Help can't get cam chain back on

<< < (2/4) > >>

Johnwebley:
took me about an hour to realise that,

and when I fitted it it was 180 degrees out of crank,

luckily it was before and after a vacation,so when I returned,I sorted it before I turned the motor

WPF81S:
Yes very silly being able to fit a cam sprocket in 2 positions

mickwinf:
surely you can't get it 180 degrees out as long as crank is in correct position and cam notch lines up it cant be wrong?

 the problem was,I had lined the crank at TDC 1-4 ,and the cam notch at 3pm ish !!

but ,spent about an hour struggling to fit chain to sprocket,to shaft,during that time the crank got moved,mugs of tea
nearly got thrown across the garage,this at 9pm friday night,the day before going off on holiday,

it finally fitted,everything rotated as it should,no rockers fitted yet,

BUT !!

 while I was away,I gave it some thought,and decided to check the timing when I got back,
sure enough,it was well out,but,I remembered how to fit it quickly,so job done,properly
timed
and all back together,
only other assemble hassle is the airbox-cargs etc

dont want to either again in an hurry

Put cam box back on and turned over engine by kickstart and am getting a load click see http://www.youtube.com/watch?v=NMbgar0vHqY&feature=youtu.be
