Bike - '87 CBR600, 20k mi.

Hopefully you can see the intake shroud and 2 mutant phillips screws
(connected by a strip of sheet metal) per each of 4 carbs.

Such phillips screws won't break. Even with Liquid Wrench and a
mechanical impact driver.

Such phillips screws are soft metal, and efforts to remove them tend
to strip the phillips slots.

Such phillips screws shouldn't exist in this application. Bolts might
have been appropriate.

What can one do with such garbage?

Thx,
Puddin'

Perhaps they were installed using Loctite at the factory. Have you
tried heating the screws with a torch?

Don't set your bike on fire doing that...

Use the right tool for the job. First of all, get a screwdriver
that fits perfectly. Then apply hammer blows to the end of the
screwdriver while applying torque by hand. This is exactly what
I did just last week to get recalcitrant carburetor bowl screws
loose on a V-Star 1100. You can also use an impact driver but
the mass of the driver is not a good match to the mass of the carb
assembly. Just hitting the screwdriver smartly will break loose
the corrosion between the steel screw and the aluminum that the
screw goes into.

I just perused through your previous thread, not sure what you're
trying to access by removing the brass screw/bracket, but you probably
won't need to.
I'll post more in your other thread.

Brass, huh? Sorry if I'm impeding this conversation, but I'd like to
know what's underneath that casting!
