FOR SALE: f3 race bike kr1s / yz490

[Ivan]

many two strokes get there crank and piston lube from the fuel, so full throttle is not really the problem, maximum oil getting in there. The trouble comes when you back off the gas going into corners, the piston is still flying up and down, but there is bugger all oil getting into the crankcase. At least this is the case with dirt bike twostroke engines. thats why most road going twostrokes have oil injection from what i gather.
that rs125 with the 450 is a fourstroke honda crf450 motor if its the one ive seen, and it really hauls. He passed me round the outside, on my cbr600 like i was going backwards, very impressive.
Id say buy this bike because 'dude, 490cc twostroke!!' enough said.

Yes there is a Honda RS125 running a CRF450 engine its red its fast and chews tires lots,

ALso there is the Tigcraft SuperMono ridden by Jason Easton it is not a RS125 it has a custom frame called a Tig Craft which uses 125 GP components it uses RS swing arm forks and Fairings bike is 30mm longer than a RS125 and is designed in the UK

It uses a YZF450 engine very fast

thats why ya run a high idle and a 18:1 - 25:1 pre mix... or if your a really clever bugger...and separate oiler... there are guys in the UK that use KX500 engines in side cars and they have the reliability thing sussed with good horsepower...

more oil = less petrol = less bang = less vroom vroom

But, there is a line. the extra oil can help the ring seal against the barrel, thus boosting compression = bigger bang.

Unless you've got groovy VHM head inserts... they're the shiz..

yeah but to much oil can also be as bad as to little oil,
To much oil gets fouled plugs more smoke
