I got 2 picco 26 when they first came out had small issue with the low speed needles. No problem there different low speed needle. Fix for the leaking front bearing was double sealed bearing. Other than that very strong engine ran great tons of torque to move my savage. I got 3 picco 26, 27 and 2 picco 28. The picco 27 same size as the picco 26 but with sleeve porting.
