    I have one on my 640 and the quality is awesome, it's beautiful. And strong.
    I've had one problem with it though, it wore a hole in the bottom of a brand new dry duffle in just 2 days, likewise the previous bag in a few days. It's because it's mostly open space, the bag rests on a very small surface area. I bought a plate of ABS on amazon and cut it to fit, shame to cover it up though. I'm sure it's more of an issue on the 640 because the vibes are pretty bad, but I mentioned it to my neighbor who said the same happened with the PMB on his 690.

    I know there's a giant thread on Thumpertalk about this and I've been perusing but wondering if y'all can give me some from the hip feedback on my jetting. Kinda hard to tell how it's running since I've only run it up and down the driveway but seems to be pretty rich. Starts and idles just fine though.

    Pilot is 45
    Main is 168
    Needle has a red end so I'm assuming a JD? Clip is in the middle
    Air screw is out 1-3/4 turns

    I'll be doing some tuning on Saturday but just looking for some feedback on this as a starting point. Seems to have a hesitation in the mid range. I'm at sea level, more or less.

    It's supposed to be 40 on Saturday so that should lean it out.

    :D

    That is my non-summer jetting. I use a 165 once the temps get to 75+. No clue about JD needle but try a different clip position if you must.

    thanks, I'll give it a try as is on Saturday and maybe raise the clip one notch. Just seemed way fat based on what I had been reading. It's nice how easy the carb is to get to compared to the CRF, just have to get used to fiddling with the carb more often again... Haven't had a two stroke since 2002.

    Well I went to a shop here in town on the off chance that they might have some jets in stock so I can tinker a bit but instead was treated to a rant about how no one rides carbed bikes anymore and you can't hardly even buy jets, everything is FI, the KTM 300 is impossible to tune...etc, etc, etc.

    Our shops around here are terrible...on to Rocky Mountain!

    The codes are not in the factory service manual...Where did you find them?

    I don't have the 300s codes since I don't own a TPI. I carry a list of the 500s codes with me for that bike. Same principle applies though.

    I dont have a TPI either.

    how about the carb version of the 300? does that have any codes to display?

    Id imagine its many less since its such a basic carb bike..curious nonetheless

    Nope, it doesn't need them. It's a 2 stroke and about as simple as your weed eater :-)

    The electric powered weed eater is the environmentally responsible alternative to my $49 Wallmart special, especially when it's running on the pipe early sunday morning spewing out smoke from the premix flavor of the month :D

    I have to admit, I get a chuckle as the little 2 stroke clears out and starts singing like YZ80. For me that's about as good as it gets considering I'm stuck doing yard work instead of out riding. :ricky

    Have you tried the GET ECU and a high compression head on the little bugger?

    Done the GET but left everything else alone. I have about 10 hrs on it, bought it new, just figuring out how to play with the GET settings

    Ha Ha. I was being a smart ass referring to the weed eater..I sure don’t need more power for our slippery NW conditions.

    9259D651-F371-4D3A-ACD6-7945CD377989.jpeg The White Goat is down! Buddy Mike helped repair the broken master link while nursing 2 broken ribs. I had replaced it 50 hours ago but muddy conditions accelerate wear on the thin keeper. Fortunately I didn’t crack the cases in a catastrophic chain jam up. Be sure someone in your party carries a chain press and extra master link.

    I heard it's a requirement and if you run without it you'll only make 1/2 the HP thats available :lol3
