I ported and hogged out the stock making old and cut the carb mounting flange off, as the PHBG is flange-less. I used a digital caliper to measure the intake diameter so it would all work together. The carb is coupled with a piece of rubber hose and clamps. No leaks, good angle, stock location and stock placement so the factory air box can be mounted without modifications. Im currently running a 110 main and 48 idle. I might drop the main back to a 108 or order a 107 as the 110 is sucking too much fuel. The butt dynomax can't feel the difference, but as I literally watch the fuel needle dropping at WOT, I think it's safe to say it's rich. My previous combo was an unmarked idle that came in the carb and a 108 main. The 108 seemed fine, but I worry about trashing my motor with a too lean main; especially with the open Vstack. The idle seemed too small as it would sputter/bog a little when exiting a turn then opening to WOT. The 48 idle took care of this issue for me, and I suspect the unmarked idle was a 45 anyway, so seems legit. Anyway just thought I'd share and it may be of help to you. I'm currently working on a FOD screen with integrated filter to keep the engine around for a while. I'll post pics once finished and tested.
