Two Stroke Engine Oil Injectors Explained
bicycles reviews | bicycles videos | bicycles online
In this video i teach you how most common two stroke oil injection systems work. These are mostly found in older motorcycles and Enduro dirt bikes.

How do you winterize a 2 stroke bike with an oil injector then?
-
Thanks for the great explanation, should we take it apart for cleaning each year?
Mine is on a 1975 Suzuki GT380, which seems to partial seize after it warms up, it automatically stalls out at that poing, after rocking the bike in gear it frees again.
Any ideas? -
Is there a way to make a pre-mix 2-stroke use normal engine oil?
Even if that involves modifications besides just bolting something on -
so a public service announcement, a 1970's era Suzuki ts185 NEEDS to run on the oil injection pump. as he said, one of those lines run into the bottom of the block, where it properly lubricates the crank bearings. premix will NOT give it enough oil and you'll burn up your engine.

Im sure now if they used these for modern 2 stroke bikes they would redesign them and they would be good.

Thank you for a brief explanation and how does the used or previously injected oil return to its tank? or how the scavenging of used oil takes place? thank you.

So how do you fix the lines?????? The check valve can't be taken apart....
-
Pre-mix oil and injection oil are different and NOT interchangeable
-
thanks for sharing....but we have an old sled that may be pumping too much oil as the brand new plugs go right black, foul up and sled runs rough (when we get it going)...tank level drops faster than we would expect as well.....any ideas?

Walt Junior?

Soooo your saying that the oil pump that is great for people who don't want to premix is the dumbest invention ever because people are to lazy to winterize correctly? im pretty sure that's not the inventors fault. By the way even the brand new snowmobiles have oil inject pumps and they work great.
-
QUESTION... why cant someone inject two stroke oil electronically through an injector?
-
If I just remove the oil tank and plug the hose going to that pump, and premix...will that pump not doing anything hurt the bikes actual engine? I'm stuck and really need some help. Thanks.

Hey mate, Ive got an 83 ts 185 er that started when I bought it, got it home and it wouldn't start, cleaned the carbi meticulously, it has good strong spark, good compression, no air leaks but just wont start unless I put some petrol either in the cylinder or in the back of the carb where the air box attaches. It will run but only until the fuel runs out. float all works and bowl fills fine, pilot jet clear.. I'm going mad?? Any clues?

Thank You! You just solved my problem of fabricating my own. This will be perfect for making my 2 stroke run on propane. A method for controlled oil delivery to the engine has been a problem I've yet to achieve with any high degree of efficiency. My next option to explore was going to be using a Pi or Arduino controlled valve and/or pump for oil injection. This just simplified the whole thing. Thanks my Canadian friend!

WELL DONE, BUDDY.

Well the reason they plug up is because stupid idiots neglect there machine and don't keep up with it and then wonder why there engine blows there's no one else to blame but themselves.
-
Damn good video man
-
Bikes with these pumps shouldnt run on just premix, premix will lubricate the top end but not the bottom.
