Default 1200 to a 1340

I hope this isn't a stupid qustion. Can a EVO 1200 be bored to a 1340, or is there a kit for bigger jugs.

Yes, you can go bigger than a 1200 on a sportster. Check out NRHS Performance, I've heard nothing but good things about them.

Yep, but anything bigger than a 1250 kit, you'll need to bore out the cases to accomodate the larger cylinders. Check out xlforums.net There's a number of guys over there that have done larger kits over there.

Just put in the 1250 kit this year - runs great. You can do it in the garage if your comfortable tearing the bike down. If you do, don't forget a tuner like the TTS or go have it dyno'd. I'm sure it was a bigger jump for me than from a stock 1200 would have been though. But, they also have head kits if you're really looking to make her scream.

88" can run 5 to 7 thousand said and done.
Some builds are sweet as hell and some are loaded with drama.

Damn! I can just about pay off my Sporty with 7K. I just think I'll wait and get a Fat Boy Lo or a Fat Bob when I get my Sporty paid for.
