500efi maint. quest
 

In hear that 50hr valve spring change will freshen these motors up. What other recommedations are out there for the 50 hr interval.

If it aint broke don't fix it!!!!!!!!!

Seriously, I have 140 hrs on my 500efi and only clean the air filter and change the oil. Actually I need to clean the fuel filter??? do that this weekend.

I was told by Fountain that the 500efi, if babied and proper maint. should have at least 1000 hrs with no problems????:cool:

ditto - Mine have 120 hrs.
