Checking Drive Chain Slack

[Aussieflyer]

How do you check the wheel alignment Aussieflyer?

Townie, I use method B, but I've seen method A used and have wondered whether it is actually correct.

Taking Aussieflyer's and my approach may end up producing a roughly similar result. Using method B, I aim for 25-30 mm of slack as my seat-of-the-pants assessonometer tells me the bike's smoother when the chain is tighter. What would that slack then be if I used method A? Possibly about what Aussieflyer aims for. If I used method A and went for 25 mm of slack, would I end up with a chain that was too tight?

Looking at the illustration in the owners manual leads me to the view that Honda recommends method B. Certainly, if I am aiming for 25mm slack I'd be more inclined to use method B.

Not sure that helps really.

Just by measuring the axle position in the swing arm.


I checked the accuracy of the adjuster blocks when I swapped out the mags for the wire wheels. Fitted the mags back on on the bike with no tyres and used a couple of long straight edges to compare rear wheel alignment to that of the front wheel. Turns out the markings on the adjusters are pretty good but I find them more difficult to read than my trusty steel rule. In this photo you can see the measurement is set to 28mm which is then easily compared to the other side.
