    I’m going to check the spark plugs tomorrow but what I did notice today when I was checking a few things was the spark plug boot was barely making contact with the wire on number 2. I snipped a little off the ends of all the wires and reinstalled the boots to make sure they were making good contact. I didn’t have a chance to run the bike as it was a little late and I did not want to bother the neighbors too much. Will definitely let you folks know tomorrow. Hopefully that was the issue

      Hello everyone

      Just wanted to post some information on the progress of the bike. I went back to the stock 15 pilot jet but kept the 130 main because I don’t have a smaller main. When I get a chance I’ll put a 120 main and see how the bike runs. The biggest improvement is putting b6es spark plugs instead of the recommended b8es. The bike has been running fairly well. Only issue I’ve noticed is when I’m cruising over 80km it hesitates a little, it doesn’t want to run smooth. If I twist the throttle all the way then the bikes comes alive and runs smooth. It’s at about 50-75% throttle that the bike runs a little rough. I haven’t been messing around with it too much because it’s so much fun for city riding not so much for highway riding yet.

      Any idea why this may be? Would doing a carb sync help with the issue or should I play around with the fuel screw and air screws?

      Thanks again!

        The pilot screws only affect idle and off idle.
        If it idles well, don't change them
        They should be 1 turn out on fuel and about 2 turns out on air

          Would those setting be suitable for pod filters and a 4-1 exhaust?

            For pod filters you should fit air correctors, Leave ALL other settings, needle position and pilot jet STOCK and just increase the main from 95 to 110 as a starting point ( you should end up around 102/105 )
            Pods should be quality free flowing K&N, S&B, APE, Unifilter etc and not cheap chinese or no name items which are generally more restrictive than the stock air box or mask the pilot jet and main air jet air bleeds.
