I have an 87 shee. Since I have owned, it has never run like everyone says a Banshee should. Was stock when i got it, I put on Trinity single carb, 34 PJ, and a Dynaport 2into1 exhaust. This setup gave me a lot of rideability in the woods with great low end torque ( I also changed the front sprocket to a 12 tooth) I had tried jetting, tuning and everything else I could think of and it still was not the badass wveryone said it should be. I have owned and been riding since 82 so I don't think it is my riding style. Anyway, now I have replace the single carb with the stock duals and replaced the 2into1 exhaust with the stock dual pipes ( mostly so I can ride in my yard without pissing off my neighbors) Now I think the same problem exists as when I first bought it, I am not getting full burn in both cylinders all the time. It seems to be intermittent, sometimes left then right and sometimes both kick in as I can feel it when I ride and see it out the exhaust. The only thing I have not replaced is the CDI; new bore, rings, gaskets, reeds. I have obviously synced the carbs as good as can be done. Does anyone have any input? Is this a carb sync problem or a CDI problem? Tired of just keeping up with an LT250, should be smoking him, right? Help.

 

Hmmm, could be a faulty CDI or a bad pick up coil..... Have you done a spark test???? If not, do so and see if you have a weak spark..... Make sure all electrical connections are clean...

 

ya my guess would be somethimg that deals with the sparkplugs.

 

Do you mean, test for spark or test for spark strength. There has never been a time when I have not gotten a spark from either wire, and when I do a plug check, both seam to be burning just fine. ( light brown) Is there a specific test for the CDI that I am not aware of? Thanks for the info so far.

 

This might be a stupid question, but it has happened lots of times. Did you put the slides in the stock setup with the cut-away towards the rear? They will act very erratic and not run very well like that.

 

It's been awhile since I put it back to stock so I will check that. Sounds like a stoney thing that I might do. Thanks. I am also looking for a method to check for spark strength if anyone can help.
