GS oil eater!

[feelergaugephil]

GS Streetfighter rides mint, I replaced most of everything, I had the bores honed out (lightly) as there was no scores in them.
I checked the rings in the bores before I rebuilt the engine, which showed a gap of .020/.508mm, The gap I figured was ok!
Well, while I thought I was running the GS in i noticed it was using more and more oil, Everytime I went out on it the oil would diminish from the oil window and I was filling up more and more.
No oil leaks anywhere!
I did notice that it was smoking, not bad, but still smoking.
I stripped it all down today, the exhaust outlets were sooty, the exhaust/intake valves sooty/flakey and the pistons very very clean on top and sides (all 4) covered in clean oil.
No carbon on crown of pistons, but combustion area around valves really sooty/flakey.
Only 300 miles since complete rebuild/decoke.
I put the new rings (compression) in the bores and show a gap of .013/.330mm.
I did not check the oil rings, I was told off someone that the oil is getting past the oil rings and past the compression rings.
Further I was told NEVER over lap the the oil ring (squiggly ring) as oil will go past it.
Only 15k on these rings, My question is, if I replace the rings (all 4) will it stop my oil comsumption/smoke, is that gap on new rings OK.
I may have to have it rebored, but that means more $$$$ and waiting period!
I compression checked it about a week ago, they were all over 150.
Let me know guys. Thanks....
OH! I just got my oil sender unit from the Ozzy guy (Sheriffbuckley) it looks awesome, will give you an update on that item when my oil cooler is bolted up.

You didn't mention if you put new oil seals on the valves.

I don't know what you/they mean by overlapping the oil control rings. There are 3 of them, 2 scrapers and an expansion ring. Personally, I don't like the gaps in the scrapers in line with each over. I prefer them overlapped. The expansion ring, when in properly does not overlap itself. I guess that's hard to describe, however, if you need further explanation then maybe you put them in wrong.

Swanny, I believe he is referring to the expansion ring. It is fairly easy to 'overlap' the ends when putting them together.

I assume that you burnt less oil when you first started riding it after the rebuild. You have nothing to loose by giving it a few really hard acceleration runs in a row to bed in the rings if that is the problem. It sounds to me that it is something else but like bores or ring installation or valve seals but try the bed in trick before you tear it down again. Its fun and easy. If you do tear it down again, check your bores with a good ring placed in the bore at different positions. They might be very different at different places causing the rings to actually "pump" oil.

I have a policy NEVER reuse piston rings, always replace them

oil

It has new oil valve seals, thats the 1st thing I did, it is all stripped down now, the new rings (slid in the bores) look better and the gap is a lot smaller than the rings with 15k on them, I guess when I put it together on Thursday, I hope it doesn't smoke with the new rings.
Yes I was refering to the oil scraper rings, I have always overlapped them..

[daveo]

were all the ring-end gaps staggered?

[Guy]

You have to make sure the ends of the wavey ring butt against each other and not overlap. If they overlap they won't hold the oil back. Guaranteed.

Rings

Yes, rings were staggered,

oil

Well, I finally put new rings in it, I checked the gap which was well within spec, I butted up the oil scraper ring and now it runs sooooooo much better, no smoke and not a GS oil eater anymore, Thanks guys for your input.
