Hey guys.. I just got cubs dune ported by Jeff@FAST. I had stock cylinders with some mild porting, and a 4mm stroker crank before I got the cubs. They pulled PERFECTLY on all gears. I had 330 mains and needle on 3rd clip ( I am at sea level ), on my 36mm mikuni flatside carbs.. Although, after I got the cubs with the same carb setup the bike no longer pulls at all. I mean it doesn't pull at all. For ex, I am on 4th gear going somewhat slow (not too slow at a point it will stall, but just cruising at 4th), then I pin the throttle at WOT, It would take like 4-5 actual seconds to actually start pulling and the hard pull to kick in, instead The bike just bog and slowly increases speed then suddenly pulls. My old cylinders used to pull everywhere, if I were to pin it from going slow it pulls. I have tried 330,340, and 350 mains and raised needle to 4th clip and still no pull on the cubs, I am running klotz supertechniplate oil at 32:1 ratio ( using premium pump gas) on 22cc domes. I would also like to mention that, for my air screw and pilots, well, I don
