Question about 2002 Honda CR 125 R
Hello assuming there were no carburetor jet changes and your bike is running to rich. or you have realy dirty air cleaner.
Fouling plugs due to to much oil could be the wetside oil seal needs replace because it is letting your trans oil enter the crancase or you have worn crankshaft roller bearings.

Wot type of 2 stroke oil do you use ? only use race spec type 2 stroke oil as your engine is race tuned and needs respect ! also when was the last time you replaced the piston and rings , stripped the carb and cleaned it ? your only supposed to use them for 4 to 5 races max then strip and clean and check for wear or damage including the crank bearings and seals etc ! there not like a road bike ! if you dont use it for races and just have fun then you must still ride it as if racing ie short bursts then corners etc etc , and not thrashing it long distances as if on a road because it will melt the piston or damage the crank bearings ! only use NGK race plugs also , dont use too much oil mix ratio either as this can damage things as well ! I've raced mx 2 stroke for over 30 yrs and had these problems when i started and lernt from friends and the experts i chatted with ! Hope this helps ! P...
