... With the bike on the main stand, rear wheel in the air, if you put it into gear and let the rear wheel turn with the engine just ticking over on idle the rear swing arm chatters for side to side like you would not believe (in a twisting movement) and the whole bike dances around on the main stand...
If the chain has been that tight for a couple of hundred miles plus, I would also be concerned about the bearing and the drive shaft that the front sprocket it attached to - would be worth checking if there is excessive play in the shaft now...just a thought.
@Darrsi, I really hope your right!! It's not just the chain slapping around though when the rear wheel is running on the main stand, the whole bike dances around, it's really quite alarming to watch.How many miles did you have to put on your DID chain before it broke in?Thanks!!WTFnow!!
Darrsi and unfazed, thanks again for the ideas and the link to the other thread, It does seem to be a common problem (the whining) with the heavy duty chains. I'll pass on your ideas to my mate and I'm sure he'll check all the wheel bearings etc again to be sure. My friend has over 40 years experience working with bikes, he's a very knowledgeable guy and with your help and his, I'm sure we will get this problem sorted out. I'm tempted to get a not-so-heavy-duty chain and fit it on there just to see if the noise goes away. I noticed that the links on the DID chain are flat and parallel on each side, but the OEM chain that was on it before had links that were concave on each side, not sure if that really makes any difference though, probably not.
