Well incase anyone encounters this problem in the future. What I THINK it was, its a mixture of different Octanes in the Fuel. I mixed 91 and 87 together, talked to my uncle(Raced in the Knee Draggers Circuit for 8 years) and now is a automotive mechanic, he said it could just be the octanes combusting at different rates, causing wierd RPMs, So I basically just rode like that till I had to switch to reserve, and then put just 87 in, havent had a problem the last 3 days, I think it was just that (: Im hoping haha
