Chain Adjustment Question...

[rvbiker]

Ideally you wanted to be seated on the bike in your normal riding gear ay nd have a buddy check the slack. This is the best method as when your swingarm moves through its arc the chain will tighten as the arm compresses, then once it passes the peak of the arc the chain will slacken.

Pete: I agree with this actually but where is this recommended? I haven't found it in the users manual or anywhere else for that matter. Personally, I adjust my chain so I don't feel any chain whip when applying the throttle but that's just me.

Hi,
I found the recommendation in the user's manual. It's in the "PERIODIC MAINTENANCE AND MINOR REPAIR" section. Here's what the manual says:

Drive chain slack
The drive chain slack should be
checked before each ride and adjusted
if necessary.

To check the drive chain slack
1. Place the motorcycle on the centerstand.
2. Shift the transmission into the neutral
position.
3. Spin the rear wheel several times
to locate the tightest portion of the
drive chain.
4. Measure the drive chain slack as
shown.
Drive chain slack:
45.0–55.0 mm (1.77–2.17 in)
5. If the drive chain slack is incorrect,
adjust it as follows.

Hope this helps.

first of all welcome.... now as far as the chain goes this is what i would add to the thread. A friend of mine who has his own shop and has raced for awhile told me to have about a 'dime' distance of slack. Meaning when u move the chain up or down it should only move vertical about a 'dime's' width. make sense? this is an easy check that i do pretty much every time i get on the bike.... takes all of 2 seconds to check and its easy... hope this helps


this maybe wrong and im sure someone will correct me if it is but this is what i do and im not changing maybe i should be ed haha

does that put you within the yamaha spec? it either does or it doesn't but if I had to guess I'd say that sounds a little tight.

I just use a tape measure.
I make sure its over 1 and 3/4" and under 2" of slack.

I also use a tape to align the rear wheel. just make sure the distance from the center of the swing arm pivot to the center of the rear axle are the same on both sides when the axle nut is tight.

It seems like a lot of slack but its right when its loaded.

I was wondering what to do about aligning the rear wheel.. Thanks

Sounds like you guys so far have it easy, mine didnt come with a centre stand, and i have to admit i havent checked it. I think that is a job awaiting me. Just have to work out how to get in air.

Carport beams and ratchet tie down straps through the grab rails onto the swingarm. Great for adjusting and aligning. To much trouble for lubing though.....why couldn't they just put on a centre stand like every other bike I've owned?
Cheers

oz isnt the idea to get the weight off the swingarm??

[aussiejules]

OK guys really do we need weight off the swingarm. The manual says have rear wheel airbourne, but not whether you have to have the arm free. Do i need to support under the centre or can i use my race stand. I have just read every thread on chains and this isnt mentioned. The ass manual says have both wheels on ground.
