Has anybody with a 2011 SG 103, installed the SE Stage II Big Bore 103 Upgrade? I would like to know thier thoughts on this kit. Or does anybody else have any info on this kit? Is this kit worth it?

 

If I were you with a stock 103" I'd either go with a 106" big bore & a compression bump or just do the later. Throw in a set of cams and mill the heads - compression & air flow = power!! Don't get caught up in cubic inches - it's what you do with them that counts.......

 

The stage II kit has the same cast flat top pistons you already have. All you need is the stage I air cleaner and the SE255 cams. All you'd need then is a tune, and you'd be good to go. Lots of guys running the stage II kit and are very happy.

 

If you already own a 96" Stage 1 with a SERT, is this kit worth it? I'm thinking of putting one of these on this winter.
