Anyone use a Rollmaster timing chain?

I have. They are a good chain....the bottom sprocket has a lot of degree choices which is nice. The only negative is I have found the bottom sprocket to be a bit tighter than it should (ID). It goes on hard and comes off hard....you need a very good puller to get it off. It's really too tight...I'd consider honing the bore a little to make it fit 'properly'.
Heat the crank gear, leave it in the sun.
I agree, its tight, I beat mine on. Lol
