I know there are a lot of 1100s out there with trashed carbs, the bike isn't worth enuff to justify a carb rebuild, or to buy an expensive Kit, and still not be sure what you will have when you get done......Well after building a single manifold a month ago out of sch 40 PVC and loving the reliability and result, I decided to put my Hardware skills to use and come up with a cheap, easy, alternative build for the Mechanically Challenged. Now if your gonna get into a discussion of air flow, torque, and BLAH-BLAH-BLAH. I don't have a clue. This is a cheap and easy way to make a GL1100 run, and mine runs GREAT.
All fittings are 1" schedule 40, and available at your Local Hardware Store (like I owned for 35 year), or Lowe's for about $12. The only modification to the fittings are the 4 45degree ells, they must be trimmed a little where they attach to the 3 way tees in order to get the correct width to match the 4 stock rubber manifolds(the sch 40 1" fitting will fit perfect inside the rubber manifolds). The Polaris rubber carb mount is available on e-bay for 10 to 20 dollars, depending on which carb you choose you probably will have to make the mounting holes a little wider.. I used a VW pict 34-3 carb, new they are around $ 100, used they run the gamut......But the carb choices are endless.......My bike runs great, no Hydro-lock, no syncin, no ethanol problems,,,,,,,, I like it a Lot.......
List: All 1" sch 40 fittings....2 ea 90 degree St Ells...2 ea 3 way Tees (or side outlet Tee)...4 ea 45 degree Ells, I ea Reg Tee...1 ft sch 40 PVC Pipe....4 new screw clamps for rubber manifold (old clamps will not close tight enough)--or you can use 4 ea 1 x 1 1/4 slip bushings in the rubber boots they fit perfect but you need to ream out pipe stop at end of bushing, then you would use your original clamps...1 ea Polaris rubber carb mount...Ur choice carb.
