Many
Vmaxers have removed the pilot mixture screw plugs from their carburetors
in order to be able to make adjustments to improve the drivability and
performance of their favorite motorcycle. Doing so usually leaves a gaping
1/4 inch hole that is not very attractive. In addition to being somewhat
unsightly, leaving these holes open invite corrosion which unchecked may
lead to the fusing of these very delicate screws and endanger the
serviceability of the entire carburetor.
1/4 inch
polypropylene plugs are available at practically any hardware store. They
are easily installed and just as easily removed for subsequent service
adjustments. Even if you decide to not cover these holes, be sure to
protect the pilot mixture screw threads with a light coating of silicone
grease or a suitable "never-seize" compound.

OK ... Lets Cover
Some More Holes
There seems to be no
logic why some of the exposed socket screws on the Vmax are filled
with a nice chrome button plug while others are not. Depending on
personal preference, there are more than a few opportunities to
dress up some of these fasteners with original factory buttons,
(Yamaha part no: 90338-08163-00). |

OK, you are probably
wondering where those chrome shock donuts came from. The donut is
actually referred to as a "washer" and is available as Yamaha part
no: 57A-22243-01-00, from late model Viragos. In order to accept one
of the factory button plugs the top shock bolt must be changed to an
8x20mm socket head, (available from just about anywhere or from
Yamaha as part no: 91314-08020-00). The seat rail and the lower
clamps accept the plugs with no modification; just "plug 'em in".
