My Evo used to do it, until I installed an Arlen Ness Big sucker air cleaner. It vents the head/oil vapors directly into the carb's venturi, and not just into the aircleaner housing, like the stock unit does.

Drips are gone.



Correct me if I'm wrong, but you should be using a MINIMUM of 20w50, not 10w40..... too thin.

Thanks Dave... maybe thats the issue. I'll switch to the 20w50 and maybe that will solve the issue. I'll also look into the Arlen Ness cleaner... I bought the case of 10w40 during the winter based on the Amsoil reps recommendation. Is it safe to assume that the 10w40 is good for the colder months and I should use the 20w50 for the hotter months?
