BansheeBrian Posted March 31, 2004 Report Share Posted March 31, 2004 I noticed some wicked casting flaws on my intake and exhaust walls.Would it be wise to grind them out or leave them be? It looks pretty rough in there! Quote Link to comment Share on other sites More sharing options...
350duner Posted March 31, 2004 Report Share Posted March 31, 2004 As long as you don't change the size or shape of the ports you don't have anything to worry about. Go for it. Just don't polish the intake. Also a small gain can be had by knife edging the intake bridge and any other "brick walls" the intake faces. That's considered a mild port.

Aussie Quad Racer Posted April 1, 2004 Report Share Posted April 1, 2004 Take note. Every bit that you grind or mod changes the way the air flows in that area. Quote Link to comment Share on other sites More sharing options...
BdBanshee Posted April 2, 2004 Report Share Posted April 2, 2004 Be careful and take it slow. Also, make sure you don't grind any of the sleeve away or it will have to be re-chamfered. Quote Link to comment Share on other sites More sharing options...
