Rustynail Posted September 17, 2012 Report Share Posted September 17, 2012 Anyone think these look ok? Need to go one way or the other? Looks a bit rich on the main. your ring is too wide and a touch too dark... Quote Link to comment Share on other sites More sharing options...
jsinar Posted September 17, 2012 Author Report Share Posted September 17, 2012 I'm about to run it +4 timing and the weathers cooling off now. That should be about right. Quote Link to comment Share on other sites More sharing options...
gwinnraptor Posted September 17, 2012 Report Share Posted September 17, 2012 It looks about 1 size too rich on the main. I like to run mine a bit rich, so id stay there if it were mine. Mines probably 2 sizes richer than "perfect". Quote Link to comment Share on other sites More sharing options...
jsinar Posted September 20, 2012 Author Report Share Posted September 20, 2012 One more question.. right now with 25 pilots, the screw is .5 turns out, and I have to pull the choke all the way to start it, but it starts 2nd or 3rd kick, if I go to 27.5's will that affect the main jetting also?

BansheeTeam Posted September 21, 2012 Report Share Posted September 21, 2012 This better? lol It's my first plug chop, more like a plug hack. But you get the idea..lol That's with no lid and 280's Wide open 1/2 mile 6th gear pass. It felt like it picked up damn near 10 mph, and the front fenders were bent back, very squirrley on top end, never been like that before. Your slightly lean there bro you might wanna bump it up a size or maybe two till you get a nice tan light brown color. You want my advice get rid of the airbox entirely run pods (UNI's or K&N's) with outerwears your gonna see a lot of performance gains overall and a lot on the top end if you jetting is right it should be around 310'ish with the pods maybe 320 im not sure but if your happy this way I'd recommend changing your fuel mixing ratio to 36:1 instead of 32 so you can slightly be richer. Running rich wont blow up your engine lean will so be careful. And good luck with your banshee! Quote Link to comment Share on other sites More sharing options...
jsinar Posted September 21, 2012 Author Report Share Posted September 21, 2012 I'm going to do a chop with 300s tomorrow and see what they look like. Cooler weather is here now, so the 280s would prob be too lean with no box lid. I've got some 290s on the way just in case. Quote Link to comment Share on other sites More sharing options...
RadarRacing Posted September 22, 2012 Report Share Posted September 22, 2012 Imo , those plugs are just fairly new with not enough pulls on em and the jetting looks slightly rich to me in both color that it will eventually end up at as well as thickness of the ring. I think you are a little long on ride distance. Maybe just do 3 or 4 good hard accelerating pulls wound out into 5 th or 6 th and you will probably see a darker ring. You would like to see a beer bottle brown color. Quote Link to comment Share on other sites More sharing options...
jsinar Posted September 22, 2012 Author Report Share Posted September 22, 2012 (edited) put my 300s in today and rode around for about 30 minutes, plugs were black as night, the 280s may be about right til it cools off to about 60-50 or so outside. Does the added timing and outerwears need to be compensated for any? Edited September 22, 2012 by jsinar Quote Link to comment Share on other sites More sharing options...
jsinar Posted September 23, 2012 Author Report Share Posted September 23, 2012 (edited) Alrighty, did another chop with about +2.5 timing, 85 degrees outside.. Still looks rich, but there was no bog top end. Figure it should be good til about 60 degrees or so.. 2 passes, 6th gear wot, held it for about 7-10 seconds each pass.
