Message: [QUOTE="David Trustrum, post: 83918, member: 21529"] This isn’t a question, more a tip. In a lower thread I had asked for fork spring specs so I could calculate how much I needed to stiffen the springs. Course I could pop US$50 for new ones & wait for them to arrive, but 20min & free sounded like a better deal. Basically the less active coils (all the ones that aren’t touching at either end) a spring has the higher (stiffer) the spring rate. (Bend your ruler at far ends then move your hands closer & it gets harder right?). So how much to cut off? (Old spring rate x active coils)/desired spring rate. That gives me the number of coils I want left. In my case I had .3 springs & 33 active coils & I wanted .33 springs. (works with pounds as well). This = 30 coils so I cut off 3 from the original 33. (Usually the numbers aren’t this round, with rear springs be more accurate). I just used a disc grinder to lop the coils off & then GENTLY using a bit of heat from a handheld propane torch or whatever bend the cut part down to touch the lower coil & dress it up to look like it did before you cut it. The springs measured 495mm before & 440 after, so we have to make up the difference to keep the preload the same. The std spacer was 85mm so a new one 140mm was cut from a piece of 34mmID (37OD) plumbing pipe. (OK so I spent $2 so sue me!) Job done. You can stiffen Front springs, Rear springs, even clutch springs, as long as you make up a spacer to retain the preload. Just beware if you are going to lop off quite a bit -that there is still room so the spring doesn’t coil bind. [/QUOTE]
