valve spring question for a 1925


Recommended Posts

hi all! i'm removing some carbon build-up and going to lap the valves on my 25 touring.while i have the valve springs out, i was going to check the tension on the springs. my question is? are there correct tensions on the springs, or are there specific hieghts that i should go by. thanks

I replaced mine when I rebuilt the engine. I think they are supposed to be 3 3/4" and I had some as much as 1/2" short! The deminsions are in the repair manual but I have set it somewhere and can't find it at the moment. I'll keep looking.
