I chose to use the Clymer manual to do my first oil change.
was a mistake because, the
picture on page 52 "(A, Figure 21)" points to the wrong bolt head!
In the Clymer manual, the oil change instructions begin on page 52
about half way down the
right column. The itemized instructions begin on page 53 at the top of
the left column. We get to item 3, the second sentence says...
the oil drain bolt (A, Figure 21)" and we look at Figure 21 on page 52
and are directed to a bolt head clearly only a couple inches from the
oil filter. THIS IS THE
WRONG BOLT! THIS BOLT IS NOT THE OIL DRAIN! We have now
looked under the engine and have identified the "oil drain
shown in "(A, Figure 21)" so we don't notice the discrepancy in the
of the sentence "...from the left side of the crankcase." The bolt
pointed to in the picture is NOT on the LEFT side of the engine. We
bolt shown in picture "(A, Figure 21)" with a
and get maybe a pint of oil. We wait the step 4 "at least 15-20
minutes." At this point I must admit that I was obviously not paying
attention because it didn't register that not enough oil had drained
until after I had replaced the filter and refilled it
with 3.59 qts
of new oil. When I was cleaning up and draining the oil from the
drain pan, the light finally went on and I realized that I didn't have
anywhere even close to enough old used oil in the drain pan. At that
point I went to the
computer and Googled for some help. Google was NOT helpful which is the
reason why I am writing and posting this. At that point, I had
almost double the correct amount of oil in the engine, it
needed to be drained down to the proper amount and at that time, I
still hadn't found
the real oil drain plug. I got the extra oil out and what remained
was about half old oil and half new oil. Later, after
I had calmed down a little, I was able to figure out what went wrong. About
two weeks later, I
rechanged my oil and filter again to get to a status of all
new, clean oil.
I will lightly criticize the Owners Manual and the Service Manual as
contain exactly the same drawing and that drawing does not convey as
much confidence as the Clymer photograph about being sure of the bolt's
location. If however, one of these was the only source of information,
then a person
would be adequately directed. I obviously did not notice nor compare
locations, 1) the location indicated by the Yamaha books vs. 2) the
shown in the Clymer picture. Anyone who does this comparison will
certainly notice the discrepancy. We are not expecting a problem on a
simple task like changing the oil. We look where the picture indicates
and find a bolt right where shown that has a brown washer. We remove
it, it is short, we get oil, all the indicators are correct. Except it
is the wrong bolt!
I am not aware if there have been different versions of this Clymer
Manual printed and if there are, which versions contain this
mistake. If you have a Clymer Manual, please be advised of
this problem and compare these two locations before removing any bolts.
Once a person is warned, the difference becomes obvious. It is
unfortunate that this wrong picture was published. The Clymer book is
an excellent reference. It is written in a style that works
exceptionally well for those of us that
only occasionally become mechanics and the manner of presentation is
vastly superior for non-professional mechanics. Even having the Service
Manual, I will continue to reach for the Clymer Manual for reference
because of the better style of presenting information to
non-professionals. If you work on this motorcycle, then I highly
recommend that you get a copy of this Clymer manual. This web page
documents an error, but overall this book is a very valuable
information resource that you should have available.

Notice that the location of the Oil Drain Plug is close to the side
stand. This drawing is shown from the right side of the bike looking
across underneath and slightly towards the front. If the drawing was
wider, the front tire would be on the right and the rear tire would be
on the left. (My engine photographs, above the Owners Manual pictures,
are taken from the other side of the bike.)
