OKAY, my buddies banshee has been giving him hell for the past year or so. He's tried everything, has been to more than one mechanic, and has spent plenty of unnecessary money to get this thing running right.
Breakdown:
The bike kicks over and idle's perfect, has absolutely no powerband when it gets going. You can pin the throttle and I will pick up speed VERY slowly, but once it's in the upper rpm's ( whenever it decides to get there) it pulls hard. Sometimes it doesn't even want to hit the upper rpm's. It's like a banshee with a governer on it.
Mods:
Dave Moore play port
T5's
30mm pwk clone's
Vf3's
Milled head
Lightened flywheel
Current jetting:
152 main
52 pilot
Needle middle clip
He has ran through all of the wiring, tested all electrical components, checked every ground wire, swapped cdi's, swapped carbs, sync'd carbs, gapped spark plugs, gapped the pickup coil, new reeds, new air filters, swapped coil packs, anything you can think of. He says his mechanic's have tried every jetting combination possible but it doesn't get rid of that horrible bog, hesitation, whatever you want to call it. It's like the bike has no power at all!
Any suggestions or thoughts?
