I’ve messed with other carbs before (PWK’s) and imho, the stock carbs are much better. If you’re looking for enhanced performance others like the Mikuni VM34’s. My stock BS38’s run great.Alright fellas followed 5twins direction on cam chain adjustment, and adjusted my valves which were all off either too tight or too loose and I still can’t get this thing dialed in. How junky are the carbs from mikesxs or tcbros? At this point I would take a bike that runs pretty good over barely runs. I’m starting to loose my patience with this bikes resilience and my lack of success. I’m at a total loss as to what to check and or adjust at this point.
