Looking at an 81 GL1100

Exhaust and Jets

Post by jasncab »

Hi everyone.

Got my '81 running after changing the oil.
I know I needed to address the belts.

First. I always thought the "nest in the exhaust" was just an old mechanic's tale, but nope.
I found two things. 1. a hole in the exhaust and 2. seeds coming out of that hole...

Anyway. I am thinking of chopping the exhaust right where before it hits the cross pipe and running it straight back a few inches and then down.
So not mufflers. In AZ I can get away with it where I am at.

What about jetting the carbs then?

Any adjustments needed? Looking at the existing plugs, the engine was running rich. It hadn't run for a year, so it might be just condensation etc, but they were pretty wet and black.

I'll be pulling the tank to clean it out over the next few weeks, so I might as well go through the carbs at the same time. (I ran the gas through a container to the pump).

Any kits to recommend for the carbs?
Any specific kits for the fuel pump? The diaphragm looked cracked.

Randakk best kits and most expensive and it's only the rubber bits, float needles OEM only aftermarket give most people problems but that's up to you. right now $10 for 4 1100 kits on Ebay??? get what youi pay for???

Jets shouldm't need changing running straight pipes.

There art no fuel pump rebuild kits; not meant to be rebuilt but can be..need vitron 1/16" diaphragm, drill press and small tap..how to's over at the NGW site.

Same with water pumps can be rebuilt but not meant to be..you

buy the parts or a kit from a guy in Denmark..bearings, seal, mechanical seal.

drill the shaft install washer and small bolt..harder than it looks
