My 1100 did the same so I fitted a E-Prom Chip (£25) from germany and splitfile spark plugs...Runs like a dream!

The 95 1100 had bigger valves than the later models and was prone to surging.

I think you will find it's throttle sync more than anything. If it's been done by the dealer then it's bound to be miles out.
Your bike will have a cross over throttle cable thats a bit naff and lets the carbs go out of sync easily when the cable wears. Fitting the later throttle cable setup helps.

I rode a 95 1100 for years - quickest ones of the lot

I agree with Rob, TB adjust but I'd do the valve adjust too.....

Surging seems to be more to do with not taking enough time to match the valve clearances than anything else.

checked the valves but was confused about the, i dont know how to describe em but here goes. they sit on the end of the valve stem like a hat but with the valve going throo them , was difficult to get feeler guages in .
i cudnt find a picture of them in the haynes manual, are they different on the 95 model , or is there an aftermarket part ye fit to possibly stop tappit rattle?
any ideas?

hi big lad , it seem like its on the throttle up in third the lunge happens it has a metalic feel to the action not like a fuel surge , so it could be gear box , bugga.
thanks for the info.
