Hey Cen guy, I sripped 15 pairs of GEARS on my tr-4. I had so many problems with my belts. pebbles in my belts. Seized engine twice. The Genesis looks cool but im not going to spend another penny on CEN. i got a savage. it was a good choice. I was a newbie back then, i figured ot later that my shaft was bent. So i replaced it and ran it. Stripped another pair of gears. It's not my gear mesh. i know how to set gear mesh. Now my Cen is retired.
