Hi all.
I been trying to put bar end weights on my scrambler, the bar end mirrors i had, the metal part that goes inside the handlebars would not come out, so i decided to ram it further down the handlebars. :|
Anyway, this made the screws on the brake fluid reservoir come loose, so i tightened them and BAM the head and about a few mm of the screw broke off.
Now i'm screwed. I have no idea how to get the broke screw out of i can then i have to find a replacement scew?! help, im a bike

I think the original cap heads are 20mm long, but both sides will take a 25mm long screw.

If the screw has broken inside the reservoir housing you have a delicate surgery task in front of you, easy-out, or maybe even very small drill then easy-out.

Hopefully there is a wee bit of the screw protruding from the reservoir housing and you can grab it with a set of multi-grips.

I don't think i have enough to pull the screw out, but i think for now its ok, i mean it should be on tight enough where the fluid won't leak out. I'm not driving my car to work today.

Never mind, it is definitely leaking fluid more from the side with the broken screw. i might cry.

Oh, it is the cover screws, I misunderstood and thought it was the reservoir to handlebar screws that broke.

Those little screws for the cover are smaller, about 4 mm x 10 mm I think, but can't find a specification on them so the other one as a sample might be the way to go.

Try a left hand drill bit slightly smaller than the shaft of the screw. Go slow with moderate pressure. If it drills through without loosening the screw, use any easy out in the tiny hole. If all else fails, you can drill and tap the hole for a slightly larger screw, but it won't look pretty.

I could always end up replacing the entire reservoir but problem is i can't find OEM parts online.
Google search not helping.
I really don't want to ride all the way down to dealership i don't know if they would even help me.

Google Star Twin Ducati for an online parts fiche. Be sure to clean up any spilled brake fluid, you don't want that near paint.

At 70 YO and riding since age 22 this is exactly why I've given up mods to or NEAR critical parts. Murphy's Law commonly wins and when it does it can be expensive :-( On the plus side, stuff like this can always be fixed by someone with the right tools and right replacement parts. It can get expensive though.

Find an independent mechanic who is confident about removing broken screws. It's a learned skill. He doesn't need to be a bike mechanic. I know I could get it out.
