How many miles on your bike when the caps gave problems?
THX.

Mine failed at 67,430 miles. Note though I never winterize so bike gets started every 2 weeks and left run for about 20 minutes. I'm sure that's not good for it.

Perhaps not good for the bum spark plug caps but good for the engine! I've used the same tactic over the winter which has kept the bike ready-to-go if an unexpected warm day popped-up.

Same issue. Glad I searched here, I have cleaned out valves, fuel lines, filters, tank and pump trying to fix this. Expecting new covers in 3 days. On the upside, my entire fuel line is . A huge thanks to you all.

I've been doing that consistently each winter since I moved to OH in 1990 and none of my Honda motorcycles have ever had anything fail! The naysayers theory is that heat from the engine causes condensation in the exhaust system but I've never suffered any exhaust system problems from the alleged condensation. And my motorcycles remained happy all the time!
