My GS1100 Project

Taping off the design is time consuming. I want the scallops to be perfectly symmetrical.

I'm diggin' the scallops and I think because the bike has a lot of black, it will look good.

The subtle gold on the bike should balance well with the tank. Looking nice!

Here's a pic before I clear coated the tank. The scallops were a pita to tape off but I like the results.

I really love the way this is turning out. I had seen a photo of just the frame and engine fitted in another forum somewhere and was hoping to come across the full build at some point. Here it is! Looks really nice - I am particularly liking the paint scheme of the engine.

 

[growler]

What paint did you use on the engine?

 

[Scratcher09]

On the engine I used duplicolor engine paint (I believe the color was cast iron)--primer,color,and clear. I powder coated the covers silver vein.

Looking good - those accents and scallops on the tank are sweet!

Do you have a fork brace on there? Saw the front fender off....wasn't sure if that was still in progress. Can't wait to see what you do with the seat.

 

[Scratcher09]

I am planning to hack the front fender to just a mini fender. I have in the past deleted front fenders on other bikes without a brace. Is a brace needed? And would just a tiny mini fender take place of a brace?

 

[growler]

I'd have to toss that question out to the forum. It was my understanding that some type of brace has to be used.

After posting about the brace/fender issue in e suspension section, I realize it is safer to have the front fender because it does help stabilize the fork from flexing when cornering aggressively. The fender does have a brace on the under side which stiffens it. A brace is the ideal but at my age I'm not as aggressive a rider as I use to be. I will probably trim the fender down some.

Today I cut and polished my tank. Before I put it back on I will probably synch the carbs. I have been running it with just the bench synch and it runs fine but might as well synch it with the vac gauges while I have the tank off.

Looks fantastic!

I am focussing on the seat now. I am building a cafe style seat. I want to have the option of riding two up so I decided not to make a fiberglass bumpstop. Instead I will be shooting for that shape but the bumpstop is going to be upholstered to allow for a passenger. I made a steel frame for the seat pan. The pan will be fiberglass and the steel frame will give it strength.

I love where you are going with the seat. I've seen so many cafe, tracker, bratstyle bikes that look as if the owner just gave up when it came to making the seat. It's cool to see someone still want to have the 2-up option and actually taking care in the construction of the seat pan. Excited to see what you do with it.

 

[Scratcher09]

I made a mold out of cardboard. Then I taped over it and waxed the tape to make it easier for the fiberglass pan to lift off of the cardboard mild after it cures. The back seems taller only because I am going to apply the fiberglass with the mold sitting on a work table and I want the mold to sit level. The lip around the edge will be trimmed to follow the frame evenly.

 

[Scratcher09]

After curing, I pulled off the mold and trimmed the edges clean. It is my first time working with fiberglass and I think it came out well. It is very sturdy. The fiberglass itself is very stiff and the metal backbone I welded up will give it added strength. The backbone is sandwiched in between layers of fiberglass. I wanted this pan to be solid and have enough strength for the added weight of a passenger.

Here is a picture of the underside of the pan. Next step will be upholstery.

I attached the foam and shaped it. Good quality dense foam is more expensive than cheap light foam but the difference in comfort is worth it. I will start sewing up the marine grade vinyl tomorrow.
