hey guys, I just came across a 85 Beta TR33 and I need some help. The guy I bought it from new very little about the bike and said it had just been sitting for a few years. My dad and I put in some new gas and she fired right up. We rode it around for a while and put her up. Does any one know what the gas mixture is supposed to be? I have heard anywhere from 40:1 to 100:1 on various forums. This is my first trials bike and I am not really doing much with it now besides trying to find my balance points. Thanks guys! the bike: My dad rockin it!
