Timing chain marks??? Or marks on your cams?? On the cams you should have 2 marks on each side of your cam sprocket. They should be even with the top of your jug...

T is usually the mark on the flywheel and there's usually a mark on the cam sprocket and head to line up. you can google up a service manual too most likely.
according to my handbook 350ml when empty 300ml at oil change. As a 2nd check i used a length of wire with masking tape then measure & mark the tape 135mm insert down into the fork. hope this helps it worked for me.
before you go taking your head off check that magneto and flywheel are both okay and the key way it sits on isnt flogged out.if thats not your problem if you take the rocket cover off you will expose your timing chain now this chain is marked with a line usually which is your timing mark. the top cog your chain sits on also has a mark if you can get your piston top dead center and line both marks up while at top dead center it should be fine. hope this helps thanks ladjr2
The timing will not jump until there is considerable wear in the cam chain and tensioner, it would have been rattling severly first.
Check the timing marks anyway by finding the small timing mark on the flywheel casing and find TDC and there will be a mark on the cam(will need rocker cover removed) will line up with gasket surface or be verticle.
If it is backfiring trying to start it is often an ignition problem, maybe a shorted kill switch , or coil problem
Install balance shaft drive gear onto the left camshaft.
Install the camshaft sprockets and new bolts finger tight.
Using a vise, compress the timing chain tensioner plunger.
Install a retaining clip on the tensioner to hold plunger IN during installation.
marking timing chain
If timing chain copper links are not visible, mark 2 links on one end and 1 link on the other end to be used as timing marks.
Install right and left timing chain guides. Tighten bolts to 89 in-lbs (10 Nm).
Rotate the left camshaft until the timing mark is at the 12 o'clock position.
Rotate the right camshaft until the timing mark is at the 11 o'clock position.
Position the crankshaft using the special tool. Then remove the tool.
Crankshaft special tool positioning
Install the crankshaft sprocket with flange facing forward.
Crankshaft sprocket timing mark
Position lower end of left (inner) timing chain on the crankshaft sprocket. Align the copper (or marked) chain link with the timing mark on the outer flange of the crankshaft pulley.
NOTE: Upper half of timing chain must be below the tensioner arm dowel.
Position the left timing chain on the camshaft sprocket. The timing mark on the camshaft sprocket must be aligned between the 2 copper (or marked) chain links.
Left camshaft sprocket timing mark
Place the left timing chain tensioner arm on the dowel pin and install the timing chain tensioner and bolts. Tighten bolts to 18 ft-lbs (25 Nm).NOTE: Lower half of timing chain must be above the tensioner arm dowel.
Crankshaft sprocket timing mark
Position lower end of right (outer) timing chain on the crankshaft sprocket. Align the copper (or marked) chain link with the timing mark on the outer flange of the crankshaft pulley.
Right camshaft sprocket timing mark
Position the right timing chain on the camshaft sprocket. The timing mark on the camshaft sprocket must be aligned between the 2 copper (or marked) chain links.
Place the right timing chain tensioner arm on the dowel pin and install the timing chain tensioner and bolts. Tighten bolts to 18 ft-lbs (25 Nm).
Remove the retaining clips from the right and left timing chain tensioners.
Verify alignment of all timing marks.
Install crankshaft sensor ring on crankshaft.
Locate index mark on balance shaft and mark corresponding gear tooth with chalk.
Position balance shaft on journals.
NOTE: It may be helpful to use an inspection mirror to view the marks timing marks.
Align the chalk mark on the balance shaft with the camshaft timing mark.
Balance shaft bearing caps
Install the balance shaft bearing caps in their original locations. Follow the tightening sequence as shown in the illustration. Tighten bolts to 89 in-lbs (10 Nm).
Tighten the camshaft phaser sprocket bolts in the correct sequence using 2 steps, as follows:
Step 1-30 ft-lbs (40 Nm)
Step 2-tighten an additional90 degrees
Position the crankshaft keyway in the 11 o'clock position.
Lubricate and install all camshaft roller followers.
WARNING Engine front cover replacement procedure must be completed within 4 minutes or entire procedure must be repeated. Failure to do so may result in future leaks
there was a 11mm head bolt option on some models with a protruding head 35ft\lb used 38ft\lb new
on TDC line the exhaust cam mark EX with the gasket surface.
then count chain pins from the first one above the EX
the 35th pinshould line up with the IN mark and the gasket surface to the rear

Below is a generic diagram. If only one mark is present it points upward and in line with the crankshaft center line. If two marks are present they line up with the gasket surface of the cylinder head. The piston should be on TDC and the cam lobes should be pointing downward. Be sure the chain is on the crank sprocket, not wedged between the sprocket and the balance weights. Also be sure that the chain is taught on the front side of the engine. Any slack should be at the back side of the cylinder so the chain tensioner can work properly. Can I get a “very helpful” rating on this answer?
owww,,, was the bike running when the chain broke?? There is usually some valve to piston contact when this happens - BENT valves will NOT SEAT or SEAL!! Time to disassemble the top end!! Especially if you heard noises coming from the engine when it broke? You need to set the piston at TDC (Top Dead Center) and like the cam up with the marks on the head and cam chain gear,---- Make sure the timing marks on the flywheel are lining up..if not rotate the engine another 360 degrees until they do before starting this..You MUST CHECK THE COMPRESSION before attempting to start this engine.
There are two timing marks on the crank. One is for the front cyclinder and the other is for the rear. When you line the front cylinder mark, the front cam has two horizontal lines that line up across the top of the head. Look at the cam lobes and make sure the exhaust lobes will be the next valves to open. Turn the crank and do the same for the rear cylinder. Make sur you remove the cam chain tensioners first and leave any slack in the chain on the tensioner side when installing them around the cams.
