Puzzling engine noise
Posted July 31, 2001 - 12:35 AM
The noise disappears if I rev the engine a bit more (change gears) or if I let go of the gas. I have tightened every bolt I might suspect of causing this, but I'm beginning to suspect it's from the engine... Could it perhaps be the cam chain tensioner that needs a look? Anything else that can cause this?
The bike has been run nearly 10 000 km, mostly on roads and some gravel pits/forest trails.

I'll be sure to take a good look at the drive balancer gear key -- sounds nasty.
I'm not too sure about the sound being related to valve clearances (I checked them recently) or wheel bearings, but I'll have a second look anyway.

Living in Norway, some parts can take quite a while before they arrive. I'd better get everything right the first time...

all you will need is the key.
its just a little square piece of metal
you can have it built at any machine shop cheap & fast
they are exactly in inches
.196 square by
I used keystock
these are nice and snug
I took mine apart twice and still used the same gasket
here are the yamaha part numbers.
balencer drive gear part# 5BE-11536-00-00
Straight key part# 90282-05034-00
the gear was about $50.00
the key was about $1.20
both items were on backorder in the U.S.
so I had to make my own key
and waited three weeks for the gear

its not the right way to do it but was cheaper and I did not notice any reason while there to replace them
if you are going to buy them there is one on the clutch basket and the drive balencer gear you will have to remove
