So little background:
I bought this bike from the dealer with 300 miles on it, it now has about 11.5k. The bike is stock, I ride it almost 98% in STD mode and never in A mode. I did mainly commuting with it, and about 100-200 miles of canyons on the weekends. I changed the oil 4 times since I bought it, but just had the 4th oil change sampled by Black Stone Labs in Jan 2018. Came back with what they considered high aluminum content. They suggested it might be from the transmission or cylinder walls...I just chocked it up to a new engine still breaking in.
Fast forward to now. I am always pretty picky about they way my shifting and clutch feel, so I am now about a 1500-2000 mile oil change interval, always running 20-50 yamalube. Next change in a month or so will be 10-40 yamalube. I will have that sampled too just to see what happens.
But heres my problem, seems like when the bike is warming up and the oil is still cold, if I am even remotely hard on the clutch during a launch from a light, it makes this horrible grinding, screeching metal on metal noise like all the clutch plates just ground against each other the wrong way or something. (it sounds like you scraped the exhaust on a curb or something) Engine sounds fine, runs fine and has normal power and the clutch doesn't slip under full power once its fully out and locked up. Once the oil is warmed up, it seems fine and can launch like normal.
Admittedly, I have done a few burnouts, but only like 5 or 6, nothing that I thought would fully destroy the clutch. And I don't do clutch up wheelies or anything like that.
My 1 year warranty is up on feb 18 2018, so it would be awesome if I could still use that for this issue, but I have a feeling the clutch wouldn't be covered anyway.
I will try and post a video of it when I start and run it tomorrow morning.
I am also contemplating swapping out the stock clutch for an xsr900 slip and grip clutch ($214), so this might be the tipping point because I kinda wanna tear the cover off just to see what the clutch looks like.
What do you guys think? Anybody else have or heard of nasty clutch problems like this?
