I have changed the plug lots of times because the old regulater rectafier would just melt the electrodes so i started changing them every month, i premix the bike with the petrol.
Right my TS 50 has a 75cc big bore kit with full big one race exhaust system and racing carbon reeds and bigger jets. After the bike was run in it was fine and very fast for a 50. But over the last few months the bike bogs out as if it's not getting fuel once it's warmed up. I really need to diagnose what's wrong with this because it's my daily transport. Thank You for any help anyone cam give me.
