ported-jetting

[Toomey Banshee]

Picked up a ported bike from NYUK. Real nice machine. When I got it the guy that had it before had 340 mains, 30 pilots, dyno-jet needles on the first clip-towards the blunt end. It has stock carbs, K & N pods and fmf ssts. It ran like dick. Over the past 3 weekends and countless hours I have come down to this -290 mains, 27.5 pilots and needle 2 down from the blunt end. It sounds way way small to me, 290's, but the plugs look pretty good, a nice tan color. Anything else I should look for? On my 99 with air-box, no lid stock port and carbs, pro-design foam I'm running 320's, stock pilots dynojet needle 3 down from blunt. I would think K & N's would require larger jets? I just dont wanna blow up the new bike. Any suggestions?

On your 99 I assume you're running Toomey's, from your screen name? It seems that many people with SST's run a sizeably smaller main, than most with Toomey's. You can see what I'm running in my sig. If it has been improving as you come down, and the plugs look good, that's hard to argue with? You also have to remember that every bike is probably going to be a little bit different. It sounds like your checking everything you should keep an eye on and it's running better, I can't argue that.

I usually have great luck w/ 290 mains, 4clip from the blunt end on stock needles, stock pilots. Pulls hard as hard from the bottom all the way up w/ no bog. Never tried the dynojet needles though.
