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.

  • 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.

Please read my plugs.

Ok. They seem to be burning off some of the black stuff on there. They are defenetly getting cleaner. I only rode it 5 miles. They don't look quite as white and porceileny. More ashed over.

By looking at the new pics it seems I need to put some miles on it and finish burning them clean.

Does turning the pilot screw out, counterclockwise,, make it more rich, or more lean. I just want to make sure I'm going the right way so I don't go too lean and mess things up. :eek:

Are you sure you aren't messing with us here? Aren't these the same pictures from Post #1?
 
GS bikes with the CV carbs (1980-?) tend to be a bit cold natured to begin with, even today my 750 stumbles if I try to ride it just after starting it up. They need to warm up a few minutes. I looked back in the post and you have already removed the seals off the idle screws right.

I actually did a 70 mph plug chop. I went 2 miles,,is that enough. They don't look any different.

BTW. I bet you guys was thinking I was a nut. I said a was going to move my needle a notch. Well, I took a slide out last night,,,and there was no notch's. :eek: I guess that must have been my 38's from my Yamaha XS2.

So I was going to shim the needles just so I could see a change. Do you guys think I should jack with it or not. Thanks. And sorry for the pic oopsy. :D

Hmmm, still looking lean, I would have gone about 6 miles or even further. The motor needs to be at operating temp. Do the plug test again then check. If they still look white then I would probably up the main jets a step or so, not sure I would mess with the needles.

OK. I know I lost credibility when I said I was going up a notch on my needle. :-s But, when I went the 2 miles,, that was just at a steady 70mph. Before that I went through town with a bunch of stop and goes,, then went about 5 miles to get to the 2 mile steady stretch. I beleive it was up to temp. ;)

Just curious why you recommend re-jetting of shimming the needle. Do you think I'm that far off. Thanks
 
A little update.

I shimmed the needle's. I'm using the Radio Shack washer's. I started with 3. The performance was greatly improved. Before it would take a bit to get up to 80mph. Now it jumps right up there. My off idle stumble was almost all gone. Just a touch left. But I know I need to play with the pilot screw's for that. What is puzzling me is by doing my plug chop's,,the plug's look the same.

So today a dropped down to just 2 washer's. I think the performance went down in the mid range. My off idle stumble is a bit worse. Again, I've got to play with the screw's. I just went for a 5 mile steady cruise and did a plug chop. They look the same. It doesn't matter if I do a 70mph chop, or ride it around town and check them when I get home, they always look the same. It seems like nothing is changing the color. They still look too lean I think. Do I dare shim with just one washer. Please advise. Thanks.

What are your idle mixture screws at? If they are 3+ turns out you might need a bigger pilot jet, that is where most of your color is coming from, IMO.
