I finally found something that Suzuki did really, really wrong on the C50. In practicality, you need to remove the cover to inspect the coolant level.
What led me to this conclusion was that after I got the bike back from the dealer after having the valves adjusted and a general pre-season check over, I though I noticed the odor of a coolant leak. I let it go at first, thinking probably some fluid had been spilled on the motor. A few days later it persisted, so I checked the things I could.
The owner's manual shows how to check & top off coolant, but doesn't say if it should be done when the bike is hot of cold. With the bike cold, the level was down below the "low" mark, so I filled it up to the "high" mark and went for a ride (see yesterday's 'first ride of the season' topic). At first I thought I got a whiff of coolant, but it went away as the ride went on.
Today, when i got home from work, I immediately popped the cover, and the fluid level is down to just about the "low" mark. Again, do I check hot or cold?
I'm trying to establish whether or not the deal might have left a clamp loose or something, or if maybe it was just overfull when they gave it back.
TIA for any advice.
