BB,
What you mentioned about the exhaust had me re-read the specs for the kit again. I'm not disagreeing w/what you are saying, but the kit says upgraded exhaust isn’t needed. [smiley=nixweiss.gif]
Screamin' Eagle® Big Bore Stage I Kit for EFI Models - 1690cc
This Big Bore Kit lets you increase the displacement of your Twin Cam 96-equipped model from 96 cubic inches (1584cc) to 103 cubic inches (1690cc). Includes Big Bore cylinders, Big Bore flat top pistons, rings, clips, and a Stage I Air Cleaner Kit with one-piece backplate, integral breathers, all mounting hardware, and gaskets. A high performance clutch spring is included to provide the additional clutch capacity required by the extra power. Requires separate purchase of primary cover gasket. [highlight]This kit is street legal when used with stock mufflers.[/highlight] (Not all components shown.) All models require ECM calibration. (priced separately). E.O. pending for '07 models.[/i]
From everything we've known from past in doing upgrades like this you would think as you mention that it would require an upgrade in exhaust. Also just because the MoCo is saying that "the kit is street legal when used with stock mufflers" isn't necessarily the best combination for the bike. [smiley=confused5.gif]
In regards of them keeping the take-off parts only reason I can see them wanting to do that is to resell them, and/or bore the cylinders out and use them on the next upgrade. Since it sounds like this upgrade/promotion is done on brand new bikes there wouldn't be any concern on excessive mileage on the parts.
