Hey guys, need some advice. Its hard to start my bike, have to pull or run start it to get it running. Took it to a mechanic (I just relocated and don't know how trustworthy the guy is but he seemed nice) who told me the valves are the issue and they cannot be adjusted any further. I've rebuilt plenty of 2 stokes in my time but really have tackled a 4 stroke engine rebuild. My question is, if its a valve job I think I have the tools and ability (from this site) to do it but how do I know if its the head and shims that are the issue. Or, do I bite the bullet and try to find a Honda mechanic to do it, or if the head/valves and so forth have to be replaced should I just look for a good used engine on ebay? thanks in advance for your comments.
