Heya there, hope this is the right forum for this post. Basically I've noticed I'm losing oil slowly but surely, and after looking over my Yamaha FZX250 (Zeal) I noticed a small crack down where the oil bolt on the underside of the motor is. It looks like the bolt was overtightened and has split the metal its set into. Anyway I've loosened it in the hopes that it won't split further, BUT what can I do to fix this??? I;ve only had my bike a short time, and it was in pretty terrible condition from the last owner, and was just about to get the paint fixed up and the forks refinished. Is there anything I can do to fix the damage thats causing the leak, or how would I get it fixed, I don't have much bike knowledge yet, so this looks like it could cost me $$$$. Should I just take it to get looked at?
