Starter doesnt seem to be cranking the engine fast enough?
I have a 04 yfz450. My problem is that the starter doesnít seem to be turning the engine fast enough to start.
Its a new battery (that tested good), a new starter, the valves are shimmed to .125-.150 on the intake and .203 on the exhaust, the connections are clean and secure without any short or drain on the battery.
My main concern right now is either the auto decompression system or possible a bad new starter.
The decomp seems to be working properly. However, once there is pressure on the decomp pin, it is difficult to move the arm thatís on the sprocket. Once I put enough pressure on the arm, it gives off a "click" sound and will move freely. When there isnít any pressure on the pin (like if the cam was removed) the whole decomp system will move freely. Is this normal?
Any other possible thoughts? Iím out of ideas on what to check next...
