I had another thread, but decided to start this-anyways, I have a friends old bike- a 98 RMX 250. Low end it seems to bog down , mid range seems fine, and top end seems great. It spits out oil out of the pipe all over the back fender everytime I ride it. I thought it might just be from him not riding it for a while, but this is the 3rd time I rode it this week for about an hr each. Any ideas? The mix is 40:1 according to him, I havent used any new fuel yet.
