Most Recent Big Bore Kits Reviews

Athena Big Bore Kit Athena Big Bore Kit Ler2112 - Murphysboro, IL More power "I have recently installed the BBK and the stage 2 intake and exhaust cams. The power gain is amazing. My ‘08 DRZ 400sm had 33,000 miles on it. Instead of reringing it I dropped some coin and went with BBK and cams. I’m so happy I did. Installation was easy, I have almost 500 miles on the kit so far with no problems. I just recieved my fcr 39 and will be installing it tomorrow. This thing has really come alive with BBK and cams, can’t wait to see what the fcr does"

Athena Big Bore Stroker Kit Athena Big Bore Stroker Kit Dave - Indiana Good kit "Yamaha 112 stroker kit. Doesnt come with all gaskets, crank bearings and instructions suck. The jetting / carburetor recommendations are way off. Parts are good quality but if you are not good at tuning 2 strokes... have someone that does know how to tune do it. Athena needs to rename this kit to half kit because its not a full kit of everything you need."
