Surging?

[blowndodge]

The last 2 rides I've been on I've noticed that my Nomad seems to have a slight "surging" to it.

I don't notice it on the freeways or interstates but around town. Like 3rd gear at 40-45MPH. I'll hit my throttle lock and my speed moves around like it "might" be missing.

Mileage seems to have fallen off a little. with my TFI set at 2:45 and 5:30 1st and 2nd pot I've managed to sneek into the 40's for MPG's if I don't speed much.

Last 2 tankfuls and not speeding I've got 36MPG's. This happens to be the time I "think" I've noticed this slight surging.

Before I rack too many unused brain cells has anyone here had this malady and found a simple fix? Hoses are all fine, checked them all. Bike accelerates hard wide open. Can still hit 110 if I really tried but I don't. Wide open she runs free...

Wondering if it's something in the gas? Pulled my plugs and they look perfect. they are original plugs but no need to change them when they are this clean.

Thought about turning my #1 pot to 3:30 like I used to have it when I was running regular fuel but that seems like it would crush my mileage more... I'm confused.

Air cleaner is clean. Injectors cleaned. ::)
