do anyone have a problem with there 900rr fowling plugs.... i have a 98 rr and it fowls plugs way to often.... any suggestions

 

What type of fouling do you have? Oil, carbon, antifreeze? Those are the usual suspects. If it's oil and they foul often then you got oil rings going bad. Antifreeze = head gasket about to blow completely out or head bolts backed out. Carbon = too rich somewhere in the rev band. While it's best to have carbon fouling (too rich) that's often the hardest to correct. A dynotune with a sniffer is sometimes needed.

 

thanks... it is like a carbon build up... thanks for the help

 

check the choke operation to be fully open. i don't have the problem. do you use a k&n, maybe too much oil. are the plugs uniform in color/fowling. how many miles on them before you remove and see fowling.

I agree that a overly oiled air filter is just as bad as a dirty airfilter; requiring the carbs to work harder...imagine drinking a fresh thick milkshake and you cannot get it thru the straw...now after it melts it is easier...like a excessively oiled air filter and a properly oiled air filter..get it?? or the choke could cause the same symptoms

 

thanks for the advice... it is usually only one plug at a time that goes.... i changed them at 10:00 one morning and by 2 or 3 one had already gone...
