I'm at 28,4XX miles on my '99 LT that I bought back in February with 21k miles.
Had the full-blown 24k service done back in May - all fluids renewed and otherwise baselined this bike for service purposes. When I got the bike back from the Mortons Service department, the service manager mentioned I might need to add distilled water periodically until the coolant level stabilized. He said distilled water was just fine as they had roughly a 60/40 coolant ratio in the bike,and adding a bit of water wouldnt compromise the mixture.
I commute about 72 miles on this bike 3 or 4 days a week, here in the DC area.
In recent Months, I'm finding I periodicaly need to add a wee bit of water to bring the coolant up to the minimum line. "Wee bit" being defined as literally a quick splash of distilled water into the overflow tank under the seat.
I have no evidence of leaks, coolant in oil, or exhaust. It has been a hot Summer, and I do encounter stretches of stop & go traffic...
Question is, it seems 4k miles is a long time to stabilize my coolant level -- Is this normal?
