After getting all back together bike fired right up and sounded awesome. With the choke 1/2 out while warming up it idles very nice. However, while playing with the throtle in the low range around 1500 rpm I'm hearing an intermetent Pssst sound. Not like a leak but a short burst Pssst sound. I let the bike warm up then rode it about two miles. It is truly a different riding bike from idle through full throttle I'm not sensing any flat spots it's running solid throughout the power band. Got back to the garage and let it idle and it seemed to have ironed out any problems. Let the bike sit for a couple hours and restated. Fired right up idles fine but, still getting the Pssst sound occasionally. Rechecked all connections everything seems A OK. Any ideas guys?
