Hey guys I want to know what everyone is using to cut there ports (like increasing exhaust timing) so there will not be any burrs left on the inside of the sleeve. I am using a fine grinding bit in my dremel. Anybody using something that leaves smoother cuts? Or is there a good technique for removing burrs?

I am using fine cut diamond needle files only ( longer, but for sure straight). After cutting I am using hone ( bought in Automotive store) for cleaning burrs. I always do it with hone-it is not realy scratching chrome, but remove all hangings easy.

hone
 

Edward I bet you using a wheel cylinder hone arent you! :D

:nod: All I know about modding engines is to leave it to the experts. I just love the results, thanks Edward! :nod:

Definately a lot of Palmaris Racing guys on this forum. Things keep going as they are and myself and TopGun will have to start organising Palmaris Racing cup events:lol:

Guess you have to go where the power is:nod:

Re: hone
 

I think this is what it is. I know the minimum size is 13 mm and open till I belive 50 mm, seems like it is. But it is perfectly fit in our sleeves. There is two kind, one is Aluminium oxise and other is Silicon Carbide. I am using aluminium oxide-it is softer and doesn't hirt chrome. Silicon cirbide will scratch chrome. It costs like $ 15.
Just insert it in sleeve and turn around 3-4 times-it is ready. :nod:

Hi Richard. You are very welcome. Keep it run, she is not ready yet, needs some more run time.;) :nod:
