No damage.
I was wondering something, does it matter how fast you go? I live in the mountains and often times I will hold in the clutch lever, kill the engine, and glide down the hills. I can reach speeds up to 40+ miles per hour gliding down these long steep hills with the engine off. With the sprocket spinning that fast without the engine running and oil flowing could it damage the clutch or engine? Should I put extra grease on the clutch or anywhere else?
