NGC Drive Chain slap. NGC

Miss my shaft drive after I see this.. is it normal for a chain to slap around like this?

I have the slack pretty close to what the book calls for..

From what I've seen in the past, yes, it's fairly common, especially on long-travel swingarms.

Normal.

WOW.

I have never seen that perspective before, nor have I looked..

Is the chain actually making contact with the swing arm at times ????

There are plastic guides on the swing arm, they need to be replaced occasionally as the chain wears grooves in them. If let go long enough, I've seen pictures of grooves worn through and into the swing arm.

It looks like the bike is a 650 single and unless you know how fast it was being ridden and importantly on or off the throttle its hard to say. On the throttle the upper chain run is tight and the lower is where the slack is. Assuming the bike is on the gas and not being lugged along then I'd put my money on a chain with a tight spot in it. fairly common on a chain tha'ts done a lot of miles. It shouldn't be like that though with a decent chain and ridden sensibly.
