Having used a couple of tanks of fuel now, I am happy that all of the old fuel (probably 5 years old) is now gone.
I decided that it was time to investigate the poor running at low revs. After attaching the vacuum gauges I find that there is no way that the number two brass screw is going to adjust. It ended screwed all the way in. Removed the brass screws to clean and lube the seal with a little silicone grease with no luck.
Off with the throttle bodies. I can see that the butterfly valves are not all closed but the number two is a little open when all of the others are closed.
I suspect that a past owner has been messing with the sync using the grub screws. Is there a guide to check these out there somewhere?
The bike is a '91 16 valve K100RS.
