An exhaust leak at this point in the System can be the cause of several performance issues. Depending on how big the leak and if it's one or both cylinders, it can cause RPM changes at Cruise Engine RPM ( little load) or while Accelerating, Misfiring/ Power Loss/etc. ( under more load). At Idle it may not even be detectable! (again, depending on how big the leak and if both cylinders).
I recall several times on the Purple Board, guys going nuts trying to fix mysterious symptoms,... Repeated Adjusting/Tearing into the Carbs and Fuel System/Pump, etc.......... spending loads of time on the Ignition/Electrical System checks,......only to find it was Loose/Leaking Header Pipe Gaskets.
Being SO easy to check,...It's now my FIRST item on my trouble-shooting list for these symptoms such as pio142 reports.
With countless hours looking through past posts of similar issues I already came across that header bushing being an issue and looked them over already.. they were already tight and had no visible or audible leaks. plus I don't think they've ever been removed considering this bike only has 7000 miles and it being fully stock.
But when I get a chance I'll look them over again while it's running and report back.
