setting valve timing ktm450 sxf 09??

Recommended Posts


was riding my bike last week and landed off a jump and lost power.

no bad sounds or any smoke just very underpowered!! pulled off track and stoped engine to check (as you do) OIL WATER PETROL ECT.

nothing, after taking it to the local shop, hes seems to think the valve timing is out somehow. when trying to start the bike flames and the od backfire happens??

need to check the timing , any ideas as no marks.

For setting the timing you are supposed to use the factory alignment tool, really though if the flats on the cam are up and parrell at TDC it's in time (use a straight edge)


If your cam gears may have spun on the cam it may have been do to a lack of oil perssure. make sure you check your pressure relief spring it needs to be 38.5mm. if not it needs replaced/shimmed
