    Good point! I did my own and posted it in one of my threads.

    Lots of interactions going on in this thread. Do's and Don'ts are always fun to read.

    Yeah. Is there another way to know?

    FYI I'm at a half turn on my fuel screws right now and it's still driving the same, although it's idling slightly lower.

    Remove the valve cover and check it yourself now - will only take a few minutes to check and a few days to get shims and a gasket if you need to adjust any of them

    Have you considered the PO may have adjusted the valves badly? The only way to know is to check them yourself. Do it and eliminate the valves are the problem. If not, everything else you do to fix your MPG issue will be in doubt..

    Process of elimination...good idea!

    No disrespect to Mr. jimhickcox but threads like this typically follow the following theme: the brethren here at GSR offer possible ideas for the root cause of the issue and the OP (original poster) shoots them all down. Simple matter of act is that a bone stock 1st gen GS750 should be able to fairly easily average 40+mpg if everything is up to snuff on the machine. If the bike is not able to match this it's time to dig into routine maintenance first and troubleshooting secondly. Compression, spark, fuel. Go back to basics until the problem is solved.

    Totally agree with nessism on the PM (Preventative Maintenance).

    As for the dialogue, well that happens. Lots of personalities on here so smart-alecs abound...lol.
