Bad Bad Smoke

[fabiodriven]

If you are not running the bike through the gears, then it's perfectly safe to do this. Nothing is moving except the crank and it gets lubricated via the fuel.

Certainly do not drive the machine or run it through the gears while in the air either. It's a simple test you run while standing still.

Not true at all. The crank is connected to the clutch with gears and the clutch is connected to the transmisson. Sorry buddy, but if your engine is running, the bottom end is going as well. Look into it. Nothing good can come from running your engine with no tranny oil.

No load, residual oil on the gears. You don't run the engine for half an hour.

I get where you are coming from. But seriously, you aren't going to hurt anything doing a short test. I'm not the only one that recommends this type of test either. I actually learned about it here on this forum.

/shrug Take it with a grain of salt!

i agree, 32:1 for the fuel/oil mix.

as for the no oil in the trans while running it, it is safe as long as you dont run it too long, and you dont drive it.


first, drain the gas, mix some 32:1 and run it around awhile to see if it clears up. if it doent show ANY signs of improvement, then it could definitely be the crank seals.
make sure you get the motor hot, so after mixing the new gas, run it hard for awhile to get the motor and the pipe hot.

Yeah, I guess it would probably be OK. I still wouldn't do it though.

So pull the clutch lever.........

been using klotz 40:1 for 3 years now..Still runs strong as ever..

So pull the clutch lever.........

Everything is still going to spin if you pull the clutch lever just from the natural "drag" in the clutch. You know that that "clunk" when you click it in gear? That is the sound of the gears stopping when they engage. Even if pulling the clutch lever did stop the gears (which it doesn't), the clutch basket would still be turning and your wet clutch would now be engaged "dry". Not to mention the throw out bearing will have pressure on it with no oil on that as well. Just not a great idea no matter how you slice it.

Also the excessive amount of smoke can be caused by the oil in the silencer. I say take the baffle apart and see how it's look.

[Dirtcrasher]

There are other ways of checking this without running the bottom end dry, even for 20 seconds I wouldn't do it and wouldn't advise it.......

I won't say it would cause detrimental damage, but these things spin a hell of allot faster than ya think!

this is great info thread, but where is the guy with the messed up tri-z?

The gears dont spin when the clutch its pulled, assuming the drive line is connected.
I get what your saying though, but for a minute or two its not gonna hurt a thing as long as the engine has been ran recently with oil in it.

The correct way would be to pressure test the crankcase, but draining the oil would be alot easier and faster.

.

If left in neutral the gears will absolutely spin even if you pull the clutch. If you put it in gear and hold the clutch the gears will not spin. Even if you have it in gear so the gears are not spinning, you'll still be doing damage to the clutch.

Like I said before, any way you slice it you're going to do damage.

I think you guys are on the wrong track. He said there was grey sludge in the motor. Grey sludge=water mixed with oil=water is getting in the bottom end somehow. Thats what I would fix first.

[factoryX]

exactly, but he mentioned something else about the gas tank...idk what he was talking about but this thread should stop if the person who made the thread is not responding.

[Meat-BoX]

Gray oils sludge sounds like milky eye/oil syndrome. AKA water leaking into your lower end thus the syndrome. sucks. My Tecate did that, had to do a new impeller seal I believe. I also moved up to GEAR SAVER SAE 75W from Bel-Ray for the engine instead of normal 10w 30 or 40.
