I bought my brother's 91' KDX200 from him.havent rode it yet because the rear hub is broken but should get that fixed soon.
I wanted to know what oil ratio to use in the gas.I'm new to 2-strokes coming off of a XR100 any info would help. thanks
I use a synthetic or synthetic blend like Golden Spectro at 40:1. I have not had any problems and have had better than average life of rings and components. I would point out that the manufacturer calls for 32:1. The only problem that I see regarding too much oil is fouling of the kips and spark plug. This will also tend to lean your mixture out a little as well. My $.02
