Ok guys. I performed a little maintenance on the max and installed new plugs, COPS, and a shotgun procedure. My max ran fine before the work. After initial startup idle was fine. All was good until the ride to work. After about 2 miles the popping began. Nursed it home after work "discouraged." Tore into it a couple of days later and preformed the shotgun procedure. Idled up the road. Road a little and then ran it through the gears and low and behold the popping came back. I did get a little of sediment t out of one carb when I drained the bowls. I checked the inside of the tank and it is shinny and clean. I and going to drain the bowls one more time and shotgun again... Any suggestions???
More than once I've gone on a service call, where a problem like this developed after changing plugs. It's easy to crack the porcelain while swapping plugs. Especially if you use a long automotive socket. My own bike, when this happens, I look back at what I just did. The socket in the factory tool bag is perfect to get them loose, and tighten them. A piece of hose is best for taking them out and starting them in. You'll never cross thread a plug this way. If your problem persist, it may be the case. Or it may not be. Running fine BEFORE is a tip off. I hope it's fixed and running fine. A Vmax doesn't start too bad on 3 cylinders.
