After reading several hundreds of forum pages, I'm finally taking the plunge. I got an old 83 GL1100 about a month ago, turns over, fires up with starting fluid, carbs are completely gummed up after sitting for at least 6 years out in the weather.
I'm going with the 32DFT Westgl has advocated; I don't want to spend too much time tweaking to get the old girl on the road. (Or at least running!)
This being a tight time of the year (3 kid's birthdays in row, school supplies & clothes, Christmas right around the corner), I'm trying the PVC intake to at least prove the function to myself.
I'm bumping up the 5-way center cross to 1-1/4", with 1-1/2"x1" reducing coupling to slip over the outsides of the fitting. A little sanding is necessary, I'm doing a little bit at a time and trying not to rush. I shooting for a rigid and strong assembly, while minimizing abrupt, sharp edges and restrictions like you might see by pushing bushing into the center cross. I'm hoping this will give me just a little bit of volume for the manifold.
The carb and adapter to single bbl from [email protected]
came in last night. I had order two CPVC flanges, to see which would match up to the flange the best.
Looks like the 1-1/2" matches almost perfectly. What I like is this will keep the assembly as compact as I can make, plus I won't have any close lengths of pipe used to connect the fittings together.
