I just bought a 1984 suzuki rm 250, this is my first 2 stroke, what mixture should I use?

HTE RM'S ARE GREAT BIKES CHECK WITH A DEALER, I THINK THEY WILL TELL YOU TO USE A SYNTHETIC OIL BUT THE MIX IS 32-1

HI MATE THESE ARE SOME LITTLE TIPS 1ST BUY SOME 2 STROKE OIL I RECOMMEND {SILKOLENE COMP 2 PREMIX} 2ND BUY A 2 STROKE MIXING BOTTLE ON EBAY 1 LITRE WHICH HAS A RATIO OF 40:1 THEN WHEN YOU GET THIS MIXING BOTTLE YOU FILL IT TILL IT TILL THE PETROL REACHES 1 LITRE LINE THEN YOU FILL THE REST WITH 2 STROKE UNTIL IT REACHES THE 40:1 LINE THEN PUT THE LID ON AND GIVE A SHAKE THEN PUT IT IN THE TANK ALSO ITS A GOOD THING YOU CHANGE THE GEARBOX OIL EVERY 4-6 RIDES BY WARMING THE BIKE FOR 2 MINS THEN UNDOING THE PLUG UNDERNEITH THE ENGINE THEN PUT THE PLUG BACK IN WHEN DRAINED AND REFILL WITH {SILKOLENE LIGHT GEAR OIL} PUT 750ML OF THIS IN AND THATS IT ALSO WHY I DO RECCOMEND IS CEANING THE AIR FILTER EVERY 2 RIDES IF ITS A DIRTY DUSTY ATMOSHERE JUST TAKE THE FILTER OUT AND DUNK IS A BOWL OF PETROL AND THEN DUNK IT IN SOME {SILKOLENE FOAM FILTER OIL} THIS STUFF IS VERY STICKY AND IS REPELENT TO WATER AND STOPS DUST GETTING THROUGH THE FILTER AND THEN AFTER 3 MONTHS REPLACE THE AIRFILTER WITH A NEW ONE SO 3 THINGS YOU NEED 1:SILKOLENE COMP 2 PREMIX 2:SILKOLENE LIGHT GEAR OIL AND 3:SILKOLENE FOAM FILTER OIL SILKOLENE IS A VERY GOOD SPECIALIST IN OILS AND ADDITIVES THE TOP RACERS USE IT ETC GOOD LUCK BUD

The correct mixture is 20;1. and as you have probably already heard.. smoke is better that a knock. run it thick. also.. 40-60 weight is the call for the tranny. i use 80 wqeight. straight 80.
