The scoot was due an oil change. That was the easy bit. The Black 400 four failed its MOT last week due to a bent rim, so off it went to the very nice wheel man. Saturday comes around and I get the dreaded call - the rim cracked when he tried to straighten it. Grrrrrr. While the bike is up on the stand I pulled the back wheel to get rid of the ugly stainless trim on the sprocket .... hmmmm.... looks like a new chain and sprockets might be a good idea. David Silver wins again, might as well get a lift handle and brake pads. This is going to cost.
