I recently bought a 71 Kawasaki G3TR Bushmaster as a project and I'm having a great time with it. It runs but I wanted to take it apart and clean and repaint it anyway so I started last week. Its my first project bike so I've run into a few questions. First, when I took the engine off the frame, a bunch of milky white liquid poured out of it. I read that it could be oil and water mixed together so I went outside and pushed it on its side again and a lot more poured out. (I would guess that around 1/3 -1/2 cup has come out so far.) Is that still a plausible answer? Could that much oil and water be in that tiny two-stroke engine? I can post pics of where its coming out if you need them. Just let me know what would help. Thanks!

 

Welcome to the forum, and nice post in the new member area.

Post some pics. And yes, milky white indicates water in the oil.

 

Here's the engine:


And here's the engine leaking goo:

 

Yes water and oil makes milk

 

Thanks for the responses. I guess I'll just pour it out and clean everything, then hope it doesn't keep making milk. I'll be housing it in a garage so hopefully no water will get in it after this.

I'm sure I'll be back with more questions later!

 

Thanks for the pics, a good flush (kerosene) would be a good thing.

 

Hmm, kerosene you say.. Is that something that has to be done after the bike is all reassembled? I was reading that the bike has to idle for a bit before you can do the flush. And is that the best way to clean out the inside? I'll most likely be replacing the clutch and I know the carb has recently been cleaned. I definitely want to clean it as much as possible - especially after seeing how much gunk was built up on the crankcase.

 

Not really sure actually but this is my thinking of this.

You are correct on the actual running through the gears to do a thorough cleaning. I still would fill up the case with kerosene, shake the engine some and allow the kerosene to hopefully do some preliminary cleaning/lubing. (I have used diesel in the past with good success until the low sulfur requirements were mandated.)
