99LRDblaster Posted April 2, 2004 Report Share Posted April 2, 2004 well i am rebuilding nowusheeitnowudonts 97 shee and i had to polish up his head chamber and exhaust port because of excessive carbon buildup and parts of the piston melted to it. i know the head getting polished wont give it any HP but it will resist the carbon building up on it. however do you think polishing the exhaust port would give it any? pieces of the piston were embedded in it so i took a dremel and got the piston out of the port and then i started with 220 grit sandpaper and worked my way down 400, 600, 1000, 2000 grit. it is really nice and shiny now and would resist carbon nicely. do you think the gases would flow bit better out fo the cylinder? also while his banshee is out i want to polish the outside of his cylinder. do you think starting with 220 and working my way down to 2000 grit will get a nice shine out of it?

mrmatt Posted April 4, 2004 Report Share Posted April 4, 2004 When I polished my exhaust port, I also cleaned up the intake side a little. I definately felt a difference, but since I did both at the same time, I can't be sure which one did the most good. If I were you, I would polish it a little more. 2000 grit probably got it really smooth, but you should get a felt tip and use some polishing compound to make a mirror finish. The felt tips are available from Eastwood. If you don't want to order the felt tips, then you can wrap a piece of cotton terry cloth around a sanding drum and apply the polishing compound to the cotton cloth. But if you wear through the cotton and let the sanding drum touch the wall, then you are back to square one. Quote Link to comment Share on other sites More sharing options...
