New to me ST1100! I find another community to belong to!

Update and thoughts:

I’ve been knee deep in carb land. I think I’m on the other side of this game now with them. Basically rebuilding the carbs to near-new condition with 99% new guts. Part of this endeavor got me purchasing an ultrasonic cleanser, that came in handy and they really cleaned up well! Weather is changing, so I think painting will be in the future soon.

When I rode the bike to the DMV i noticed the front brakes were crap. not so much squishy, as they simply had no bite. The rear brake did a better job of slowing the bike down. I imagine when I take the front wheel off to do tire and bearings, scrubbing the rotors with steel wool and a new set of pads will do it a lot of good. That and the new master cylinder and steel braided hoses…

One thing that I have not yet disclosed is how much I’m into 3D printing. I can print relettivly large items too, like half-meter in length, height, width. What has surprised me is how there is a distinct lack of 3D printed fairings and tidbits for motorcycles. I would have thought rapid prototyping and iteration would go hand in hand with motorcycles… I can print in ABS, ASA, Nylon and Carbon-Fiber reinforced mixes of those. Not trying to go race-mode here, but maybe I can find a way to give the bike a lightly “this-century” look… nothing crazy, but sharper lines would look good… lol

Someone 3D scanned one of our rearview mirrors, I bought a copy of the 3D file, and I’m going to see if I can mate a different rearview casing onto our stock fairings. Keeping the original mounts.. we will see… I might end up buying a 3D scanner myself just so I can get accutrate mounting points for plastics. Maybe I can do a full re-dress kit… Again… We’ll see.

  • METRIC hoses, everywhere.
  • Throttle cables
  • 3D scan of a ST1100 mirror case (I’m thinking about 3D printing a new set, but that I can use with a commonly available LED lights and lenses)

Need to buy:
  • Right engine guard
  • Air Filter Housing O-Rings (wow these are NOWHERE)
    • I’m going to go to home depot or somewhere and see if I can make my own from stuff they have. I wish I had reference dimensions
  • Clear front signal lenses
    • This might be something other than making my own clear ones, I’m thinking all-new parts
  • LED tail lights

Need to figure out:

  • How to make the bike not stink like a lawnmower when I ride it
    • This i am chalking up to the carbs being out of whack… i think it will get better
  • How to shift out of first to second without grinding gears (all other shifts are fine)
  • How I am going to paint the bike
    • Rattle-Cans for the Win!!!!! Bought a paint booth too. I’ve got four cans of 2K clear coat now.
  • What I'm going to do about the painted gusto-grey parts
    • Rust-o-lium Automotive trim and plastic paint. It adds a little more texture, it’s black and will give a nice satin look to the “trim” parts.
  • If I like the stock seat shape and color

Welcome to STOwners - from Harrow, ON Canada.

Great bikes and tons of knowledge here!

SUGGESTION: you might consider changing the timing belt. That one is likely pretty old and since it is a "rubber" component, I view them as sort of like tires: they have a best-before date. If it breaks or loses a tooth, you could scrap the engine.
 
One thing I didn't see folks talking about is the fuel shut off. This can cause an issue out on the road. It can put a crimp to a nice day. It is not a hard thing to overcome, but a issue on the side of the road. Folks, feel free to chip in with the fixes.

Covered in post # 48 by the Maintenance Items Needed for a New (old) Bike check-list document that was suggested for his reading pleasure.

The temporary fix is to simply bypass the fuel cut-off valve. The permanent fix is to either repair/replace it or leave it bypassed permanently. Dealer's choice- Depends on your preference.
It is pretty simple to bypass it. Below is a link to an article on how to do this. It was written by Michael who had to do it as an emergency road-side repair while on a trip.
