I'll probably install a Crampbuster, but lighter springs would help too, so less tension or the same? TIA. :thumbup:

I don't remember them being different.

There are at least two different springs for the H2 , early 16006-012

Hmm, going by the early PN shows this was also the 69-76 H1/KH500 spring as well. I'll dig out my H1 springs and try to do a comparison. Thanks.

I am running (3) H1 28mm return springs on the 34mm carbs.

I did this due to the effort on the 34's.

Modifying the throttle tube for quick response I really needed them.

27% lighter springs and 10% quicker throttle gives net 17% lighter twist.
:D
