Question about 1999 Yamaha YZF-R1
Check your fuel filter, sounds like starving when certain amount of fuel required. Have seen debris collect in tank at shut off screen, if you have one where line attaches to tank. BUT, sounds like a fuel limitation issue....Anyone??

Tachs are coil sensing. Since you have a start problem, chk tach wiring at coil and coil wires.
If all is good, Locate or identify the tach wire and disconnect it. The tach wire should be on the negative side of the coil. If bike starts without tach wire hooked up, Your tack is more than likely the culprit. If bike stll won't run, chk for power to the coil and any possible fuse in ignition circuit. Under the seat I think. Good Luck

if its valve chatter you will hear it just under the valve cover pretty pronounced, but usually valve chatter gets quieter as the bike warms up, you might look into your cam chain adjuster those get loud and chatty at higher rpms.
