Great work and 10 points on the video, any comments on the power vs the standard carb at this stage ?
Good stuff. Keep it up. Why arnt the factories doing this??
Just thought it might be of interest to some people. I goes very well although we are still adjusting the fuel map. Looking to have it at trail blazer this week end for more testing.
Should have this beast there as well, it was the first twostroke I fuel injected, first mechanical then electronic ). Oil is the least of the problems but in this video the kawasaki is running 40 to one on ethanol ( effectively 20 to 1 ratio ) a little smokey but it's only castor and it's like this for safety under testing.
apprantly it has to do with the amount of power (amps) the direct injection requires, they can get it to work on multiple cylinder out board motors, but not on single cylinder bikes, (DI two strokes tend to be only on the bigger outboard motors at this stage)
it was said that Husqy had direct injection two strokes about to be released, I wonder if KTM has brought the rights to this technolgy,
Sthil has released two stroke concrete cutters now, i am not sure if they are direct injection or not,
Wow, looks like a winner, so will this be a retro fit as well as a possible OEM fuel system on new bikes? I know of a certain EXC 250 that might like one. Keep up the good work chaps.
HOW DARE YOU SAY I HAVE A BIG PIPE
Sometimes I ride Slow, sometimes I Ride Quick, But When its Time To Get Busy Out The Hat Comes The Trick.
Epic Events trail ride on Saturday, lots of fun.
EFI twostroke at work.
Does the rotary disc induction help with the fuelling ? I suspect it would as it will be more controlled than a piston/reed valve engine, now anybody got a RG500 engine to test on ?
no, no real difference to fueling / tuning, but the rotary valve engine does have a stronger top end. This engine ( F9 Kawasaki ) features a sliding rotary valve housing. This changes inlet timing as the engine changes rpm so you can have late valve timing ( strong top end ) and yet still have mild timing at low speed for good low down pull ( all the advantages of a reed motor with out the top end gas flow drop off disadvantage). This sliding valve is varied by the computer driving an R1 servo motor. I am slowly building up a new engine to fit into a YZF 250 ( 0010 ). This will be a 350cc EFI, reverse cylinder, reverse rotation crank, variable rotary valve. I'm making the cases so they will fit straight into the alloy frame with no need to cut it.
Awesome man, great job!
First time on a dyno
