Could be a few things, when have the valve clearances been adjusted last?

not sure. no valve noise.
plug dont look to good. burning clean but still old.
good gas. clean filter.
when i first start it it starts right up .
but if the choke is not on it dies and will not start for a few mins.. when it did this i putt 1-4 plugs and they where not wet..

Don't wait until the valve make noise before adjusting them.

The valves on a GS will tighten up with use, making them quieter, not noisier.

Adjust the valves, make sure the carbs are clean and adjusted properly, it will start with minimal cranking and will purr like a kitten.

How old is the battery? Have you checked the charging? Battery not up to snuff can crank it ok, but have a hard time starting cold.. Check to see how much the battery voltage drops when starting. If you can turn the headlight off..
Could also check the petcock,if cyl 2 is flooded could slow the cranking speed

That's your first clue. Silent valves are too tight and cause hard cold starting.

Adjust them before you burn a valve.

Get an adjustment table from Steve

And instructions for 8V valve adjustment procedure are on BassCliff's site

... whats the best way to set the valves..

The BEST way to set the valves is to follow the procedure in your service manual.

If you don't have a service manual, you can download one at BassCliff's site.

BassCliff also has a nice tutorial that shows the procedure better than the factory manual.

Yes, I offer a spreadsheet that will help you figure out what shims you need. Details are in my sig.

I have a 16v 1166. Do i need shims?

[alke46]

Just looking at your sig. I see you have 4 GS's and don't know yet how to adjust the valves? Wow!!! You need to do some serious reading on Basscliffs site.

How do you expect to keep these machines running well if you don't do at least the valve checks?

Sorry if this sounds too harsh but really, to own these beauties, you need to be able to do the routine stuff yourself.

lol

dude thats easy.. i pay to have it done...
but they run so good i hardly ever have any trouble if a clean them keep up with the oil and gas , filter's and so one. i only ride one of them like hell.

i got lucky and had the screw all ready
