I picked up the bike at noon and all the techies were gone to lunch. Owner was there and said he would write down the tune number when he brought my bike around. When he came back he said he couldn't figure out how to look it up, but would ask the techs when they got back.
I called back later to remind them to save my old foot pegs and the owner said he'd told them to write it on the box for me. I'll pick that stuff up tomorrow and let you know the number.
From talking to the owner though, it doesn't sound like anything new - he repeated what you said that there was a tune for ethanol up to 25%. Anyway, you'll be able to figure it out when I get the number.
On the bright side, I can absolutely tell that they did something to the bike. It is definitively quieter - compared to before it almost purrrrs!
I didn't realize how noisy it was, probably because I didn't have a frame of reference. Overall it just sounds "tighter" and runs smoother and you can hear the exhaust note better too. I also didn't experience any popping, and I drove for about 30 miles and purpusely decelerated hard trying to make it do it again. I'm guessing it never had the proper tune done since I picked it up new.
On a separate note, I really like the floor boards. At first it was a little awkward, but once I got the hang of using my heel to shift I really liked it. And the ride is much more comfortable too with my feet planted flat. It does seem that feet are positioned slightly farther back than before which I'm not sure will be better on long rides. I guess that means cruising pegs for my engine guard will be next!
If anybody out there with a newer bike is having starting problems, popping noises or just an abnormally noisy engine, I recommend you make sure you have the proper tune - Daz in right - it can make a big difference.
Life if good - at least for the moment!
