Do you drive down the highway with overdrive off in your personal car? Or in manual 2nd around town? At really light throttle there isn't much reason to wind the engine out, unless you just like the sound. There isn't anything wrong with that- just realize your fuel economy is suffering. If the bike ran like crap shifting early it wouldn't be published in the manual, for starters. It's bucking because you're giving it too much throttle at low rpm. Back off the wrist a tad and it'll run smoothly.
Mine doesn't buck at all, I'm routinely in 6th in city traffic, going 35 mph. 1000 rpm is a stretch, but it can handle 1500 with no issues at all. You're riding something with 1300cc's of displacement, it can pull a tall gear without difficulty. It's not a Rebel 250! It also doesn't get rebel 250 milage, either.
First = I do not own a CAR, but have had many in the past and my wife has a truck that has an overdrive button. It is only used in the mountains to increase RPM's when climbing. The cars I have owned have been Porkchops Alfa's and Lotus's And AGAIN I must say this: THERE IS NO WAY, NO HOW, THAT A CAR OR BIKE SHOULD BE DRIVING OR RIDING IN IDLE MODE!!!!!!
I AM JUST STUNNED THAT ANYONE WOULD EVEN BEGIN TO TELL ME THIS IS THE WAY AN ENGINE WAS DESIGNED!!!!!!!!!!!!!!!!!!
I am ranting Because I can not believe you actually ride a Bike, much less a Busa, in this manner!
I am really risking My rep here on the Org, as I am bout to come unglued.
I may just have to try your method one more time and shoot a video of me!!!
Don't queer on me pitch, cause you ain't herd me out yet!
