Just like to introduce myself. Old guy with to many bikes.Have as much fun maintaining and customizing as riding. Speaking of maintaining i joined to get info and insight on my wives 2008 ninja 250r, which of course i have to maintain. :facepalm: Anyway she rides the crap out of it including track days. It has never let her down but it is time for some TLC. Need some info on valve checking and shim replacing and cam timing. I guess what i need is a shop manual. Any info greatly appreciated!

Welcome to the site Hontri!
It's a pity I am on holidays and don't have access to my laptop otherwise I would have already sent it to you.
If no one else has responded to you by next Friday then hit me up, and I will send it through to you.

hey bud welcome to the site. What I would do is get an electronic version of the service manual. Yes. If you are
Going to get
That deep into the motor. I would def look at the valve seats and shim. Timing chain, timing chain tensioner, and timing chain guides. I would change the spark plugs with the stock plugs. No quad spark or anything. Make sure you gap them properly. Also check the coil over plugs at this time. Look for any red dis coloring on them. If you see any on them you need to replace them as well. Red marks suggest spark loss due to arc and your coils aren't allowing you spark plug full power. Also another suggestion would be to check the grease in the triple tree. Run the bike low on gas before you start the project. Run octane boost and fuel system cleaner through the bike before you start. . My suggestion is to wash the bike before you take
It apart. Then another light rinse once you remove the tank. Make sure you re lubricate everything. Motor, covers, bolts, gaskets, and all other moving parts. Dielectric grease all connectors you take apart. And make sure all your grounds battery and chassis are in good condition. Also if you wanna gain a little horsepower change the head gasket with a smaller thinner one also. Make sure the cams have oil on them before you put the bike back together it helps no to scratch them. But also inspect them before you put it back together for flat spots or signs of sheering or cracking. If so you should replace with new. Hope this finds you well
