I usually agree with you Joe.






But it's a damn good thing you didn't know John Britten.

Its not re-engineering, its only mounting an already engineered part. Size it to the pump/motor, from another with the same cc & your just using more technology / control of the operating parameters of the engine.

Initially yes he was talking about a full re-engineer , but the idea has progressed past that point. & granted it is just an idea , but isn't that the point

John Britten he ain't. I'm pretty sure John Britten would never have even considered using a chain oiler. Don't get me wrong , I can appreciate alternate thinking , but I kind of doubt this guy can check the air in his own tires.

What about a metering pump off a mazda RX7?
You didn't need to drag John Britten into this.

Hoh Jeeze,I about spat ice cream out my nose!!!!!

But no,build a custom alu frame to hold oil,fab up a gear drive for the oil pump off the ignition cover,then run a cable up and attach it to the drivers left butt cheek so as farting can regulate the oil flow...............

There's a point alright,it may be right on top of the original posters head. Not that there's anything wrong with that.

A guy has to start somewhere,maybe next we can all puzzle over converting a 4 stroke to a 2 stroke,and then of course what pump to use?

I think the way to go about retro-ing the injector pump would be just to use one of the older bike ones off of the same size of motor, or possibly something off of an outboard of equivilant cc. The whole reason I asked about pump failures.
The trick with new 2 strokes and DI is they cant be burning or spewing a bunch of oil,the crank bearings need their own closed oil circuit,not as easy as it sounds Ive heard,then the bare minimum has to be mixed into the fuel somehow. They say the sensors involved make it complicated for a 2 stroke.Im hoping KTM comes out with a good one.

Really?

Direct Injection

what about the rod bearing?

Ever consider a snowmobile pump? They have used oil injection right along.... You are serious aren't you?!!!! Of course we already had these pumps once and they were reliable and worked great. They were designed by engineers who knew what they were doing. If you look closely at one that has autolube you will gain some insight into just how difficult retro-fitting would be. Some items like crank bearing and big end required casting paths into the cases.... so you better be a great machinist. Some mfgr really needs to do this again to make the 2 stroke live on as practical.

Thats what Ive been told,a full oil tank goes a long time on one of those direct injection 2 strokes with crank bearings that have their own oil supply.
But it took years to make em reliable on boats and I dont know how the rod bearings get enough lube.

thinking for its own sake

I think this thread should be moved to some assembly required. There are some fine minds there ,and it is THE place for "imagineering" . I have thought about 2 strokes and think that with the correct materials and processes ,a smokeless 2 stroke is possible.
