1980 GL110i - Gamera

Post by 507Derek »

This is my 1980 Honda Goldwing Insterstate the day I bought it.
20190516_173926.jpg
I bought it with the intention of stripping it down and riding the snot out of it. I wanted an older bike with bags and always liked the flat 4 of the Goldwing. I did a bunch of research and found a few guys that had built something similar to what I had in mind. Found this one for about $1000. It had quite a few issues when I looked at it. The previous owner did a single carb swap on it but didn't install it right so it ran kind of funky. The rear brake was seized. Exhaust leaked. It had a lot of wiring issues (i'll cover those later). But, looking for a project, I didn't really care. Bought it, took it home and got to work.

Stripped off a lot of the extra stuff I didn't want, replaced the big king/queen seat with an aftermarket one I had from a Road King and did some maintenance. Adjusted the valves, fixed the rear brake, LOF change, flushed all fluids, and trimmed the windshield.

It still wasn't running the best so I replaced the fuel filter, cleaned the gas cap, and found the PO connected the choke cable to the single carb which was making it do some funky things. Removed that and it ran much better! I removed the brake light and turned the turn signals into my running/brake lights, new front tire, and painted the windshield....

This is how I rode it for the rest of the year. It was a lot of fun and I got some compliments on it when I stopped to get gas.
Snapchat-1043079403.jpg
This spring I got to work on it's next stage. My goal was to create a bike that would be comfortable, quick, good in the twisties, and have bags so I could take it on some long trips. I love camping and would like to ride this all over, camping across the country.
InkedSnapchat-857717315_LI.jpg
Got it all stripped down to this point and ordered parts.

I had gone back and forth on getting rid of the fairing or not, and I'm glad I did. It was a lot of extra weight that I didn't need on the front of the bike, including a 3 pound counter weight?! All the electronics were removed so I could rework the harness. The fuel tank was removed. I cut off part of the upper "backbone" and welded in a single back bone so I could mount a traditional style tank.
Snapchat-145274243.jpg
I rebuilt and lowered the front forks using progressive springs. I got rid of the air suspension up front by getting some fork caps made for a Sportster. I replaced the rear air shocks with 11 inch Progressive 412's. I installed a J&P front headlight, TC Bros tracker handlebars, new throttle and grips. I bought a gas tank from a 1980 Suzuki gs1000 that was very close to the same size as the faux tank. I've always wanted to have a sticker "paint" job so I did that on the bag lids. Set it on the ground and pushed it outside to see if my vision was coming together.
Snapchat-2133481441.jpg
It looked even better than I thought it could.

Next up was to do the exhaust. The old mufflers were so rusty that they fell off as soon as I unbolted them. Got a couple pipes bent up at an exhaust shop and welded them on. And I removed the center stand.

All that is left is to finish up the wiring! Stay tuned....

:popcornx2 :popcornx2 :popcornx2 Fun stuff. So you are eliminating the air box? How will you handle the air flow to the carbs?

Good work Derek, How is you seat attached, did you have to modify much. I am interested in doing a solo Harley as as well.
Any pic's.

WIRING!!!

#11

Post by 507Derek »

Onto the wiring. This was by far the most difficult and time consuming part of the entire build. I have quite a bit of background in automotive electronics so it wasn't too terrible. My goals with the wiring was to get rid of any extra wires I wouldn't need for things I removed; dash, dummy lights, handlebar switches, etc. I wanted an automotive style turn key ignition. And, I wanted to move multiple parts to make it look better.

This is what I had to start with....
start.jpg
All of the electronics were removed, including the harness. I removed all of the harness wrap and found a lot of "fixes" the previous owner attempted. And some he didn't.

He replaced the main fuse with a piece of wire..
screw6.jpg
The single carb conversion was wired with home electrical wire...
screw4.jpg
The stator connectors were fried and he attempted to fix this bad ground wire...
screw3.jpg
He attached the spark plug wires with electrical tape, and the harness wires for the coil were barely on there...

WIRING 2

#12

Post by 507Derek »

I went through the harness wire by wire. Scratching my head trying to figure out what was needed and what wasn't. What needed to be jumped and what could be removed. I drew the harness out a few different times until I thought I had it right. I was moving the locations of some of the components so I mounted everything to the bike and ran the harness where I wanted it. Then I went through and shortened or lengthened the wires that needed to be changed.
Snapchat-1009984024.jpg
New location of the coil, spark units, regulator/rectifier, and ignition. I replaced both connectors for the stator because of how bad they looked.
Snapchat-964719107.jpg
New location of battery, starter coil, and new fuse block. I replaced the main fuse with a 30A maxi fuse and holder. And I replaced the old tube style fuses with mini fuses.

Here is a pic of the speedo and headlight I'm using.
Snapchat-126953257.jpg
This was right before I went through and shortened, lengthened, or added any wires.

Wiring 3

#13

Post by 507Derek »

I made sure the bike started and everything worked before I took the harness off again and wrapped it. Here it is, all done! Finally.
Snapchat-890695460.jpg
I have one fuse for the headlight, one for the taillight, and one for the speedo/carb. Plus the main fuse. The speedo uses a hall effect type sensor that I mounted on the rear wheel. Still need to calibrate and test it, the weather in Iowa hasn't been very good.

Here is the pile of leftover wiring.... I cut out quite a bit of stuff!
Snapchat-403321933.jpg
Here is the pile of parts that was either removed or replaced! I might have to weight it all before I get rid of it. I'm definitely curious how much weight I took off this thing.
Snapchat-1810915325.jpg
Still waiting to give it a good test ride. I've ridden it around the block but that's it. I'll post some better pics of it once I get it out on the road... :-D

It didn't have an airbox when I got it. The PO did a single carb conversion with a really crappy homemade jobby for an air filter. I replaced that quickly with a nice one that I was able to screw right onto the top of the carb.

Here it is when I started it to see if everything worked before finishing up the harness. Idle was high but it's a taste. I'll get a better one once I start riding. Probably going to put baffles in at some point. She angry....
