[QUOTE="chuck c, post: 134882, member: 2907"] That's what I had in mind. I'll do the pipes in the cross then work out. 2 and 3 first (the ones with the cut down connections) then 1 and 4 worked well. I actually got 1-1/8" of pipe in the cut-down connections so they are very strong with 9/16" in each side. I think 1-1/4" pipe and fittings would still work, they would have to be cut down a little more but there's still probably enough socket to make a good connection. I've got the pipes cut so they are a pretty tight fit when in the right length but when the glue is on they will go a bit deeper. I'll scuff the OD of the pipes and ID of the connectors with sandpaper and clean all connections with solvent too. The Mikuni flanges lined up on the head ports perfectly when they were pushed to one side of the bolt holes. I just had to put the screws in loose, push one way into they were touching the screws, and bingo. Got to watch tightening the screws. There's a recess around the holes on the mating side (visible in pics) to be sure of good contact everywhere else. It's easy to lift one side of the flange when bringing down the opposite screw. I had to light finger tight them first and tighten them evenly to be sure they made full contact. No gaskets- nice! [/QUOTE]
