Thanks for the advice. What was your issue and what exactly should I look for? I did not change lifters and valve springs as planned while in Colorado. Weather was too good and I rode. Back in Michigan now and Bike is in shop getting new rear tire and a tuner. Previous owner put Python pipes on and no tuner. Lots of popping on decel. Shop will Dyno Bike with tuner and I will have a base to compare in spring when I will have it on the dyno again. Over winter I will change lifters, valve springs, install Andrews cam and new cam bearings, rocker lockers and anything else I might figure to be a good idea. I need to see the dyno results and look at cam that is in Bike before I order a new cam. This Bike ran strong. Half way through 3rd gear pull tire broke loose and spun momentarily before catching. Happened a couple days later in 2nd gear. May have just been warm asphalt and I hit a slick spot. I’ll know more when I get it back in my shop and tear it down.
