Hi;
I am building a fast road engine (1310, AC RS Cam, Stage One, Mildly Modified Head).
I don't want to spend extra on a Vernier Duplex Setup but "think" I need a Duplex Chain as they stretch less after fitting and Gear Setup to replace the standard one in this Metro A+ 1275 (Circa 1989). To set it up I was going to use a standard woodruff key and then work out what degree offset key I needed.
The problem is that there are so many gear and chains about I need some help picking the correct one.
