    Nice! Just save yourself the time and headaches and get a JD Jet kit. Wish I’d done that from the get go rather than trying to make the factory jets work.

    Thanks guys! I was struggling with getting one this old vs an 08+ but the thing is literally bone stock minus a Fatty pipe. There's something to be said for starting with a clean slate for sure, even if it's been sitting for a while. Hour meter is gone but I estimate less than 50 without a doubt.

    Plus the price was right...I should be under 3k even after adding a bigger tank, skid plate, tubliss and new tires, etc. Can't beat that.

    I'm planning to get it dirty this weekend...can't wait! Need to take the carb apart and see where the jettings at and try to return it to stock. It was idling way high cause he had the screw all the way in, need to double check everything else.

    Without opening a can of worms, he was using 40:1 but I'm considering 50:1. There is a bit of splooge on the silencer and some drops on the fender. Think it definitely needs some jetting adjustments.

    Thanks, didn't see this before I posted. That's probably what I'll end up doing. It runs good but that's only been in the backyard. We'll see this weekend when I can get it on some single track.

    It's geared 13/52. That'll probably need to be toned down...

    But just putting around the yard I'm amazed at the bottom end.

    I run 80:1 with Amsoil Saber and it’s pretty clean.

    If you can't set the idle down with the screw, there's probably a vacuum leak.. check the carb boot for cracks and shoot some wd40 on it while running. If the idle changes when you shoot it on there, there's a leak.

    Oil mix ratio has a big effect on jetting. I suggest you run ethanol free premium or better gas at the factory recommended mix ratio to sort out your fuel mixture issues. 40/1 is way too much oil IMHO. The new TPI bikes run between 60/1 and 100/1 and durability is great. I have never fouled a plug on a KTM running factory mix ratios.

    I'll have to check that...being that it's this old there's bound to be some dry rot here and there. I turned the screw out 2.5ish turns and it idled way down but I definitely need to inspect everything. Only thing I've done is verify the air filter is good.

    Gotcha...ethanol free is all I use in anything with a carb. Our store I believe is 90. We used to run 32:1 Golden Spectro back in my racing days and the silencers were always sploogy. I'll probably start at 50:1 on this beast and go from there.

    Also don't go too far from the truck on 12 yo tires+tubes!
    Sorry if that's overly obvious, but, well, I did it once.

    :D no doubt! They'll be swapped out for Tubliss and some new tires, but probably not before this weekend. I'm on single dad duty for a 2 yo and a 3 month while wife is out of town, so I'll be lucky to simply be able to make up a can of premix before Saturday.

    I was at that ride!!

    What are you going to do with your old trashed pipe? Can I have it?

    Thanks,

    What is the benefit of your custom stacks over the ones that came with the kit?

    I've read that you can remove the pipe, fill it with water, and freeze it. The expanding water will take out the dent. Never tried it and not sure where you're going to find a freezer big enough for a whole pipe.. but it does make sense.

    It works pretty well. Sometimes it takes a couple of freeze thaw cycles though.
