Hi i just got my APE cct today and i was reading up on a couple threads on how to install it. Some threads say that its just a r&r but another thread said that you need to move you pistons to TDC before removing the stock cct. Some extra info can help before i start anything thanx!

 

I switched mine out also, and no, you don't need to have it at TDC. Put the bike in neutral and don't move it while you install it & you'll be OK.
One thing I did to adjust the tension on it was to install it on, then screw in the adjuster until you feel resistance with moderate finger pressure. Start the engine and continue to apply very slight turning pressure to the adjuster. You will notice that it will creep inward (tighter) as the engine turns. Eventually it will reach a point that it won't want to go in anymore (again, with little turning pressure); that'll be your sweet spot. It took me a couple of tries to get it right.
Have fun, and remember; patience is a virtue, lol...
