wierd spuddering after long ride

[rtcc]

Hey guys,

ok so for the last few weeks I have really been trying to get my jetting right and after numerous plug chops and trial and error I think I have her set up almost perfect. She runs really good through all gears and I can hit the trails and mid throttle stuff without fouling plugs like I used to. I havent got a bunch of time on it but probably 10 rides of about 30 minutes each. Whats wierd is my last two rides after riding hard for about 20 minutes all of a sudden it will just start sputtering in mid throttle. It does it through all gears and it did it all the way home (about a mile). So I shut it off, let it cool and checked the plugs. They look almost perfect (I know its not the best way to tell) but I mean they werent wet and fouled all black like they used to be when I ran rich. So I put them back in and it started fine and ran fine. Then the next day I took it out again and after about 20 minutes it did the same thing......and then my clutch cable broke so that was the last trial I could do. I got a new cable tomorrow so I will put it back together soon.

 

But what do you guys think it could be? It doesnt feel like it is going lean, it doesnt backfire and spit like its lean but its not a full blown woooooooo bog either. Its just kinda off and on with no power, but the higher rpms run pretty good. Not perfect but pretty good.

 

oh tors is unplugged and mods are only fmf gold pipes and K&N with no airbox.

 

I am having some electical problem somewhere cause my lights arent getting enough power to light up.

 

thanks for the help, I am jumping back into banshees after a 5 year break and I dont remember much about whats going on.
