old wr200 yamaha

[bruceMember]

my son bought a wr 200 the other day and i was wondering if anyone out there knows what the fuel mixture ratio is suposed to be . the local yamaha stealer { dealer } reckons 30 :1 but seems to oil the plug quickly , using a b8 plug mineral 2 stroke oil. if anyone has a clue i would be greatful as it would keep the boy off my back about buying a new one
:laugh:
cheers bruce townsville

Hi bruce, scott here mate, I ride a wr200 and i mix my fuel 30mls to 1 litre, 95 premium. and i use ngk plugs br9es, for when your racing or doing fast long trails. but if your just riding round slower trails in lower gears, its best to use br8es. it burns the oil better n u shouldnt fowl as many plugs.when riding tell your son to pull the clutch in and give it blast with the throttle, to clear its throat if it feels like its chokeing up. cheers, scott from crescent head, N.S.W.
ps… use semi synthetic oil,not full synthetic.

Hey Bruce, I would have been inclined to run it at 32:1 and run a BR8ES plug. If it is oiling the plug you may want to lean it off a bit on the carby. Fiddle with needle position would be the first thing to have a go at.

Another thing to keep in mind with the wr 200s are the power valve, is to make sure you keep them kleen because they do fowl up can make the bike run like crap.Bigger Al stuarts point.

Manual says 24:1 yamalube. I have run 32:1 fully synth for ages on mine. I’m sure you would be able to run higher oil ratios than that if had to but jetting will probably be affected a little. Maybe.
Manual also says BR9ES but I cannot run that plug on mine. Too cold, keeps fouling. A BR8ES is more reliable.
