Harley released this morning two new Big Bore Kits. 107 to 128 Bolt on kit and 114 or 117 to 131 Bolt on Kit. New CNC cylinder heads, New Camshaft, New 128 timing cover label in complete kits or

SE8-517 Cam

4.310 Forged Pistons, Rings $374.95
Extreme Ported CNC Cylinder Head with larger Valves and CNC Chambers $1399.95

This is all the detail I have at this time but let the fun begin.

 

Meh. I'd still rather have the S&S or builders kits from here.

 

I don't see them on the website yet, but this certainly makes the Heavy Breather Extreme and Ventilator Extreme make more sense.

 

Understood, but there's also appeal to buying a new bike and having it built to 128 on day one with a full 2-year factory warranty and (presumably) EPA and CARB compliant for our brothers and sisters in California's regulatory scheme. Nice to have more options.

 

I'm with ya, but I like that they're mixing it up a bit.

 

Wow just did the stage 3 with 4.075 jugs n slugs in November. Wish I had known this was coming.
A big 4.310 bore with the shorter 4.375 stroke would have made for a deep breather that could handle some rpms for some serious horsepower. All under warranty woot.

 

they must have been following along with market research and noticed an aftermarket demand increase and want a bigger piece of pie..or Indian came out with a 127 and 130

 

Following for more details.... As noted they are not on the web yet... I know the new P&A rolled out at noon today.

 

The information I've seen shows them and NOT CARB Legal so those of us in CA cannot get them, they are however 49 state legal. My bet would be they are working on that part and will have it in the future. This information was sent to all dealerships this morning so I'm sure there will be more parts and pieces that are in the paperwork. I was told they also are offing a M8 131 complete engine too.

 

Wonder if the M8 complete 131 has a different crank. Any concerns going to 128/131 with stock cranks?
