HELP!! Using alot of oil recently ???

I would say in the last 2k miles I have added 2 qts of oil? I asked the dealer (my warranty on stage2 was up last week) if it could be burning it pass the piston rings and he said for me to check the sprak plugs. I pulled one off last night and while it had a small amount of black on it I would expect it to be very obvious? Does anyone know of some other checks I can do myself without removing heads and such to determine where it may be going?

My exhaust pipes are very sooty but when it's running you cannot see black smoke or any smoke at all, plus it is running well, no sluggish response, no hesitating or huge backfiring. I do get a small amount of backfire every now and then but nothing ridiculous.

09 RG and I had the 103 upgrade done to it at HD. FYI not related but I am on my 2nd starter since upgrading motor which is now a SE one.

where else could the oil be going if it's not burning and not leaking externally?

Thanks

Transmission?

Have you checked the level of oil in your transmission?
I seem to remember another post where the guy had the same problem.
If that's not it, check the level in the primary too.
It's gotta be going somewhere.
I think if it was burning in the cylinders, you see a good bit of grey smoke, not black.
Good luck! Keep us posted.

One quart in a 1000 miles isn't good, but I don't believe Harley will pull a top end under warranty until consumption is over that level.

Check the Primary pull the derby cover with a drain pan underneath, just in case. Your shifting should be affected if you've got 2 qts extra oil in there, but if it occurs over time you may not realize the change.

For oil to get in the transmission you'd need quite a lot of oil in the Primary first.

Sounds like it could be the umbrella valves in the cylinder heads are not functioning properly. The umbrella valves are part of your crankcase vent system and when not working properly they will dump more oil then normal into the intake and then the engine will burn the oil. Pull your air filter and see if you have oil standing inside the throttle body or if your air filter is oil soaked, you may not see much oil because the oil is sucked into the combustion chambers but there may be some unusual oil build up there.

Make sure when you check your plugs that you focus on the porcelain insulator rather than the firing tip. It should be very light gray to white with no dark colored areas. You said your pipes are "very sooty" which means your running very rich a/f ratios or your burning oil. Wipe your finger on the inside of the pipe, the black should not feel in any way greasy. How many miles are on the motor since the 103 kit was installed?

Thanks, Porcelain tip looks good. There are 10k mi. since the 103 upgrade. I will check tranny and primary this weekend.. I may drop it off at HD and have them troubleshoot it depending on cost. Shifting seems fine as well...I will update..

Dealer found 10% leak by the piston rings, said they never seated. Even though I am 4 weeks past the warranty they replaced the pistons, rings, and cylinders under warranty..Phew..Just hope the starter holds up turning new pistons over now.. I am already on my 2nd one since doing this upgrade.



Ill tell ya this is the last motor I will ever do more than a stage 1 upgrade on.. It has been a nightmare since day 1 and to be honest the power increase is not as much as I thought it would be.

Well bike been running normally since this repair, however noticed on last ride a very louder than normal noise coming from the engine area, at 1st thought it may be a loose exhaust bolts or something.. Just checked oil level and it is absolutely bone dry.

To be honest I did not check oil level after they replaced the rings as I assume they put oil in it and I doubt it would last this long with no oil so that means it is still burning a ton of oil?? ARRGGHHHH

I will call dealer tomorow, is it possible for the level to be bone dry and the oil light to never come on and also the pressure gauge seems to react normally as well?? I wish I had never had this motor opened up...Man this really sucks..

if the motor seems low on power and no oil in resevoir it may be sumping.

How long is "this long" in run hours or miles? Leave the starter out of the post, you not leakin nothin, right? Heat, no one lungin? Blue smoke? Your filter or sensin systems should be kickin in, and motor weak and you can hear noise over pipes?
