Blame my friend Joedrum for this post, he asked if I could post some information about the single carb set up on my 1100 Interstate.
The first thing I will say is that I am completely happy with it. I bought her without knowing there was any conversion (at the time I knew nothing about Goldwings) I am grateful to this forum for changing that.
I have about 4,000 miles on it now and she has always started easy cold or warm. She idles very smooth and I can drop it down to about 700 RPM before it starts to have a problem, I normally run the idle around 1000/1100 RPM. It accelerates very well and the second barrel opens up around 3/4 throttle. I never turn the gas valve off and haven’t had any problems with fuel bypassing the float valve. The only problem I‘ve had was the accelerator pump developed a leak and I couldn’t find the correct replacement. I bought one that was close and filed the push button down about 1/32" to make it work.
I average around 35 mpg and close to 40 on the highway.
I haven’t been able to find exactly which Weber carburetor it is. The numbers I found on the base are 28/300 which makes no sense to me or the auto suppliers.
The idle problem I've read about seems to be on the tubular (non-heated manifolds) they complain about a cold intake and condensation build up on the outside. This one is heated by the coolant and has a petcock on each side to burp the air from the system.
The only thing I would change would be to reinstall the return throttle cable, right now it only has the pull cable and a return spring. If the spring should break or come lose, the kill switch would be the only option.
I told Joe I wasn't sure I knew enough about this set up to make an intelligent post but his answer was that intelligence wasn't a requirement on this forum. :smilie_happy:
