Disclaimer; This is not my bike and the friend who owns it had a nasty fall down some fire escape stairs so hasn't been able to ride, or really walk, since it last went out. Last ridden Nov 29th on very salty roads. This weekends tinker was resurrecting a Gladius which had seized solid. Side stand wouldn't retract, all 3 brakes were bound on and there was an unlocated oil leak when running.
3hrs with the cleaning products, tiny wire brushes etc and we had her back to life. All brake pistons pushed back OK, pads came up useable with aggressive wire brushing and somehow, by an act of witchcraft, the chain only had one slightly stiff link which was the joining one. It was a very new chain so only really surface corrosion on side plates, no blown x-rings fortunately.
The oil leak was diagnosed as the salt corrosion having eaten a pin prick hole in the oil filter housing so, since it needed a service anyway, a free recovery.
Apart from all the curry and wine they now owe me for labour rates 🤣
* Being a Suzuki, it did however start first push and run like a sewing machine.
