March 31, 200521 yr After reading another post O.A.S mentioned the fuel injected 2 stroke beta! Is there any news/pics/info on this bike or is it myth?
March 31, 200521 yr Author O.A.S motorcycles mentioned it in another thread. Cant seem to find it now tho
March 31, 200521 yr From the rummers we have heard and from some people we know who live in Italy it seems that Beta are taking this different route to get around the 2 stroke ban. Because it is fuel injected you will have a have an oiled crank from a resivoir not from the fuel passing by. Imsuprised you lot don't know more because we heard about this last year i'll see if i can hunt down some more info on it
March 31, 200521 yr Author Cheers O.A.S Im a big fan of the idea of FI 2 strokes! Im hoping some of the MX manufacturers will consider this option too instead of them all going 4 stroke!
March 31, 200521 yr it would still be a two stroke tho wont it? The oil will still get burnt and produce the same gasses james
March 31, 200521 yr Author No you would not need to premix your fuel it would run on neat! The reason you premix is so that the oil in your fuel lubricates the big end etc as it passes it. With a FI 2 stroke you could somehow make the big end run in its own oil and inject neat petrol into the combustion chamber therefore cleaning up the emitions! I thought Gas Gas had played with this idea as well a couple of years ago???
March 31, 200521 yr http://www.popularmechanics.com/science/te...ch/1286526.html That seems like a bloody good idea all it needs now is for a big company to back the idea and get some prototypes built up
March 31, 200521 yr Author Question... how does oil get past the lower ring to lubricate the skirt in that PM engine? Hmmm good question?!?! Edited March 31, 200521 yr by BA Baraccus
March 31, 200521 yr If you really want to know where FI 2 stroke technology is then check out some of the outboard motor sites like Evinrude, Mercury and Yamaha. The technology is there and it does work extreamly well. The outboard manufacturers are well ahead of the motorcycle industry in this field. They are also perfecting 4 stroke technology in outboards too. Mercury even has a supercharged 4 stroke, the Verado, but the darn thing weighs nearly 700 lbs!! Pretty interesting to see what has been developed over the years. They face the same future bans of two strokes as the motorcycle industry but I think their piece of the recreational pie is a bit larger so the R&D money is there and the incentive to clean up two strokes.
