Used a brass hose barb to connect the other outlet hose from the fuel pump to the return line that came off the base of the stock Mikuni, so that should close the loop as far as the fuel feed/return lines go.
There were two hoses on the stock air cleaner, one for the valve cover breather and the other to that gizmo on the exhaust side. I removed the valve cover breather hose and just put one of those small APC pleated filters on top of the valve cover fitting, and just left the other hose as is. Would it be worth doing anything fancy with this other hose, like trying to route to the inner fender air inlet for the stock airbox, or just leave it there on top of the valve cover?
There is one odd thing going on. When I first start the Monty in the morning, or after it's been sitting for a few minutes, it makes this rattling noise, and it's running a little rough. After a few minutes, it's like a switch gets turned on, and the idle smooths out and it runs fine. Is this the electric choke working?
My initial impressions are very positive. 'Course this is comparing a fully functioning two-barrel to my Mikuni with faulty secondaries, so it's not a fair comparison. But it's nice to get my daily driver back! The Weber is so simple compared to the Mikuni, but I supposed that's why the Weber isn't street legal in CA, because it doesn't have all those freaking vacuum hoses going to God knows what.
I'd say the Weber kit was worth the $295 I spent on it, since trying to find a rebuilt Mikuni or getting one rebuilt is FAR from easy. 'Course I probably could've picked up the intake side of the SQ turbo system for less money than I spent on the Weber, but knowing my luck, I would've FUBAR'd the EFI install. At least this way I have my daily driver back, runs great, hopefully will get a little better mpg, and I can keep the SHO for sunny days.
