I bought 2 older yamaha's, one is an 86 and the other is an 87, they are both the exact same but one has a different engine code and I was told one was 80cc and one was 85cc. Problem is that I can not find any atv made back then that would have came with an 85cc engine. I believe they are little badgers and they only came with 80cc I think. Engine codes on them are 800cm3 and 850cm3, not sure if that will help anybody but if you can explain this nonsense to me I would appreciate it because I need to buy a few parts for them.
