Well since I can't get to you what kind of bugs? Maybe we can help you sort it out and get you riding.

Too nice a little ride to be sitting around.

cheers,

have no idea how to tune the carbs and start from scratch. idles a little high when it starts. smokes a little white smoke when it runs but runs smooth

Hi Mr. strangelinc,

Your bike looks nice. Good work on the custom body parts.

There is a lot of work ahead for you, cleaning carbs, adjusting valves, fixing the charging system, etc. You must avoid these: Top 10 Newbie Mistakes. You'll find "how to" guides for most of the general maintenance tasks on my little website. Here is what you need to get started:

Here is your very own magical, mystical, mythical, mind-expanding "mega-welcome". Please take notice of the "Top 10 Common Issues", "Top 15 Tips For GS Happiness", the Carb Cleanup Series, and the Stator Papers.

P.S. In case you haven't noticed, this is the 2 cylinder section. You have a four cylinder engine.

If the choke is ON then it's normal for the RPM's to rise, this is how the bike warms up, especially in Cold conditions.

If the bike is Warmed up and choke OFF, and the RPM's still rise.....this means you need to adjust your Idle, or you have an Air leak....usually in the carb boots or airbox.


Air leaks are more common though, make sure all boots are soft-ish and plyable.
If they seem okay, then proceed to attempt to tighten all 8 boots down a little more.
And check your airbox cover, make sure it's sealing tight.

Even the slightly air leak can cause the RPM's to "hang" or the idle to increase.

---------

And the reason you're getting screwed over, is simply because most people DON'T KNOW how to work on these classic Jap bikes.
It's really not that hard, you just need to read BassCliffs Tutorials, and get In and play around a little bit with the bike.

Yes, it takes some reading and trial and error....but it's worth it!

Number one source of air leaks is from the intake boot O-rings. I always replace these on each new/old GS bike I get.
