Hi everyone, this is my first post here. What I have is a 99 recon 250 and the valves are a little noisy. Can anyone tell me what the clearances should be? And also, is there any way to adjust the clutches on this bike? The biggest issue is the valves, I dont want to run it too much until they are adjusted properly. Ohh, one other thing, is there a chain in the motor that turns the cam that has to be adjusted also? I just purchased this bike on a spur of the moment thing and its my first honda. Other than these few questions, it seems to be a solid quad. Ohh, if it matters, it is a manual shift also. Thanks.
