ha talk about another thread takeover but i'm in on this one lol! 1/2A conbat used to be me and my dad's thing... great fun. we had a flying wing factory in the back of our shed cos we kept crashing into each other! I've still a few 1/2A flying wings and a 1.5cc diesel at home. goes fukken hard... who'd of thought a 2.5cc diesel motor can do 160 kph like in this vid. they're mighty spectacular when they collide too

So when the ktm motor finally packs a sad you have a half decent replacement for it then sweet probly go better. Wont cast as much ro maintain.

Obviously a little too technical for some to comprehend...

[barty5]

i know im not barty but - when i pulled mine apart there was about probably a teaspoon full, plus a nice thin even coating on everything

Booms about righht that bout all ive seen your not talkin bout huge amounts enough to coat and bit of resadue much more than that i would be lookin at seals closely.

haha, if its trans oil its red, if its 2t oil its green. simple!

Uh-oh motul 800 is red, i'm too colour coordinated.

OK, little oil in crankcase so no *dipping the big end then (*kezza - your slacking, Freudian door was ajar on that one)

Been reading up a bit more, apparently an important function of 2t lubrication is rust prevention during engine down time, and there's a bit of a trade off with lubrication. Never knew that but obvious now I think about it with air/moisture in mix.

Here's something worth a quick squiz - It's a 2 stroke Jim but not as we know it. NZ design, groovy pivot piston.

lol, i use TTS, always have (since mid 90s), never had an engine fail.

[camchain]

TTS is likely good stuff, and that's a good history. but you know red is fast (the next best thing to orange).

Regarding puddles of oil again, I get a little bit that sits in bottom of my intake boot behind carb. Wondering if reeds are a little worn and getting some blowback? This is just a guess, it's definitely (red) 2t oil, definitely not drool from over-oiled filter. Anyone else get this?

haha planes on a wire we used to make those at school electic ones though flew them in the gym never went that fast though balsa biplanes etc

yea my old 300exc used to do the same thing, i thought it was just fuel mist evaporating and leaving the oil behind

Look at Carb front in the GIF attached to my first post you'll see why?

Ah cool, makes sense now thanks. Mine does that..

[camchain]

mmm I seeee. Bit of blowback pressure going down to BDC. Thought reeds would seal better.
