Oh yeah, head work time

Hot damn, sounds like you got the works! I'm sure some of that noise will quiet down once it settles in and it gets out of the garage I'm a bit new to headwork specs but aren't 1.94 intake valves a bit big for the stock throttle body? Are you planning on an upgrade soon or will you be keeping the stock on? Cheers to your build!

In fact, with a bit of basic math, given that the 46mm TB can flow 245cfm and has an area of 1662mm2, the 50mm TB should have an area of 1963mm - or 18% more than stock. This should equate to a max flow of 289 cfm. All rough theoretical numbers of course.
So it looks like an ideal match to Robby's (and my) heads.
Robby - where did you find these at $319 - I might spring for one!

Sorry to get everyone's hopes up, feel like a real dufus. Ended up doing a fun color run with the family (my nose is still full of colored chalk lol), and temps here were 75 so I opted to run then ride! This weekend is looking like a winner, wife is pissed seeing manual and tools everywhere....

On a positive note, I got mine all finished up last weekend and even got the bike out for a hour or so. It seems to pull like a train - especially from around 2500 rpm or so. No idea where it tops out yet, but it certainly got up to 90 in no time at all and I didn't want to go further as the roads were wet and slippy.
I did a half hour auto tuning run with the Power Vision, then refreshed the map, but haven't ridden it yet since then as I am out of the country on a trip.
I'll probably do a separate thread in the near future to show the process and results...

So do you just stick with your base PV map and then auto tune even though you've had head work done or did you make some changes based on the work done?

The bike ran great even before the autotune session - so no issues there.
