    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Ugh...I'm just not sure where to go from here...

Well, progress slowed and has apparently come to a stop at this point. I've reached the end of my knowledge here. First off, I'm working with an '82 850GL, with just over 30k on it. Over the winter, I cleaned the carbs and replaced gaskets on the cam cover, head, base, new exhaust gaskets, O-rings, etc...basically, installed an entire new vesarah set. I did NOT do the valve seals etc...as they didn't seem to be an issue all of last year. Anyhoo...now that everything is back together, the bike seems to start great, runs quite well albeit some minor idle issues. However, something is very different, now after running it for maybe fifteen minutes or so, the bike seems to get very very hot and there is quite a bit of blueish smoke escaping from the breather tube and literally fills the air box. I've done a search and found that this is most likely due to the rings, so...I may be done there. But I am curious, why is it running so damn hot, this is different than it ran last year, for sure. I ran it for no more than fifteen minutes today, out for about a mile or so, then ran it back into the garage and it was pinging and ticking like mad and the pipes were hot enough to boil water on contact. I'm not sure if I want to keep going on this project for now, I'm frustrated and just really want to ride. I am considering selling it or doing a part out and seeking out an 1000 or 1100 if I can find one around the area. So, questions, comments and/or flat out offers (lol!) are welcome.
 
hot = lean

hot = lean

I am no expert but I think I read somewhere that if you're running 'lean' it will burn hot...
 
did you download that pdf manual

did you download that pdf manual

that was out there for a bit on the 850? Its the factory manual as opposed to the Clymer...much more info. I downloaded it but I have a 650...helps with the common parts...
 
You've put enough oil in right. Filled it, checked again after turning the engine over 30 seconds or so. Maybe the carbs were clogged letting no air in and now there clean and are running lean.

Are the plugs bright white? Did the floats get disturbed during carb cleaning? Maybe an overly lean condition resulted.

Were the ring end gaps oriented properly?

Could the oil control rings on the piston and spacer been overlapped or bent?

Sometime exhaust manifold gaskets when new need to be retorqued after initially being squished.

How about the cam timing, I flubbed that on once, and rode around awhile before figuring out I was one tooth off.

You may know all this already, but just throwing out a few thoughts/
 
Mybe you accidently somehow plugged an oil journal when you put it back together. The blue smoke out of the breather is an indication along with the pinging of overheating, as I am sure that you have figured out. After checking the condition of the plugs check the compression, for a possible weak cylinder. Smell the oil, if it smells at all burnt, replace it.

How is it running? If the airbox isn't perfectly sealed, it will run like crap and run lean and very hot. Same if the intake o-rings are leaking.
 
If you did not adjust the valves after repalcing gaskets I would seriously consider doing so. I did a similar job a couple of years ago and quite frankly just wanted the job done by the time it was over. The problem I had was too rich not too lean. the valves were all out of adjustment. After I addressed this the dilema was resolved.

Good luck
