The pursuit of peak engine
efficiency and economy can
drive some motorcyclists to
the brink of frustration.
Yamaha owners,
however, need only
drive to the nearest
Yamaha Dealer'
ship for a Genuine
Yamaha Tune-Up Kit. •
Each kit contains exactly the
right parts for a particular model
and year of Yamaha motorcycle.
There's no guesswork. No need to
rely on a parts counterman who
insists,"These are close enough:'
Also, there's no risk of
getting inferior parts.
Our points, condensors and
spark
plugs are the finest avail,
able anywhere. Or we wouldn't be
recommending them in our new'
bike warranty books.
Of course, the surprising
thing is, this extra convenience
and precision doesn't cost extra.
We even toss in a free gap gauge
and wrench.
So look for the yellow and
black GenuineYamaha Tune'
Up Kits. It could be the most
economical way to attain peak
engine economy.
