Hi< I bought a 1969 Commando with a 1973 850 engine. It has a single 36mm mikuni with K/N filter. I immediately had to replace the intake boot because of cracking . I now have problems with my right spark plug fouling black in a matter of 10 minutes riding and eventually it stops firing. I have been through two plugs to confirm this. Also I put replaced the fuel lines and drained the tank to make sure no crap got in the carb. It also has a inline filter. I am not very knowledgeable about the mikuni and need some advice. Thanks
