- October 06, 2013, 17:42:36 PMUsually, oil in the combustion chamber leaves a lot more garbage than that. I've actually seen the gap bridged and the plug shorted by oil deposits. That looks like it's running a little rich, but not burning oil. Sometimes the additive package in some oils promotes oil loss during the first oil change. Pennzoil is pretty notorious for this problem until the additives build up in the system (or the sludge, your choice). Generally, I do a cold and a warm compression test, as well as a wet one. since you didn't get a huge increase in pressure from dry to wet, I wouldn't suspect a compression ring problem. The oil rings, however, cannot be tested by compression, nor cylinder leak down. Think of them more like squeegee that is supposed to push the oil back down the cylinder walls, not seal in power...I still think you need to monitor the oil usage closely and document the issue. My bike now has over 81,000 on it and has no oil consumption, but I still check it at least once a week.

The plugs.
Can a compression test be done incorrectly?

- October 06, 2013, 16:12:59 PMSounds like the automatic compression release isn't working...manual says 50-85 psi...assuming the compression release is operating correctly. I really don't think that the compression pressures you have point to a problem with oil consumption. What do the plugs look like? Are there deposits on the electrodes? What color are the insulators...

Front cylinder 149 dry, 165 wet
Rear cylinder 125 dry, 140 wet

No point in trying to dyno tune an engine without the box, since that's where they are going to be fiddling with the fuel curve....Keep an eye on the oil usage, maybe the additive package in the amzoil didn't get alone with what was in there before...It's just me, but I check my oil at least once a week. I use a mechanic's mirror so I can sit on the bike and hold it straight and look at the eye...sure wish it had a dip stick.

Have you been using the amzoil right along, or is this something new? I have seen car engines with lots of miles suddenly turn all the ring end gaps so they line up...for no apparent reason. Ring seal doesn't seem to be a problem with these engines. You are running rich, what happened to your fuel mileage? Is it sudden? Vacuum leaks at the MAP sensor and a leaking fuel pressure regulator, or even a stuck open injector could do this
Amsoil from 14k or my first oil change on the bike. I think I remember soot on the fender befor I changed the oil after I bought it.
Fuel mileage is 41.5 mpg on average.
I called three techs today and they all told me I needed a power commander in order for them to dyno tune the bike. I thought aftermarket pipes and a aftermarket air filter would cause the bike to run lean? Would hotter plugs fix or put a band aid over the problem? I mean just to see If I need it dyno'd?

Question. If the bike is running rich, gasoline will dilute the oil. Will the diluted oil pass through the rings and burn out of the tail pipe? Would a tune up fix this problem?
LEAKS.....you might not notice it because of where it is. What kind of oil did you run 5,000 miles?

- September 16, 2013, 20:37:57 PMQuote from: Troll on September 16, 2013, 15:57:22 PMFor what?...Check the vapor drain on the front of the engine, right ahead of the front cylinder. It has a pretty cheesy clamp on it.

The spark plugs have 5k roughly on them and they are dark and smell like gas.

- September 16, 2013, 15:57:22 PMJohn, the Drifters don't have a pog. The trick now is to find out under what circumstances the oil is being used. I have 81,000 on mine and it has 0 oil consumption...You will need someone to follow you and determine if the engine is smoking on acceleration or on decel...Generally, worn rings will cause smoke under power, and valve guides/seals on decel...Check the vapor drain on the front of the engine, right ahead of the front cylinder.

- September 16, 2013, 11:52:14 AMThat sounds as if your oil pump is not working, I thought all the drifters had the POG plastic oil gear replaced but if you have only been doing short runs then just maybe you have got away without doing too much damage if the pump is not working...You should take the bike to a kawasaki shop and ask them to do an oil pressure check..If the pump is not working you are looking at a very expensive repair including total removal of the engine. You can buy a 'Judges' steel gear and a kit with instructions to fit it but expect to pay over $200 for it and if you follow the instructions carefully it might be possible to do the work in about three hours..
