I installed the Booster Plug on my 09 F650 Twin. Pretty easy. I'n my opinion, it's made a big difference. This is my first FI bike, and I wasn't digging the throttle response. I tried to get used to it, but after almost 4k kms, it was still an issue.
The change was instant with the BP. It really slowed down the way it rolls on. Almost stalled the bike at first. It also feels better coming out of a slow corner. Hitting the throttle half-way and the bike just chugs out really nice and strong. rear tire even broke loose, but there was no panic, just nice and even pulling through.
It also sounds just a tiny 'thicker' on the low rpms, but that could also be my imagination.
Anyway, happy with it.
