Nice luggage rack and top box!

That's a great feeling when it finally starts up; congratulations

I just couldn't help myself......



The Vetter is just so practical and the temp dropped back down to 5 Celsius with possible snow so I guess our winter isn't over yet, and usually not too far behind any snow is rain around here. Took her out for her first run around the block. Ran great, no leaks, no strange noises. So far so good. Sure feels good to have her back on the road, I'll try not to crash her this time around

Hmm,

are you going to stay out of Oregon?

or, are you just going to ride one of your other bikes when you come here?

[azr]

Well....things are not good. I've got blue smoke still coming out of the right side exhaust. I've done the ol' 'Italian tune up' in hopes it would improve things but I still have blue smoke when I throttle it. Nothing on decel. that I can see so at least my seals should be good. The spark plug is showing a bit of wet oil each time I pull the plug as well, the other 3 are dry so I'm guessing my problem is with #4. I'm going to do a compression check and then I guess I'm going back into the engine...again One thing I'm thinking is maybe I put a ring in upside down. Man, what a pain in the backside.

One smoking cylinder

I had this from my no.1:

See thread here: http://www.thegsresources.com/_forum...d.php?t=214108

and smoking video here:

Even the plug looked oily.

I felt that is was something to do with oil getting into that cylinder. But it wasn't.

I was advised to do a carb syn.

Which I did here:

Problem 100% sorted.

Greetings

Ya, I had already done my carb synch, I wished it was that easy. I pulled the engine apart this afternoon. Found the two rings on #4 piston were upside down. The stamped 'R' on both of them was facing down, so I guess that was the issue, if I remember right if the rings are upside down it allows oil to pass..anyone care to confirm that for me? The REAL CRAPPY thing is the base, head and cam cover gasket are toast...arrrrrrr

I think I'm going to go have a couple of beers.....

[landshark]

That sucks man. Drink Beer, Feel Good.

I might hassle you when i start rebuilding my top end

[Charlie G]

Rob,

This isn't inspiring me to fix my 650. Yes beer will help.

Don't worry Charlie, it's just me.... Why do something once when you can do it 3 times. It really is me though, the first time I obviously didn't measure the sleeves properly, this time I put the rings on #4 upside down oh brother..

It all depends on the ring's profile. Are the oil control ring gaps correctly staggered?

Additional gasket set info coming via a PM.

I was actually expecting to see angled rings but these ones are straight at their ends. I did check the stagger and #4 was not staggered properly for some reason, must have moved while it was going into the sleeve. They weren't on top of each other by no means but they were closer together than they're supposed to be.

There can be an angle on the inside edge of the ring allowing the compression to get in between the ring and ring land forcing it outwards against the cylinder wall.

I'm not saying that is the case with your rings, just that it a possibility. It depends on what the ring manufacturers specify.

(I did see the 2nd ring's angle you are speaking of in the service manual)

[azr]

Well, I took the head off, found that I put the rings on #4 upside down fixed that. Put everything back together and she was smoking on a cold start up like crazy. I had left the Z1 Vesrah valve seals in there thinking they would be fine..wrong decision. Pulled the head again and installed new OEM seals






I tell you one thing, I'm getting faster at this that's for sure.



So she's all back together. Unfortunately I haven't resolved the blue smoke on start up, funny thing is she doesn't push blue on WOT or on decel, but I'm done pulling the head for now that's for sure. Couple of other things I did while in there this last time, I put in progressive spring in the forks, world of difference. Bleed all the brakes, now the front aren't nearly as spongy as they were. Also cleaned up the gauges, the original set which was perfect took some damage during the crash so I put in a replacement that actually had a cob web in the lens, found enough parts in the shed to put together a perfect set again, looks way better. I'll put the FM2 fairing back on one of these days, I bought one from a fella in Seattle that is perfect. I tell you, it sure is a nice ride this bike.
