dkortje said:1. The service manual says TDC is when "I" mark on rotor is aligned with pointer. Is this the "I" after the "H" or is this the punch mark on the rotor?
2. Once you have TDC, how do you know which direction to place cams, ie. since a four stroke has two complete revolutions for each spark, how do you know if the punch on the cams should be "out" or "in" for the particular part of the cycle :eek:
If you look at the cams from the left side of the engine the exhaust cam should be pointed at about the 10 o'clock position and the intake cam should be at about 2 o'clock.
dkortje said:Rich, doesn't the timing mark rotate twice for each cam rotation,
dkortje said:, is when you set the piston at TDC, how do you know if the cams should be installed at position 'out' or 180 degrees 'in', ie. how do you know which TDC in the timing cycle you are at?
Brilliant Biglou, it took me forever to get them out with my slippery fingers, and the needle nose seemed too rough :eek: . Now how can I get all you guys and galls to just do my mechanic work for me :laugh: !!!biglou said:My favorite tool for bucket & shim removal/instalation is the magnet on a stick. Keeps things where they should be. :thumb:
Aha!!! :clue: :clue: :clue:High Lord Gomer said:I was very worried about how the engine would know if it was at TDC at the end of the compression stroke or at the end of the exhaust stroke. I finally called EGorr and he told me it didn't matter as the bikes fired on every revolution....both the compression and the exhaust strokes!
