So I'm a little confused. The guy i bought the bike from said the piston needed to be at TDC when you kick start it and that the kick indicator showed you when the piston was at TDC. When I'm trying to adjust my valves, the manual tells me to put it at TDC by lining up the T on the flywheel w/ the timing mark on the crank case. When I do this, I do not see the kick indicator showing. Then, I'm thinking, Wouldn't you want the piston to be at the bottom of the stroke to create the compression when you kick it? What's goin on here!?!?  |

Hi there I'm Dave from Dunsborough WA ( I dont think its the same WA though ?) I'll try to ease your confusion though ? The little window shows you your inlet valve cam , approximately TDC or going through it . ( the valve is opening getting ready for piston going down to suck in fuel mixture) . Then compression happens (piston comming up) , fires ( just before TDC ) Piston goes down to bottom (then exhaust valve opens) piston coming up , then go back to the beginning TDC . So you only see the window indicator every second time around TDC thats why you use the marks on the flywheel because the indicator is only a guide ! I hope this helps & I hope my explanation isnt too smartarsey cheers from Dave .

Hi, The kick indicator is set up for ease of starting...the engine starts best once you have taken it a little past TDC on the compression stroke, so around there somewhere the indicator shows itself. The timing marks as Dave alluded to are there purely for maintenance such as timing the engine's ignition system and for setting up the valve clearances during adjustment etc. There are also other marks on the engine for setting up the cam timing and these are internal in the engine... Hope that helps... SR |
