California Friendship Sidecar: Where to buy windshield? & Roof Repair/Replace

Webbing "windows" are a common modification. Don't dismiss the value of some sort of covering for the windows that might go on over the webbing. With a sidecar your driving season is MUCH longer and it does get cold in Colorado. Also, keeping the inside of the sidecar dry is a good idea even if your dog is the onl passenger. Good luck and welcome to the sport.

About Bikescreen... Most of their screens are just fine. However, the ones made for the EML GT2 DOES NOT FIT WELL. I know, I just had one crack while it was being installed. That is a $400 mistake including freight. Just be careful and buy their plastics bit if you do buy from them. It's not expensive and it works much better than a standard twist bit.

I am near Havana & Alameda.

That is a good point about varying weather. I do plan on riding year round. Maybe a couple different tops are in order.

I was worried about drilling the screen as I know they can be delicate. I figured I would need to research a special plexiglass bit. I will ask them to send me a bit when I get the screen. Sorry to hear about your cracked screen.

I know the area you are in. I am about 10 miles west across town between Sheridan and Federal near Hwy 6.

Tops are more expensive and harder to store than wndows. Just make a set of waterproof windows that go over or inside the webbing windows.

Good luck.

Your lower mounts are the type that are known to fail. Your upper rear mount is a Motovation sidecars mount and is installed in a way that it is very likely to slip. Normally the mount is placed on the main frame down tube and is of a type much less likely to slip then the Motovation mounts. Also it is installed in a manor that the forces applied are not trying to rotate it around the frame of the bike. In other words in line with the strut. The lower front is an early California frame clamp that is known to fail. Latter ones have 1/4 inch bolts to keep the "U" part from coming off of the block. Also it is installed improperly in that it should not be on curved section of the frame. Where it is installed not only does the frame curve up but also in. While these mounts have been working in the long run I would not trust them. The ball collet mounts California has some fail before they ever got out of the parking lot and these failures may have contributed to them going bankrupt about 30 years ago. There are several issues with these ball collets, the collet with even a slight amount of where on it or the ball which is a soft material called leadalloy the collet will pull off of the ball. Your upper rear mount is installed correctly however it to is the type of frame clamp that is known to fail. The lower rear being mounted higher then the lower front makes it hard to set the alignment as when ever you change your lean out, your toe goes the wrong way. So if you are trying to fix a pull to the right, you would lean the bike to the left which toes it out causing more of a pull to the right.
Lots of ways you can fix all of this, we of course offer mounts $775. Our mounts do use frame clamps for the upper two mounts. The lower front mount clamps to the frame tube and picks up the engine mounting bolt. The lower rear replaces the center stand and ties to the side of the bike putting the mount aft of its current location and below the muffler so that it is closer to the same distance off of the ground as the lower front. You would also need to replace the bosses (the part with the collet) these run $65 each you have a 45 degree and a 70 degree at this time and you would need two hiem joints $40 each. You could also drill for cross bolts on your upper rear, relocate the upper front, and fabricate new lower mounts doing away with the ball collet set up. I have personally had every one of these type of mounts fail on me when running a GL1100 friendship 1 rig.

First post: "...sidecar deal I couldn't pass up."

Later on in the thread: "Everything is wrong. Your side car is more then likely going to collapse into the bike catastrophically without warning."

I guess this means I shouldn't dual sport the rig before correcting and reinforcing the mounts. Well this sidecar rig just became an interesting project. Gonna have to go back to the drawing board and do the sidecar theory and design research I have been putting off while focusing on getting the bike running proper.

Thanks for taking the time to point out areas of concern and the flaws in my rig Jay. I really appreciate it. The knowledge definitely helps me get up to speed on the project. When I have a plan together I will certainly contact DMC for parts and supplies as needed.

Can anyone can help me with the following:

Besides the written works of Hal Kendall what other sidecar theory and design books are recommended reading?

Does anyone know of a GL1100 Friendship I sidecar build thread or photo gallery on this forum or elsewhere that has pictures of a properly set up rig with all the mounting parts issues corrected and the mounts properly placed?

Thanks.

We have the book "Driving a sidecar outfit" $34.95 lots of good information there. I have attached installation instructions for the GL1100 as well as alignment instructions.

Thanks for posting the files. Found the book on DMC site. Looking forward to it.

Why do you like to replace the windshield with a full height windshield?
