Thanks I got it

I'm trying to adjust my needle clip in my 34mm pwk keihin carb, but i can't figure out how to take it apart.... the spring inside is really tight

I'm trying to adjust my needle clip in my 34mm pwk keihin carb, but i can't figure out how to take it apart.... the spring inside is really tight

Thanks for the help! I was hoping it would be something else so I could save a little money but u got to do what u got to do. Cdi it was!!

Finally figured it out!! I decided to split the cases and inspecting everything, everything was good but had to hone cylinders for new pistons and rings, put all new seals and gaskets, put a new ignition coil, stator and flywheel....literally inspected every inch of the bike, repacked exhaust and... Same problem, the coil was weak when I tested it so I knew that for sure but the stator looked cheap and I had to tighten it before I installed it.Same Issue. So I replaced the only thing left to replace.. the cdi box, and it worked as far as firing on both cylinders put seemed to have no power.. put back on stock stator and flywheel (after cleaning rust off) and back to normal!! Running better and faster than ever!!

Ok.. I'll just have to find some one else who has a banshee.. I was trying to diagnose it before I start ordering parts I don't need..

I'm having same problem!!

Is there a way to test the cdi? And I only have a single carb.

Yes I do have a spark tester. I'll try it while revving up. Thanks

Here's my mods.. then the problem... fmf fatty powercore 2, pro design cool head with 22cc domes, bored .010 over, wiseco pistons, trinity 2-1 intake system with single 34mm keihin carb, k&n air filter with outerware. I had these mods for 4 years with zero problems! Went on a four day trip to the dunes at little Sahara and ran perfect for first day and a half! Then .... Just flying thru the dunes and it cut out on one cylinder. we've switched wires, changed plugs, cleaned and rejetted carb, checked stator and flywheel clearance, checked for rust, no rust, checked compression, had 125 on right and 123 on left. Checked reeds, switched reeds, same problem. Checked spark, good spark both plugs, checked for air leaks, no air leaks. Here's the weird thing... Runs on both cylinders on idle... And idle only. As soon as you give it gas, left cylinder dies... If you slowly rev it up it will hold for a few seconds, then dead cylinder.. Please help!!! This is driving me crazy!!!
