Here's the update. I ran with my buddy that has the M109, rolling start in 1st gear, like 5mph. Couple horn beeps, and go. He was totally confident that I didn't have a chance....kept saying there was "no way" a 1200 could take an 1800, despite knowing that my Max puts out more HP, more torque, and weighs a good 200lbs less.
If I whacked the gas in 1st, the rear tire just instantly lit up and the ass started fishtailing like crazy, so I couldn't actually go WOT at the "third beep". His 260 rear tire took me there and he got a quick lead....my POS avon tire just couldn't hook up. However, by top of 2nd gear I was right back next to him, and when I hit third I walked away. I didn't go WOT until I hit third gear...with this rear tire going WOT in first or second just means instant burnout. The other interesting thing is that right as I had hit third, he was already in fourth at roughly the same speed. Right as I was really starting to haul in 3rd, he was fading having to go to 4th.
From a rolling start at 55(I was in third, I dunno about him), it was no contest, I handily pulled away, probably because I could actually use WOT without fishtailing like crazy.
Sooooo....I need a new tire. If I could hook up in even second gear(first would be great, but I'm not sure any tire is up to that job), I would have dusted him that much quicker. The 109 is no slouch for performance, but it's still a heavy v-twin cruiser
