Hey everyone I just bought my 2013 VRSC and am lovin it. But I am looking into eventually upgrading the engine to the 1400cc does anyone know the best kits or stats for the 1400 kit.
I just got off the phone with my buddy who works at the PDC in the Endurance Lab. HD went as far as the 1250 kit and had zero luck with longevity as far as cylinder liners. Way too thin after that.
If you decide to go at it anyways, be very careful of the oil jets when boring.
There are plenty of 1402's running around. Just stay away from wiseco pistons, they have a high piston skirt failure rate. CP pistons seem to be the one everyone is using without a problem.
