I am new owner of a 1993 Beta Trials bike and trying to figure out some things on it. Previous owner didn't know much about it and never even added gas - he was just flipping the bike. I'm not even sure what model bike it is - it shows Tipo B6 and OL9401 on the tag, no headlight, white rear fender, orange front fender and around a 250cc according to the seller. I found the 1991 manual online that one shows a 2% fuel mixture - which I assume to mean 50:1? But, most of these forums say to run 70 or 80:1, with a higher octane fuel (around 100 octane if I can get it). Most of those threads are referring to newer bikes. If I'm using Lucas Semi-synthetic 2 stroke oil (since I have it) what are your recommendations on the mix?
I also need to change the engine oil. Looks like I can run a 10w30 according to the 1991 manual. Regular, semi-synthetic, synthetic?
Any other advice would be appreciated - things to look out for, what tire pressures your running, etc.
Thanks in advance for the help. Excited to go try this out - I've always wanted one.
