A65 valve springs

[EDDIE SIMPSON]

i recently bought some hepolite valve springs. they did fit the cups but the coils diameter is thicker. the problem with that is there is a chance of coil bound at high speed. a clearance check is in order when assembled.

The ones I bought last year don't fit very well at all. Ones I've bought historically have been fine.

Hi,
My springs have just arrived and they fit nicely in the bottom cups.
The springs lengths are roughly to the pre '68 spec but with 5 coils of approx. 3.75mm wire and 2.75 wire respectively.

do these have the green (or green and white, can't remember which) paint on them Dave?

Hi Allan,

No paint a tall.  The last set did have green. These new ones are pretty much the same the earlier spec.

Hi,

Having had a reply from SRM, I am re-assured that the springs are of top quality and the same as are used in staff bikes and SRM engine rebuilds.
I will be fitting them after the head has been in the dishwasher for a final clean and when my nasal cavity and sinuses stop over producing virus packed mucus.
