About to throw in the towel on the EJK. Bike is making good power and great fuel economy but in stop and go traffic when the Vaq really heats up, the popping has me annoyed. My buddy was riding behind me and said he can see the spark when the exhaust pops on decel. I have pretty much decided to get a PCV and try and tune out the pop altogether. I have David Sheeks map which many have had success. Until I get the scratch together to have RacnRay tune it proper on the Dyno. Sucks because I really like the easy of use of the EJK.
