Not sure if this has been covered as of yet but here goes..
Referencing my 2022 Service Manual for the RL I noticed that there was a spec change for the chain slack from the pre 2020 models.
2019 to 2020 models was 25 to 35mm slack measured from the upper swingarm surface, whereas the 2021 & 2022 models are now 55-60mm
I have been keeping my chain adjusted to the proper 55-60mm spec (2 1/4"-2 3/8") and have noticed its holding adjustment nicely.
I also remember the chain being way out of spec (3.5") when I first picked up the bike about 360 miles ago, and went to correcting this day 1.
I am also noticing that the rear wheel is difficult to rotate when on the stand doing maintenance (chain cleanings & the like) and when I say difficult I mean decent amount of force, and getting about a 1/4 turn rotation, whereas the front freewheels nicely.
Removed the rear wheel and checked everything, re greased the axle & spacers; checked that the rear brake wasn't dragging. Not too sure what the culprit is, or if this is a normal tendency of the bike.
I have been taking the chain slack measurement per the service manual at the end of the top chain slider (upper swingarm surface, not on the slider itself). Lifting the chain firmly and measuring to centerline of the chain.
Am I going about this the right way, am I missing something by chance?
New to this bike and any enlightenment appreciated!
