Well after working on my 200x for almost 13 years I’ve finally got it to run and drive but... only on choke I’m pretty sure the carburetor is ok but I noticed that when it is running on choke I can feel air blowing out the intake on the frame and the choke butterfly whenever I rev it up will go crazy. It’s 100% in time I’ve checked it like 3 times it does it with or without the carburetor on the engine. So I pulled it and lo and behold a bent intake valve was discovered! It’s like a micro bend just enough for you not to see light coming through but enough for air to escape. Any good brands of valves? Should I just go ahead and replace both of them? Do a port and polish job while I have the head off? Bigger valves? Let me know what I need to do. I’ve never done valve jobs before. The specs on the engine is: wiseco 10.25 compression piston and everything else is stock. I have a complete exhaust that I want to put on but the header is too short to reach the second half of the exhaust. I don’t know what brand it is but it’s old nothing brand new I’m pretty sure it’s a dg exhaust but I don’t know.
