"If you cut a spring you increase the spring rate and decrease maximum travel before coil bind" Had to think about that. 1st thought, how does a cut change anything??? No its the shorter length that changes things "If you stack 2 springs you decrease the spring rate and increase travel" You are saying here in effect the spring length varies the rate? Not sure about that. "If you nest 2 springs you increase the spring rate (add the 2 rates together), travel is limited to whichever one has the least" Or the amount of travel available in the forks? Triumph springs are soft. Yam springs support a similar weight with a lot less travel so most likely a little stiffer. So nest them on both legs and get double the carry capacity. ( give or take) Nest them on one leg and get a 50% gain. I would hate to disappoint Buck. OK then random facts and figures. Triumph tiger forks (1996). Bike weighs 209kg dry so 235kg? wet? 5mm dia. 45 coils @ 545mm long = 225 solid +320 space so the 215mm (actual) travel fits easy. XS650 spring (I have 4). Bike weighed 225kg wet. (heavy slug) 4mm Dia 63 coils @ 393mm long = 252 solid +141 space ( stock Yam had 130mm fork travel according to Clymer) Right so then for some creativity. If I cut 2 springs down and add them (stack) so as to have one and a half or so then I can utilize 664mm or even 678mm if I go up into the fork caps. The Yam springs go right through the Triumph spring spacers giving more length. @ 664mm we get 105 coils making 420mm solid spring and 244mm space for travel....ample. Trick is to keep the Yam springs from clashing with the Triumph ones. More so because they are stacked and the cut will throw them off line a bit. If I did I would relieve the 25mm or so of preload, maybe give it 10mm as a token to stop rattle etc. So. Add springs to 1 leg? Add springs to both? Buy new maybe not quite heavy enough springs and slap em in? Can be done of course but is it worth it? Ok I need to eat and get back to the Western list (gunnado) while Y'all thunk on it.
