Kr1 1989 misfire issue
Posted: Sat May 15, 2021 12:15 pm
Hi so my issue is the bike will be completely fine low end revs then high end if you light bring the revs up to high revs it will also be fine but under load full throttle at around 7k it will begin to splutter/misfire then when you let off it will drop to 1 cylinder then fire back up once the revs have dropped and it’s not under as much load. I have tried changing plugs, tried 3 other coils, wiring looks okay, spark plug caps look okay and carbs were cleaned not to long ago but I have a carb rebuild kit so I’ll fit that and possibly look at the reeds. If anyone has an idea on this I would much appreciate the help thank you
