90Bansheedude Posted June 29, 2015 Report Share Posted June 29, 2015 (edited) I finally got back to my project a little bit. See it at http://bansheehq.com/forums/index.php?/topic/146660-90-banshee-total-rebuild-project/ It may be only a little bit of progress here and there, but im gonna try to stick with it as life allows. I got it running and am trying to dial in the jetting. To my knowledge the motor mods are... Crank - Possibly, but not for sure Ported Reeds - Believe they are aftermarket Exhaust - Bills Pipes Timing - Believe it is approx 4 deg advance Air - K&N seperate direct mount pods Carbs - stock with 30 pilots and currently 340 mains Plugs - B8ES Stator and Coil - Believe it is stock Location - Nebraska Temp - 80F When i got it, it had a hole burned in one of the pistons and was jetted with 280's. I tried 300's then 320's and finally 340's and was not getting any noticeable bog or performance drop. I do think it is running cooler now, with the 280's it seemed to be hot. The brownish plugs were used but the jets were put in progressively larger until 340's. The plug chop was done with the 340's. It starts very easy and idles wonderfully with the speed screws barely lifting the slides at all. Idle mix screws at 1 1/2 turns out. What do you guys think about the plugs and plug chop? I am kinda thinking i could go richer yet, but at the same time, i think im there and going larger than 340 seems like too much for this setup. i want to make sure it dont burn up another piston but dont want to get it too rich. Looking to jet it decently or slightly rich at this temp so i can ride it at 100F or 60F without messing with jets. It also seems like the plug might be a little hot? Maybe should go with a B9ES or BR9ES (i think next time I order plugs, im going to get resistor plugs. I also need to get some proper plug cap/boots as these have no resistor protection either.

Larry's Shee Posted June 29, 2015 Report Share Posted June 29, 2015 60 to 100* is to much of a difference to not rejet, IMO. Have you leak tested? Quote Link to comment Share on other sites More sharing options...
90Bansheedude Posted June 29, 2015 Author Report Share Posted June 29, 2015 Yes I did, I even show it in my build link. I know its a stretch, but maybe a tad rich at about 80f, so that it will never be too lean. Or change that to 70f - 95f Sent from my SCH-S720C using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
