Bike is burning about 2oz/hr of oil.
97' Tour with recently rebuilt carbs. I am hoping you guys can point me in the most affordable direction for all the consumables...

Gaskets, including the cover gasket (very old) and the valve seals (might as well), valve removal tool, piston rings, lapping compound, exhaust gaskets... Anything else I am missing.


I am VERY poor and barely making bills, I only ride a bike (don't own car), and am looking for the best fastest cheapest parts (lol).


Okay... Thanks..

Might be cheaper and faster to replace the engine.

Have you done a compression and leakdown testing on the cylinders? That might help eliminate cracking the block.  If it's the valve seals, that's more manageable.

the rings could be sticking, for a few reasons,  since these engines don't burn oil.

research http://www.auto-rx-plus.com/ 
many documented great results out there

Steel Cowboy:   I can not afford a motorcycle lift AND an engine. Plus, I am not confident in that level of a task yet. I've only been working on bikes for 3 years, and mostly minor stuff.


Mostly I am trying to see if anyone can help me in sourcing parts for cheaper than OEM Partzilla prices...

I will try to get a compression test done tomorrow. I have a screw in my tire so I took the girlfriend's cage today while I work and will patch it this evening, hopefully. Then I can go get a comp test done, if they are a reasonable charge.

Diagnosis before condemning.  Be sure of the issue. Check everything before rebuilding. My first thoughts are valve guide seals.
  Post your location and there will be help nearby.

Do both Compression and LeakDown.  Each provide valuable information.  While it's nice to buy tools, a leakdown can be done with a compression gauge.  Here's one video that'll show how to do it and explains things nicely.  The basics are to measure how much air leaks over a period of time.  https://www.mobil.com/en/lubricants/for-personal-vehicles/auto-care/vehicle-maintenance/how-to-do-a-leakdown-test

Here's another video showing how it can be done on a motorcycle.  https://www.youtube.com/watch?v=tiza8Zdnvik

I hope that helps!

I know there must be one but I have never heard of a Goldwing format engine needing a “rebuild” as in pistons and rings. It’s very rare or nonexistent. I did hear of a Goldwing here in the Florida panhandle that was burning a lot of oil after Slick 50 (or similar) was added. Somehow the rings got messed up and needed to be replaced. Boom done

Please don't take this as disrespectful, because that's not what it is. You had said you have been working on bikes for 3 years, and mostly minor stuff. I've been working on bikes for almost 49 years now, and I still screw up a lot of crap ! I understand about being poor and not able to afford a jack and stuff. I'm not sure where Lakeland is, but I'm sure there are some good Valk guys near you that could look your bike over and give some advice and help.

I only stated the engine swap because there was one in Texas for $100. And your statement of limited knowledge could cause more damage if not put back together properly.
Timing belts have to be realigned properly or you bend a valve, is what I’m saying
I have a compression gauge too, if you want to borrow it.

check at your local Advance Discount auto parts store. Many of them have a tool loaner program. I think you have put down a deposit but its returned when you bring the tool back. Other stores may offer the same .

The only one I've heard about that has had any head/piston/ring work was Bruce (DDT) and that was at what, 600K or so?

My suggestion?    Buy a bicycle.......or at least a Moped.

If you are "poor"........rebuilding a Valkyrie, is NOT a project you wish to take on.

Godspeed Friend.  Hope you find some wheels............

If you are BURNING 2oz of oil an hour,  You are SCREWED!   Never known the Valkyrie to be two stroke.

NOW if it is just leaking out.....please,  be more specific....... Undecided

Rebuilding a Valk engine (splitting the case and then reassembly) is not the easiest thing to do.

Have you checked the drool tube to see if it needs emptying? Is your clutch working properly? Does the clutch handle come all the way back to the e grip? If the clutch has shed some rivets, the could be blocking the oil return screen in the clutch housing and causing excessive oil consumption.

agrady1995, as already mentioned, but for clarity, post your location in with your profile, so it will be there for everyone to see and know where you are located at.

No one is not wanting to answer your question on where to get inexpensive parts, they are just trying to have you avoid buying and trying to fix something without knowing what needs fixing first, it CAN get very expensive very fast.

This is a continuation of your previous post, the SOS, but that post didn't have too much to do  on the oil issue, was mostly the cards, which sounds like you've licked that problem, and posted about it. Thank you for the follow up.

Oil gets into your cylinders a few ways. The valve stem oil seals, dry and cracked, sucks oil in on the intake.

The rings not sealing. Warn cylinders, so the rings don't wipe the oil off the walls. Or stuck compressed rings, doing the same, not expanding and sealing. There's variations of the above, by they all do the same, let oil into the cylinder.

You also said you have oil burning. When do you see smoke? Acceleration, all the time, or deceleration? Each type points to a different condition.

I'm going on the bike sitting for 5 years (from your previous post in SOS) and a ring compressed and not loose. The compression test and leak down should don't to if and where.

If you can trust a replacement engine, get one close enough for pick up, and a cheap price. This can be done with a floor jack or help from a person, and is actually easy.

I had been in possession of a blown engine, forget what, a piston rod. A post of a head, and another of an engine, but my memory isn't too good anymore, over the last 10 years reading posts. So they likely hood of being a major problem with your bike is very rare, but possible.

We are all waiting patiently on your replies and follow up, wanting to know what's wrong.

Went to go get a impression tester today. None of the local shops have the right size fitting for my plug hole. Did pull all the plugs, though. Number 5 (not firing) and number 2 and 6 have oil in the plug threads, and number 5 has the most.

Still not sure where issue is... I'll update when I can get to the store for the proper tool, hopefully Thursday.

Im going to probably need a leak down tester. Eyed that at harbor freight for 79.95...



As for the comment of a moped, I'd rather shoot myself. Once you go red and black, you don't go back. I have a torque wrench that compares within half a foot-lb of the snap-on one at work, and I can follow a book to replace the head properly. Biggest issue is parts cost, but we'll see what all I need, I guess.

 When I remove the head I will replace the valve seals and put lapping compound on my valves to improve their seal.
If I'm doing this much, is a visual inspection of the rings possible? Manual indicated I could change them without removing engine, I believe.

Look here he offered to loan you a compression gauge and jack for free not the $79.99 that you will spend at HF.
