the thing you have to remember is this bike even with the bbr 120cc kit is still a small bore air-cooled motor. so, expectations need to be consistent with this in mind. having said that not only does this kit add 20cc (20% more displacement) it also comes with a high performance cam. so, this is a kit that will definitely make you take notice. the increased power is definitely noticable. we are in the process of adding additional modifications such as exhaust, jetting, air filter, rev box, etc. we're anticipating even more power gains from this combination. i think the cam and 120cc big bore kit could use more air/fuel and exhaust flow to maximize it's affect. even still without these additional mods the bike with just the 120cc kit is significant.
