jrod Posted June 4, 2010 Report Posted June 4, 2010 SO i just got my new Dune Ported Cylinders with T5's, Stock Carbs, K&N filter in the stock box, Timing plate at +4, Boyseen reeds with spacers, Noss Cool Head 19cc domes. Just wondering what the close to right jet size would be. In Oklahoma about 1150elv. Quote
okbeast Posted June 4, 2010 Report Posted June 4, 2010 I'd check with whoever did the jetting, they'll have the best idea. But I'd say a 330 or 340 main would be a good starting place. Quote
jrod Posted June 7, 2010 Author Report Posted June 7, 2010 well pulled the carbs and they have 290's in there. I will get some bigger. Quote
Erwin8r Posted June 8, 2010 Report Posted June 8, 2010 290's are way too small... Most "dune ports" are closer to "drag ports," so you'll want to err on the side of a bit rich... Quote
06specialedition Posted June 8, 2010 Report Posted June 8, 2010 I run 320's with my port job....but you are at a different elevation so that may change things a bit. Jump a few sizes and check your plugs. Quote
jrod Posted June 11, 2010 Author Report Posted June 11, 2010 Ok, So i will get some bigger mains. But what about the Pilots?? Anyclue? Quote
pr0blumz Posted June 11, 2010 Report Posted June 11, 2010 Ok, So i will get some bigger mains. But what about the Pilots?? Anyclue? 27.5 pilots Quote
jrod Posted June 11, 2010 Author Report Posted June 11, 2010 Thanks, For all the info and help guys. I will be jetting the bike soon. So lets see what happens. Quote
