Top single springs.
These are the ones I stretched, though I had to change out the front one for a spare as it was a little deformed on the business end.
Might help, can't hurt I don't think.
I also got some VN 1500 Timing chain adjusters,I'm thinking of shimming them out and fitting them. A 10 mm shim will still allow them to penetrate 9 mm deeper than stock, and have the advantage of their trick double locking system.
I have attached a picture of the two ACCT side by side, the 1500 models have a secondary locking mechanism, that uses the principles, of a Chinese finger stall.
The primary locking system uses a spring loaded pall, that meshes on the fine jaws machined into the tensioning shaft. Looks real stout to me.
