H2 clutch springs

[BIG H]

I have done a simple load test on some springs.
Load given is to compress spring 5mm.
(In brackets is spring free length & wire cross section)
Original but used H2 spring 9Kg ( 31.75mm x 2.63mm)
Kawasaki 92081-1114 10Kg (33mm x 2.7mm)
EBC CSK-023 11Kg (32mm x 2.67mm)
Kawasaki 92081-1033 12Kg (33.5mm x 2.81mm) old part number was 92081-105 (from Z1/Z900)

interesting stuff

Cool! I love experiments.
How about doing a range of values and plotting them to see how they compare across their working range. Like, are they all linear, when do they begin to bind up etc.

H any chance of making some more of your fly wheel pullers but a bit longer as your h2 h1d pullers just bottom out and touch the dowel when used on a kh or e rotor cheers in advance

Ok,but it will be about a month before i can do them.
What extra length is required?
Extra thread,extra plain shank,or both?

[downpipe3]

thread length maybe 15mm I will measure and confirm

yes 15mm longer will enable it to reach the crank without bottoming out
if you make some I will have 2 off you please mate
