Trying to sort out front fork excessive travel on my 2000 ST1100 ABS/TCS/CBS. Stripped forks, and not sure if springs need replacing. Existing springs are progressive, and measure 482 mm give or take, and according to the 'haynes' book makes them ok. They look good, no cracks or signs of weakness. So my question is... is there another way of checking if springs need replacing.
There is alot mentioned about preload, but if I can get the forks to dip about 5" just by pushing down with front brake on, is preload going to do anything.? The metal spacer in R/H fork measures about 95 mm, and everything looks good having just flushed out all the muck and black oil. Anti dive all looks good.
I don't want to buy another set of springs if these ones are ok. Was planning on rebuilding forks and putting SAE 20 oil in. Any advice would be welcome
Thanks
Ian
