Guys it's the dead of winter here and I dug the bike out today. Going to drop off the wheels this week for powder coating and need to decide what to do with the engine. I have the complete bottom end rebuild kit here (thanks again Matt @ Tyga!) and don't have a problem doing that if it's needed. Here's why I think it *might* be, but please tell me what you think.

Below a certain rpm, the bike almost feels like it has a dead cylinder or maybe in fact it actually does. Once it passes a certain point while revving up, it catches the other cylinder (or something happens???) and it seems to be running on full power. Does this sound like a bad seal in the bottom end? If it's a carb, pv, or electrical issue I'd obviously rather leave the engine alone and rebuild it later after a thorough thrashing during this season's track days. I tend to agree with Fontyyy on this one due to the parts availability, cost, and time issues for me.

Yes I have a good working set of carbs on the SP and am just waiting for someone to tell me to yank them and give it a try.
