Question about OS V spec. !!!!!!!!!!!!!!!
I have about 7 or 8 gallons of 30 % nitro through my OS V spec and it still runs great but just recently it feels like it is losing it's "pinch " not complaining at all because it has been and still is a awsome motor but when or how do I determine when it is ready for a new "piston , rod , sleeve " ???? I twist it over and it feels weak but it still runs good ? I don't know what to do . Thank for the replies everyone !!!!
