Some notes about the valve adjustment..
You can remove the side plastics and then unbolt the tank and simply slide it backwards and out of your way.
I found it hard to find TDC as the mark is a fairly small vertical line. To be safe, i removed the spark plug and turned the crank until the piston was at the top of the cylinder and then cross-referenced that with the TDC line on the crank.
Once i did that i could slightly wiggle the rocker arms and knew i had it.
You will need to unbolt the horn mechanism and also unhook the 2 pair valve lines for in order to access the front valve.
Remove the valve caps with a 15/16" open end wrench
Loosen the locknuts from each valve stem.. mine were on super tight
Loosen the valve stem to allow access to your feeler guage
I used a deck screw with a wire cap in order to tighten the valve stem down onto the feeler guage.. thanks @JerryHawk, read that in an old post of yours
Since i wanted to have them set at .004/.004, i tightened down on a .005 feeler guage and then locked the nut.. this allowed a .004 to gently slide in with slight rubbing but would not allow the .005 again, which is what you want
I put everything back together and started her up, sounds nice and healthy and now i have a little leeway as they may tighten back up a bit between now and when i do again at 500mi

Hello, thanks for all your updates and info you put out.
I have the X-pro titan 250cc dirt bike and i'm sure my valves need to be adjusted and I would like to do so.
Did you have to remove the engine out of the frame to adjust the valves? Im new to riding and this is my first bike... everything is kinda overwhelming.
