maskmanLS6 Posted February 4, 2013 Report Share Posted February 4, 2013 I have some cylinders that are ported pretty heavy and wanted some input on what the characteristics Will be, they have some killer looking work done but the port roof measurements have me a little concerned. The exhaust port roof measures 25.4mm from the cylinder deck. And the transfer ports measure 41.2mm from the cylinder deck. That sounds kinda short to me, could they be over ported for any normal riding? Quote Link to comment Share on other sites More sharing options...
lms1977 Posted February 4, 2013 Report Share Posted February 4, 2013 they will be good for only drag racing probably.. if I did the math right you should be somewhere around 200/129 on port timing with stock crank, trail riding will most likely suck Quote Link to comment Share on other sites More sharing options...

maskmanLS6 Posted February 4, 2013 Author Report Share Posted February 4, 2013 Yea im afraid their gonna be top end monsters, i do plenty of drag racing and dune riding so Im gonna try em out and see. Should they be pretty strong in mid range? I know the bottom end is out of the question but Im hoping for some mid range. Quote Link to comment Share on other sites More sharing options...
2strokes4u Posted February 4, 2013 Report Share Posted February 4, 2013 Could someone inform me on where the different type of port jobs begin as far and the port timing. looking for more of a range that determines trail, dune, port..

2strokes4u Posted February 4, 2013 Report Share Posted February 4, 2013 I have a set and looking to see what port i have. Quote Link to comment Share on other sites More sharing options...
maskmanLS6 Posted February 4, 2013 Author Report Share Posted February 4, 2013 You Will need to take some measurements from the top of your exhaust port to the top deck of your cylinder And from your transfer port roofs to the top deck of the cylinder. Those measurements can tell you a lot from what Im seeing. Quote Link to comment Share on other sites More sharing options...

badassbanshee479 Posted February 6, 2013 Report Share Posted February 6, 2013 Try a 4 mill cub on Alky with an over ride that was a handful in the trails! Quote Link to comment Share on other sites More sharing options...
oldskool Posted February 6, 2013 Report Share Posted February 6, 2013 I think it would be nice to be able to port my own cylinders. These folks say its easy. I kinda doubt it. <a>www.racelogic.com<a/> Quote Link to comment Share on other sites More sharing options...

Learn to slip the clutch and it's doable. You won't have much midrange brother. I'm not really happy at the moment with my set-up but you have it easier in the dunes.
