You don't have to worry about that if you are SURE you mix is correct at 32:1. I run Castrol Power 1 fully synthetic at a 25:1. I just like to keep the motor lube properly, it hardly smokes. I have make some of my own testing over the years, up to ratios of 20:1 ALL of the motors ran more reliable (engine wear) from getting a bit more oil. A lot will differ from what I said, but this was the truth. A Graham Bell tested a YZ125 an RM 125 on a dyno to show that the 20:1 and 25:1 even makes at 9000rpm up to 1.5 HP more compare to the 40:1 50:1 mixtures and had showed much less ring wear and crank bearing's wear than the other mixtures. There is a myth that some say the less oil in your mixture the more power, this is true till a certain point, but you can always jet a bit for the richer oil mix. Like I said, I have tested this myself and runs XC with my bike and the wear is down compared to the other ratios I have run in the past. I don't say change your ratio, thats just my experience and some big engine builders. I know a lot will disagree and say its because of other problems, but I know what I know, the only bad thing about rich oil mixtures, if its not a synthetic oil, it is always a bit wet at the end of the exhausts when riding at low RPMs, but with what I do and the oil I am running, no problems at all... I thought a share this with you guys...
