SR Timing chain

[kylaris]

According to the FSM, the IN cam should be @ 10 and EX cam @ 12.
then match the mating mark to the chain.
I don't have the mating mark on the chain for EX.
It wasn't there when I opened it, so I followed the http://www.frsport.com/_t_35.html and counted 10 chain links.
and what you know, there is a lot of slack on the timing chain.

Is the chain streched about 2 links? don't think that was possible.
Should I rotate the IN cam and EX cam apart to get the chain to tension?




thanks,
