Are any of you guys running the BBR 120 Big Bore Kit? If so, how do you like it. Did it give the bike much more power? How much work was it to install?

Thanks

Hey Old-Man,
Thought I'd throw in my 2 cents worth-
I purchased the BBR120 kit and installed it myself one evening in my garage with nothing more than some basic hand tools, feeler gauges and a torque wrench. It doesn't take any more knowledge than can be easily extracted from following the step-by-step assembly for a stock piston install listed in a Clymer manual. BBR lists a couple things to be aware of but I had a seamless assembly with the bike firing up on the third kick. And although I did make other mods to my CRF100/120 (BBR pipe, bigger carb) later, the 120 kit was the biggest gain in power hands down. Highly advise anyone wanting more power (equals fun) to get one of the BBR kits. Especially now that they've come down in price.
