OK This is not about pointing fingers at anyone, just to share what happened to me. My Bike is the 2017 300 raga version. It was bought by me, used 29 hours on it total, as of last night. The original owner I bought it from, actually was able to get the GRO branded oil, and he put it in the bike, I assume since new. He solemnly swears that he put the hour meter on the bike within minutes of unboxing the bike. When I got the bike the meter showed 17.7 hours. I noted the clutch seemed to have what I call chattery feel to it, like warp or something. Rode it, adjusting only clutch lever to my liking. it never got any better. so then, bike is at 20 hrs. I changed the oil to Yamaha's 0w30 like we used in all the gasgas's I have had since the 04 models (after been steered away from the GM Autotrack debacle). So, once this oil changed, the end result was the fiber plates decided to dissolve off the clutch packs. FWIW the cluch is made by S3 (least that is what is stamped on these replacement ones I got more or less directly from our TRS importer). THe fiber plates from my inspection are (compared to the gasgas clutch kit sitting on table next to my clutch) are identical. the metal plates are tiny bit thicker, but still mostly the same (could swap the fibers if needed IMHO, but the steels you cannot). the finger height with new pack installed was 15.3 mm, when I took my (unknowing at the time were dissolving) finger height was 17.5 easier to pull but would NOT even hold the 1st gear (aka means that I didn't have to pull the clutch to come to a stop in 1st gear). new clutch is smooth engagement, seems to be fine, loves the yamalube synthetic we have always used. FWIW, GRO oil was in the manuals I got off the internet, but wonder if that oil and oils most of us have, are somehow incompatible, or if I just got lucky and got 1 of the MFG'd badly set of fiber plates, by luck of the draw? It was one of the plates that actually was able to dig the material off with a fingernail. you know, one in a hundred MFG defected set of fiber plates or something? dad and a friend of his, bough 2013 model raga with the serials being 1 or 3 digits apart and from same US shipment we picked up both bikes in crate the same day but, that friends bike had the bad crank bearings (rattled and replaced by factory warranty) where dad's did NOT have that issue.
