timing marks?????

right iv just checked the valve clearences on the old girl, took it all apart and went to set tdc on the rear cylinder and couldnt get the dots on both cams to line up with the head????? so i set at tdc with wire down the plug hole and the two cam lobes facing in and clearences were fine dont understand cos the front cylinder was easy,all marks lined up with the head and lobes were facing away from eachother witch is fine?????
i had an issue sort of like this when i used to ride motox i raced a kxf250 four stroke for a year then checked the shims and when i took the head off the marks looked like the exhaust cam was 1 tooth out (but the bike was running perfect)????? did the shims and put it back together LINING THE MARKS UP and the fooker wouldnt run so took it apart again and set it 1 tooth out and it run great!!!!!! found out the problem was that the sprocket on the end of the cam is only pressed on so somewhere throughout the year it had spun on the end (so the cam was in the correct possition for the timing but the sprocket with the marks on was out)
IS THIS FEASABLE ON THE SD
any oppinions are welcome

but its still producing 118bhp at the rear wheel on the dyno ????? if it was a tooth out would it still run that well

What yrs the bike? I did my shims a few months back on a 07 (57). all the write ups I have seen said rear and front line up in the opposite direction to each other. mine didn't. both front and rear marks lined up facing out. like this .\ \ / /.

I take it once you checked the rear adjustment, then put it all back together unlocked and rotated the block locked it to check front? both marks don't line up togther. you need to work on each sepratly. do the work on rear or front reasemble then the other.

the gears of the SD are solid one peace and stamped with the timing mark. so no the marks can't more.

took the lids of both cylinders lined the front marks up no worries checked the clearenses no probs then turned the crank withe the 14mm allen key on left side of engine to try lining up the rear and just could not get them lined up at all so i set it tdc manualy by wire down the spark plug hole and got the lobes sort of facing slightly inwards (facing eachother) like it said in the workshop manual but the timing marks are out??????

Just carried out my 30k km service on my 06 and checked the valves, tolerances were good but found difficulty in lining up the marks (or actually finding them on one cam)on the rear cyl and ended up just using a screwdriver down the plug hole. Anyway you look at it, it was not as the manual stated.

If it is 05 sd then the exhaust cam mark on rear cylinder is almost invisible - this mark stays behind camshaft bridge:

This picture shows the mark without cam bridge:
