lyssad2003 Posted January 8, 2016 Report Posted January 8, 2016 Hi All, I'm on here for a friend and I'm really not sure where to start... I know you guys have probably seen/heard the same question/issue over and over... So I apologize in advance... but, here goes: Picked up a 2004 Banshee. Has 18cc heads from Trinity (I assume these are "cool heads"?), unsure of the bore (assuming .050 over). Vforce reeds, Toomey T-5s, K&N filter, stock carbs, but re-jetted. Also has a Dynotech F.S. Digital Ignition and some other piece that says stock with two up arrows, curve 3 with an up and a down, curve 2 with a down and an up, and curve 1 with two downs. (I have a feeling this is where the issue may lie). I am not sure if it has TORS removed or not. I can get a picture of the carbs tomorrow and perhaps someone can tell me? The issue is: the right cylinder isn't firing. We figured it was a fuel issue, so he cleaned/rebuilt carbs, re-jetted (340 main, stock pilots, I believe), and, of course, synced the carbs. He has checked the reeds, the tube between the carbs, checked compression (150) and spark (both good, so shouldn't be the coil...), switched the spark plug wires, checked the slides in the carbs, checked intake boots. I can definitely get more information as requested. Thank you so much!! Quote
Shee_fast Posted January 8, 2016 Report Posted January 8, 2016 More than likely it has tors kit off it...but I'm no ignition guy so I'm about the curves...but make sure slides are in correct..the cut away to the air box on bottom of slide.. Sent from my VS810PP using Tapatalk Quote
wayne_smith97 Posted January 8, 2016 Report Posted January 8, 2016 Your jetting is a little wacky too Quote
sleeper06 Posted January 8, 2016 Report Posted January 8, 2016 Jetting is rich if not ported but with unknown new to you engine you need to do some checking. You said you checked compression, you need to perform a leakdown test it could be an airleak on that side. Now I fell your compression is low for those mods Quote
ClaudeMachining Posted January 8, 2016 Report Posted January 8, 2016 (edited) What's the look the right plug? Wet or dry? Did you remove the right plug and with the cap on, check if you have a spark when kicking. Edited January 8, 2016 by MMAxtreme Quote
lyssad2003 Posted January 9, 2016 Author Report Posted January 9, 2016 Sheefast - yes TORS has been removed and he has triple checked slide position Wayne - the jetting is definitely a little wonky. Kinda playing with it, I guess. It has had this issue since he picked it up. Been a slow moving process to figure it out. Sleeper - he will perform the leakdown te st this weekend... as to compression, he seems ok with the number, but I will relay the concern. MMA - he is going to check this out tomorrow as well. Too dark and cold to do anything else tonight. Thank you guys for your input!!!! :-) Quote
wayne_smith97 Posted January 9, 2016 Report Posted January 9, 2016 Do you know if your motor is ported?? If so what kind of port? Quote
sleeper06 Posted January 9, 2016 Report Posted January 9, 2016 I build these motors quite frequently, with those domes your in race gas country and I usu see more static compression even with drag porting. I run similar domes on alky. Leakdown is a must. If your seeing those low static numbers and jets were a 340 I'm gonna go on a limb and say it's pr ported . Worth checking Quote
