I bought mgpauls's TORS. I just added a Hyde bellmouth and K&N high flow filter to my '07 865 America. I'm just looking to perk up throttle response and overall performance a bit - particularly in the low to mid range. I have a Thunderbird which is currently in the shop having the Big Bore kit installed, so there is no point in dumping a bunch of time or money in the BA chasing performance that I already have in the bird.

I'm no mechanic so I will have the dealer do the rejetting. The Hyde bellmouth comes with instructions that recommend 124 mains at a minimum without saying anything about exhaust changes, and the calculator shows 126 for TORS with K&N single and snorkel removed. It doesn't appear to have an option for the bellmouth, but I would guess it would require at least a couple of sizes bigger.

My dealer is pretty good, so they may be able to measure the A/F mix.

Anyone know what the stock jetting is on the '07 America 865?
