In desperate need of some knowledge. 2011 Stryker running great. I’m a long time rider but not very handy. Installed new cobra swept pipes. Starts up, sounds great in first gear. Second gear however, bike loses power and stalls. I know I know, running lean and I need a flash. But I was under the impression that with a stock air intake this bike could handle a simple exhaust swap. Was I wrong? Do I need a flash as well? Or did I mess something else up like not changing out the original O2 censor? Thanks in advance.
