[QUOTE="Dazza, post: 1459806, member: 99768"] Hi, I have a 2015AF FJR1300. It was purchased by a friend as new, old stock, in 2017. He only did 3500kms in the 5 years before I brought it. It spent most of the time in storage. It was serviced every year, for the 5 years he had it, inline with the warranty requirements. My problem is the drive train crashes into gear very loudly, when 1st gear is engaged while the engine is cold and on high idle. The problem does not exist when the engine is hot and idling at 1100rpm. I have changed the diff oil, engine oil and filter, hoping this would help however it hasn't. If I try to gently put it in gear you can hear cogs catching each other and chattering. I have tried dropping it into 1st gear abruptly and this generates a terrible crash sound. The clutch is always smooth, no slippage or shuddering, whether the engine is cold or hot. I am suspecting that because the bike sat for 2 years before being sold and that my friend hardly rode it, the clutch friction plates may have dried out and so are needing changing. Has anyone had this experience and found a solution? I'd really appreciate informed feedback on what may be going on here and how I can resolve it? My friend always warmed the bike up before riding it so he never experienced the issue I found. A second observation is that when the bike starts cold, the idle rpm is about 1600rpm, which seems very high to me. Once warmed, the idle rpm is 1100rpm. Are these typical rpms for this bike? Thanks everyone. [/QUOTE]
