb needs to be cleaned, but the hesitation is pretty bad and I can tell would need to be rejetted. Thanks again!!! Edit: did you also turn your air screw put the recommended 2 3/4 turns?

    I just called and ordered the #40 and #125, tx and all $11.92.

    I see where Mush asked about the air adjustment screw, should I give it some turns while I have the carb off.

    No air screw, but there is an idle mixture screw on the bottom front of the carburetor. There's a brass plug over the screw unless someone's removed it.

    Yes sorry, that is what I meant. Still haven't got all the lingo down properly!!! But the process is well documented on line.

    Ken,
    You've got us all curious! I am still tinkering with the mixture adjustment screw on mine, as I get some rough idle and a surging under low throttle. I've taken the mixture screw down to maybe 1.75 turns out, and it still seems to be running a bit rich. How have you adjusted the mixture with that larger pilot jet? And, have you needed to shim the needle jet as well?

    I had previously rejetted using the Dr Jekle recommended 20 Pilot, 130 Main jets and turned out the mixture screw 2 3/4 turns. When I threw in the 30 Pilot jet, I did not adjust the mixture screw. It might need tweaking later, but for now, it doesn't.

    I will likely be putting in a 35 or 40 Pilot and then seeing how it feels. if it feels a bit rich (it shouldn't) I may tweak the mixture screw/turn it in a bit. (say 1 turn out from seated)

    I will also go down to at least the stock 127.5 main jet and maybe even a 125, to compensate for the larger Pilot/the additional fuel.

    Sounds like you went the wrong way with the mixture screw.

    Try 2.75 turns out, and go farther out (counterclockwise) if it's still surging.

    Turning the screw out = richer, in = leaner.

    It might be worth some effort to try and get a good jetting setup with the snorkel taken off the airbox. You'll probably need to shim the needle in the carb with some washers, but the little playing I did showed some promise as far as mid-range power.

    Hmmm. Had an engine guru tell me it sounded rich to him. Was also getting some afterfire, and that seems to have stopped by going leaner. His instruction was to drop idle speed to bare minimum, turn in and listen for idle to increase; keep going and it will decrease again at which point you come back out a bit - hunt for that middle point. Like I say, it seemed to help with the afterfire, but I haven't found the perfect tool to make that adjustment... and the surging seems about the same.

    Well I'm due for a chain and some sprockets. I've been happy with the stock gearing so I plan in ordering those sizes. The thing is though, I'm planning a trip that will be all pavement with plenty of time spent on the highways.

    So my questions are.

    Has anyone geared up to a 15 in the front? If so, how was the change? Did it drop the rpms at 60ish much and was the low end compromised much?

    If going up one tooth, would this require a longer chain? I would most likely size for the bigger sprocket but I'm unsure if I'd need to order a chain longer for this.

    Lastly. Any suggestions as to where to order these parts?

    Thanks,
    Taehome

    Lots of people talked about that on the yahoo group site. For example, http://autos.groups.yahoo.com/group/Kawasaki-Super-Sherpa/message/12178. In the files section of that group, there is info about where to order... But I didn't see anything current. Short answer: people have done it, the stock length chain should be fine, you'll need to use the adjuster on the rear wheel.

    I was bending some more polycarbonate at lunch again, this time made some wind/rain guards.

    not sure if I will leave them clear or not, if I ever turn loose of the cash and buy a can of the correct green I mite paint some stuff.

    I did notice a tiny bit more wind on the way home, but I will take it over the direct cold winter chill on my hands.

    Those look really nice, 1stgenfarmboy. Great work! I had a KLR650 for a while and the one thing I really liked about was those giant plastic handguards that blocked the wind. Made cold weather riding almost enjoyable.

    What hand guards are those (other than obviously acerbis) and do they go right on without any clearance issues - I really like the look of them.
