I don't know man, I'd check to see if you're twisting the throttle all the way. The bike, even on stock gearing is stupid fast in 1st and will blow through 100 mph in a matter of seconds. I weigh 205, and if I get on it hard of the line, the front end will be coming up around 8-9k, and if I don't ease a bit I would be on my ass so fast it wouldn't be funny. I am -1 front and flashed. One thing I have noticed- a lot of the guys riding these bikes chill around 3k rpms, shifting around this as well. I ride around anywhere between 7-8k. Keeps it more in the band so when you want to go, it will go now. These biles are supposed to be run at high rpms- they like it there. They are completely different than Harleys.
