Usually you find it with a timing wheel and dial indicator. Also TDC is different for each cylinder.

'06 K1200R- in pieces
'73 Honda CB500F- slow but fun.
'77 Yamaha XS 750 triple- kinda

I can't find it. I changed timming chain using engine locking tool, but i would like to be sure that timming is set properly. Marks on the top of engine (timming shafts) are ok, but how can I check that the bottom (crankshaft) is ok?

I changed timming chain, sprockets and rails because infamous "vibrating noise at 3000 rpm" make me nervous every time i ride my bike. The interesting thing is that the new rails are different than original. After assembly new timming chain, sprockets and rails without mounted chain tensioner timmg chain is very tense. Is tight to the point that i had a problem to mount timming shaft sprocket.

regards

I found it. TDC mark on crankshaft is in the hole below the sprocket (You have to use flashlight to see it)

locking tool part #

Have not been here in awhile...
in process of replacing timing chain and sprockets, need to lock the engine to loosen crankshaft sprocket.
Two questions, one the part number of the locking tool and two, torque setting of the crank bolt. My CD-Rom and dying drive is giving me fits today. The picture of the timing mark was not viewable to me as well

When I tried to loosen the bolt out earlier, the chain jumped backwards a few teeth. Moment of panic

Thanks Kendrick,
Got the tool Tuesday and have the new parts installed, just not torqued the crank sprocket yet.
The tightness of the new chain is remarkable compared to the worn one. Helen wants her bike back NOW!
