Yamaha Balancer Mod Tech Papers
Moderator: rztom
Hybrid, not to throw a wrench into any of this but,
#1 is the lower (next to flywheel) cylinder, thats how I think everyone looks at it.
Yamaha has the upper left as #1 and the cylinder closest to the flywheel (lower left) as #2
are you using Yamaha's way, or the other way, it just seems like everyone looks to #1 as the lower left.

hybrid your picture are very helpful. but I still have a question.
If your pictures are right my RZ500 has been setup incorrectly by the previous owner.
It was setup like yours except the balancer shaft gear mark has been lined up with the punch mark with the X through it.
Are you still happy with your results?

Balancer Shaft - HELP explain this clearly once and for all
Having read all the above posts, no one can clearly follow how to do this modification in setting up the crank balancer shaft !! ??
I now have the above two report sheets, plus another YAMAHA TSI Report on the 1984 model.
(I really wonder if there is any actual difference between the 84 & 85 balancer shaft )
These reports leave you not knowing what is right or wrong = confusing to say the least.

The link to the clear images of the gears in question are a great start to resolving this dilemma once and for all.

Re: Yamaha Balancer Mod Tech Papers
i have a magazine that says . the most disappointing aspect of the motor is the rumble that emanates on trailing throttle between 4500 and 7500. backing off at around 6500rpm produces behaviour reminiscent of running over a pile of bricks
i have 4 Rzv500s now all of them bar one bike vibrate to some degree
one bike feels like a well put together 4 stroke . its amazing how smoothe it is at all rpms . i have not had this bike apart
so doing this mod might not change anything at all
i thought the later bikes that were driven off the other crank had a funny fly wheel on the end aswell to even things out ?
