fixing up a arctic cat 2010 550 atv
 

I bought a new ATV, but I decided to keep this old AC and put some time and money into and see how much more km's I can get from it.

Its got a few issues, but the first thing I am going to try to tackle is the valve adjustment. The click pretty bad, but the bike runs fine. It doesn't back fire or miss fire, but I think the valves need to be adjusted just based on how loud they are.

I don't have the repair manual for the bike, but whats the process and specs for the valve adjustment?

Should be able to download a service manual from,<mymowerparts.com> or maybe <CountryCat.com> for the specs. I'd bet that you can find a youtube video. Do you have the owners manual? Specs should be in there as well. I have a 400 and a 700, but I'm sure the 550 is slightly different. mymowerparts/K&T Parts House has a service manual for 2010, almost all models, btw.
