I'm rebuilding my 89 RMX250 and noticed the new cylinder has an exaust bridge are these relieved from the factory now? Also I'm using a std suzuki piston is it nessary to drill holes to cool the exaust bridge or is that a bit of a wiesco only thing? I would rather not do it as I've allready put it all together and I don't lke the idea of drilling holes in cast pistons!
