Base plate screw removal.

My carbs have been puffing out gas vapour every time I park the thing after a hot ride, so I took the time to start pulling it apart and replacing all of the various cracked rubber tubes, though now that I've gotten to the baseplate itself those delicate little brass screws don't want to budge.

I don't have an impact driver or really much in the way of power tools (other than a dremel), so I was wondering if anyone had come up with a good way of doing this?.. I feel like penetrating oil and a prayer isn't going to work considering the nature of the screws.

Pic attached if my description isn't clear enough. Bike is a 1992.

 

plain and simple: u need an impact driver to remove those screws.

someone sent me carbs to repair with these screws.......

 

Damn, alright.. Guess I'll ask around and see if I can borrow one.

 

BTW, i have a cleaned and rebuilt set of carbs for your bike for sale for just $385.

 

I use mine on more than just base plates. Buy one. Any person that works on older bikes (any bikes) should have one. There are some screws I don't even attempt without it. I just know it will immediately round out.

And we are talking about a mechanical impact driver, not power.

 

if someone just really HAD to remove those screws crudely, on a third-world itchyboots ride, a chizel and hammer could be useful to turn the screws, then order new screws or replace with socket-head cap screws, etc. dremel can help too.

 

JIS screws?

 

might be hard to find a JIS impact bit and probably not necessary in this case.

 

You must be referring to the little bastard screw caps that cover the brake pad retaining pins. Those get a sharp clout with my impact driver before I even think about a regular screwdriver.

 

Have seen those "Pad Pin Plugs" totally buggered up, I use antiseeze and gently use a screwdriver to torque them. A small little vice grip (pressure pliers) could be your friend too, and the obligitory impact driver. It is nice to break out a hammer and chisel every once and a while, just did the fuel pump on my Jeep 4.0 and was waiting to blow up in my driveway, mission was successful because that was last week and I am still here. Peace

 

Later years they were replaced with rubber caps. I bought rubber caps for all of my bikes that had them and replace them as I have to get in there. They were always a dumb idea...

 

A little late for this ! Those screws are ALWAYS JIS (Japaneese Industrial Standard) Standard US Phillips are slightly narrower and longer. This causes the phillips to bottom out before they fully engage and that causes the screw heads to strip. Look online and see if you can find JIS screwdrivers or JIS 1/4" insert bits. My JIS screwdrivers are made by Vessel in Japan. You can find them on Amazon. I dont need an impact driver anymore! Always fit your screwdriver or bits lightly by hand to make sure they are snug, if they wriggle, Don't use them! In a pinch you can take a standard Phillips and grind or file the tip about a 1/16th. or 1/8th. of an inch. This will give you better engagement but it wont be as good as JIS.
