Race Fuel, two stroke oil and premix ratio
Posted: Sat Feb 28, 2015 6:53 pm
Anyone with experience of racing these bikes will have good knowledge on this subject so which way to go ?
I have previously ran yam ypvs race bikes and TZ350 and always used castrol 747 oil at a 40:1 mix ratio. With both the TZ and the YPVS I ran a 50/50 mix of Avgas and premium unleaded but I know the avgas argument depends on the squish volumes and compression ratio being used but I would like to hear experienced two stoke racer's/engine tuner's opinions on this please ?
