    The oil pump cover is still there, so fairly positive it can be converted back to oil injection with all the requisite internal and external parts, I really would be surprised if Blaster or RD oil pumps/hoses etc would not also fit

    Well, its proven this engine will run on just about any inexpensive premix oil, so if I was DS it Id keep a stash of the tiny 3oz hardware store chainsaw oil bottles in a bag and refill them at home (with even cheaper oil!:lol3). On a long trip, drop into a Home Depot or Walmart and buy more. I think as long as you stay at or below 60:1 with proper jetting its going to be happy enough.

    The few pump problems they had to deal with are now erased from a mfg viewpoint. I ran injection for a good while and the only thing I worried about was a stick pulling off an oil line, which would maybe go unnoticed till it melted the engine. Less complex is more reliable no matter how fast you can or cant ride one. :ricky

    I know the GPX site is a little lacking, but they still show that you can add a '19 TSE to your cart and order it. Maybe there's a few still out there with injection.

    think I would really like the aluminum subframe though.

    I think they've been sold out on anything full sized for awhile. Nearly new ones still pop up used and at good prices, no doubt you could list a WTB on the FB group and get something you could ship, or even ride home! I bet theres enough oil injection parts in boxes of "deleters" to hook ip a new 21.5 in short order.

    Solutions are out there.

    That was really a thing with rotary valve KE and KD's. I took it off both. :gerg

    Now, back to your regularly speculating.

    Question for the collective, my carb still has the "heater" lines hooked up to it, I'm smelling antifreeze while riding and noticing some wetness around the little hoses that go in and out the carb.

    Is there a preferred way of deleting? I was thinking I would just either plug the lines at the head where they go in and out of or maybe just connecting the hose between them. Any advice? The search function of the website isn't very useful

    Should just be a simple union/splice fitting to join the two “heater” (antifreeze) lines that were connected to the carb and just cap off the fittings at the carb.

    Or maybe a bit cleaner/better, pull both hoses all the way back to where they exit the main cooling route, and see if one or the other is long enough to reroute and directly attach where the other hose barb originated

    I used short bolts and one copper washer on each port on the head. The carb pipes can be left open or plugged with some sealer. Ive put some black silicone in them, and one I trimmed them off flush then sealed.

    Leaving a loop of hose is just a potential fail point for no good reason.

    The stinger's heat keeps the calabrese and mortadella warm and supple, like la farfalla de una bellissima giovane donna

    Anyone change your silencer packing? I pulled mine apart because it was getting a little loud, plus all my riding buddies have started to call me “quack quack” because my bike sounds weird, they say it sounds like a duck!

    Anyway, not sure if this was stock, it looks like it was packed with and old mop head. IMG_6782.jpg

    I packed it with FMF 2stroke packing, I bet I saved 3 pounds, I should have weighed it before and after

    Had a weird loop of packing stuffed up in the outlet end

    So you're saying that I shouldn't repack my exhaust with an old mop head?
