1981 GSX1100 Katana Based Project

...make bar weights from round polymer, should weigh about the same as cotton candy?

Are you proficient with anti-matter?

[Shin-Ken 1074]

Yep, Anti-Matter and Dark Matter. Very difficult to find a supplier post COVID, Anti-Matter tube to make a frame would be top of the list.

As our current weight loss champion,

Maybe the Kat could sign up as a "Weight Watchers" success story?

Always a good day when parts arrive.

My Kat Foreman wants to see a table of weight savings by descending order in order to guide future weight watchers in their quest to fly to the moon.

With the new throttle cables and a GSX-R1100 switchblock to match the twin cable throttle tube 2/3 of the job is done. The remaining 1/3 of the work is adapting the GSX-R 1100 switchblock wiring and harness connector as the harness connector blocks are different between the GSX-R and the stock SZ Kat. After swapping to a stock SZ Kat harness connector block and sorting out the wiring it should be good to go. That is a job for my mate the Electric Wizard.

I second that emotion.

No problem, all the details have been listed here. Just follow the bouncing ball through the posts and you will be able to compile a list of parts and weights in your preferred order.

New seals and pistons today.

Cleaned the pistons with acetone to remove any contamination from the manufacturing and packaging process before installing the pistons.

Wipe pistons dry and then let them sit for awhile to ensure all the acetone has evaporated before installing.

Installing new seals.

All four new seals installed.

A very light film of brake fluid on the seals and pistons help the new pistons glide past the new seals with finger pressure.

Used Red Rubber Grease for the slide pins and boots.

Used a pine rod to install the captive slide pin boot, makes it easy to install.

second that, i am in awe of the weight loss achieved (and the detailed documentation), and think anyone trying to achieve similar would be very happy to read through this thread. Added to my favorites early on.

Hi Rijko, glad to hear you think it has been a worthwhile project, thank you for your support.

Cheers.

Wanted to install the carbs and new cables today however, today was just too hot and humid to do anything. 40 Celsius and 95 % humidity is not my idea of fun these days so the carbs will have to wait. Aircon and cold beers were a much better option today.
