NK100.31.2 - Naraku 70cc Cylinder Kit V.2 For Benelli 491 50 AC 2001-2003

Features: High-torque 70cc NARAKU cylinder kit. This cylinder kit is not designed to be revvy, but rather it shows its strengths in the lower range. Just above the idling speed comes solid, constant and very strong acceleration. All that, without straining the engine at unnecessarily high engine speeds. The power output from standing make for very good starting and traffic light getaways, and "hill climbing" is made easier, even with pillion! The sound is fairly standard. This cylinder highly suitable for everyday use, because the performance improvement can be achieved using the original exhaust system. Compatible for original and sports exhaust systems. Jetting must be increased [+7% to 10%]. We recommend using a head with a chamber suitable for a 70cc cylinder, such as the Naraku 70cc head. The cylinder can however run using the standard head. This creates higher compression and the electric starter could have issues turning the engine.
