Yeah I'm thinking that myself. I fed in the details earlier as per @mylesdw suppllied and moving the shock forward by around 100 mm and angling the shock to 90 degrees I can actually increase the spring tension to a value of 0.81 (obvious as the shock will be upright), but if I just shift it along from a centre of 475 (original) and shorten the length and then increase the shock angle to around 70 degrees from the original 47 degrees I can maintain the 0.66 figure of the standard bike which should maintain the spring rising rate. The only unknown is the Triumph spring actually feels softer than the Kwaker original so yeah a spring change may be on the cards.
If you are using a spreadsheet (such as Excel) note that the SIN function takes radians rather than degrees as its argument. so:
SIN(90) will NOT give you the sine of 90 degrees but
SIN( RADIANS(90))
will.
For the comparative stuff you are doing it may not matter (I've not checked) but if you carry on to use the numbers to specify a new spring it does matter.
