This could be caused by a few things… check in the following order. -You might be at TDC on the exhaust stroke instead of the compression stroke - Check the engine case/ cam sprocket markings are aligned perfectly - Your valve timing (cam chain/ cam chain tensioning) might be off - Your valve clearance may be significantly off.
250cc Clearances are different. Intake: 0.05mm-0.1mm Exhaust: 0.08mm-0.13 All other processes seem the same. manualslib.com/manual/2327177/Yamaha-Ybr250-2007.html?page=64#manual
Hi doomdog 308, As far as I'm aware, the process will be the same with carb models and after a quick google search it seems the clearance specifications are the same as well. 0.08 - 0.12mm Intake 0.1 - 0.14mm Exhaust Hope it helps!
Hey there, I haven't tested it on GPS unfortunately no. Since I took the old exhaust off and replaced it with the Lextek CP1 system I've gotten it up to 60 on the speedo, but it's much more comfortable cruising at around 50 - 55mph. I'll post up a top speed video.

Hi can you tell me if the valve clearance is the same for carb and fuel injection model's.
My intake valve doesn't move when in top dead center
