My 09 2 cycle People 50 has the newer type exhaust with the "extra" tube. I tried to install an early style exhaust off a 04 but had trouble. Mechanically the 2 are a match but I'm having trouble tracing out the extra "plumbing" that’s connected to the factory pipe. Leaving it disconnected is causing the engine to stall and run poorly. There's a rubber hose that feeds somewhere but I'm not sure where it goes or what it's for. When you trace the routing it goes under the foot panel and then up into the steering column. I haven't been able to find any return to the carb. It just seems as if it's fed up into the column and stops. It becomes a lot of trouble to pull apart and remove and I thought some of you folks may already have a solution. I thought I'd try an easy way and just plug it but the bike would hardly run. 2nd I just left if open. The engine ran better but still was stalling and torque/pulling problems. I put the original back on and she runs good as new. I wouldn't think there'd be that much difference between the 2 mufflers that would require rejetting just to make it run. That hose has got to loop back to the engine somehow mechanically or maybe converted to an electrical signal? I can't find it. I see other members posting their intent to do the same thing. Anyone know where it goes, what it is and/or how to bypass?
Thanks,
Jeff
