I don't think they make a big bird for the 12R,just the regular HMF like BA had. IF they are making a big bird now for the 12R, you gotta have a BIG motor to make use of its 2.5" id mid pipe. Like ATLEAST 1361 but prolly more like a 1420cc.

that's what I was thinking Alan.
Certainly would NOT want to use it on a 1199cc 12R. I'd bet money you'd lose power.
Then again, with a sign-in name like BOOST12R,.......I'm guessing you could probably use the extra size.

HMF
The dyno graphs i've seen from HMF were 175hp and holding to redline,the sheet said w/pipe only no tuning?

The person that sold me my HMF said it was pc3'd. I'd certainly be interested in a big bird type setup for the 12.

it was PC3'd. no timing. "The Judge" or John810 (I think) lay claim to being the bike that produced the chart. Nothing special in it, just a few small minuses and pluses at 100% throttle.

My HMF was way off from john810's map. I had my own made and it made 176 with degreed cams and timming pc3 K&N's... Lots of tourque also. Very happy with the pipe.
