>>> Milky Oil 96 katana 750 <<<

[4EVER1]

I was hoping to get some help with the Katana I just purchased. I believe the bike has been sitting stored for a few years before I got it judging by the rust dust that corroded one of the carbs I replaced. I got the bike running but the new oil I refilled the motor with has turned milky very quickly. Here's my question is it possible this could be a problem from the bike sitting for so long? Here some detailed info of bike it has 5,565 miles, I purchased it on 9-01-12 I got it started for the first time 9-26-12. The chain is pretty rusted and the tags have not been updated since 2009. The motor was also locked when I got it. Thanks!

what did you do to it ? did you do a thorough inspection and service or just change the oil ?

[uncltommy77]

Been that long then needs lots of work. Engine will get condensation over time. Change oil again. You got a list of things. Do a thorough walk through.

Gas overflowing into the crank will also do that.

Through research I did the following
Cleaned and replaced carbs
Put sea foam down spark plug holes
Checked compression 3 cylinders read 150 psi cylinder #4 read 60 psi
Manually turned motor
Drained and replaced oil
Started engine

Bike is now turning engine oil milky really fast
Bike is also blowing white smoke through exhaust pipe and front of engine
I'm thinking engine overhaul is in order

I was thinking engine condensation as well. However is it possible fuel can be mixing with oil?

Gas overflowing into the crank will also do that.

Yeah I'm wondering what's more cost efficient engine overhaul or engine swap?

If it's blowing white smoke, I'm more inclined to go with condensation then fuel in the oil.

Condensation is something that should pass right? I was thinking that the white smoke was do to oil be burned.

This will make it blow white smoke, also could be condensation. Do another oil change and see what it looks and smells like.

If it was burning oil, the smoke would be more blueish in color. White smoke = water/condensation, black = fuel/you're running rich as all get out.

How was the gas tank ? Was it washed out ? // run the bike for a tank and change the oil it might be that week cyl fouling and leaking down .

[4EVER1]

Once again thanks everyone for your time. I will change oil again. I did clean the tank with vinegar, ice, baking soda. Then wd40. If the engine has condensation will that clear up on its own or should i start looking for another engine?

[kevin2502000]

If it truly is condensation, ride it or let it run and see what happens. If you're set on looking for another engine, (which I don't think you need to) you really have nothing to lose.

Great, If it's not broke I don't wanna fix it I will run it for a little while and see what happens. Thanks.

I'm sure once you've got the engine nice and hot a few times it'll be fine. My bike turns its oil milky in damp weather and short runs but clears on a longer jaunt! I wouldn't worry.
