Yesterday, my bike started bogging pretty bad when I'd crack the throttle open, a problem that I hadn't experienced before. I pulled the carb, cleaned it and blew out alot of the jet ports, and I did the Taffy Mod while I was in there. Before I pulled the carb off, I looked at the timing of the accelerator pump squirt, and it seemed like a good 3-4 seconds. I took the AP diaphram out and cleaned it and put that collar on the AP plunger rod, and now there is no squirt at all, even with the Taffy mod collar pulled off. The AP diaphram looked ok, a bit of rust on the top, but the diaphram itself looked good. Any ideas?
