So I was plundering deep into the show a few weeks ago and I found what looked like a old can of paint. When I cleaned I off it was a really old can of two stroke oil from some brand ive never heard of before. I was itching to try it, and I ran some of it through my 250. Dude... The premix back then smells so much different than it does today. It reminds me of the stuff I use in my chainsaw. Whats so much different about the oil they used back in the 70s as opposed to the I use now? I cant imagie how great it was with that as the only thing you could smell at the track... Kind of a side note... what do you guys think the best smelling premix is? I know its a opinion but it has to be either klots or yamalube. I Just wana hear what you all have to say!
