Here is a bit of info for you T7 owners. I will build on it as i do more. Spring rates. I have calculated these. They are very close to what a tuner would offer up. Each range will give plenty of scope. If you are a big luggage carrier, or planning to jump triples!!, the high end of each range would be fine. Each will get a good rider sag. Static sag gets some air time, but i am not as concerned with static, as i don't care much how a bike handles when i'm not on it. These are base on stock installed preloads for each end. Forks, 13mm no adjustment. Shock, 14mm, +10mm of adjustment. You get 0.4mm of additional preload per click. I have installed a set if hicalibre brand fork springs in a T7, they are 5mm shorter than stock, 418mm vs 423mm stock. This is fine, still get 8mm of installed preload. More than adequate. Shim it if concerned. Same bike, installed a Eibach shock spring. It is only 225mm long, compared to the stock 240mm. There is a spacer used to make the gap up. It gives 10mm of installed preload vs stock if 14mm. In any case, if you use a long spring, you will need less adjuster preload on shock. As for forks, I would go back one rate. Ktech quote they're springs in N/mm. This is the correct way. But for continuity, i have converted they're numbers to kg/mm. Accepted ideal rider sag, Forks, 53 to 63mm, 25 to 30% Shock, 60 to 66mm, 30 to 33%. Static sag if you like, 10 to 30mm. Don't sweat it if it just out side these figures. It will have minimal difference. We're not pro MX riders!!! Forks, Stock, 0.57kg/mm. 70 to 80kg, 0.57 to 0.60kg/mm 80 to 90 , 0.60 to 0.65 90 to 100, 0.64 to 0.67 100 to 110, 0.66 to 0.69 110 to 120, 0.68 to 0.71. Fork spring options. Ktech, 0.61 to 0.70kg rates. 425mm long. Hicalibre, 0.55 to 0.65kg rates. 420mm quoted. I measured 418mm. Race Tech, not sure as yet. Shock, Stock. 6.95kg/mm. 70 to 80 kg, 6.95 to 8.3kg/mm 80 to 90, 8.4 to 8.7 90 to 100, 8.8 to 9.1 100 to 110, 9.2 to 9.5 110 to 120, 9.6 to 9.9. Shock spring options. Ktech, 7.6 to 9.7kg, 245mm long. Hicalibre, 7.5 to 9kg, 242mm long. Eibach, various rated, 225mm. Needs a spacer. Rally Raid, 8.2 to 9.7kg, 235mm long. Straight up fit. Good option. Only 10mm of installed preload. Race Tech, 5524 spring, 7.1 to 9.6kg. 240mm long. There are lighter rates than 7.1, but not worth noting. The owner of this T7 weighs around 105kg geared up. His bike has crash bars and a bash plate. Set up with about half a tank. Springs used, 0.65 in forks and 9kg Eibach on shock. With 8mm preload on forks, rider sag comes in at 59mm. Rear sag, remembering this shock spring only has 10mm installed preload,(vs 14mm stock), plus 5mm from adjuster, comes in 56mm. 28% sag front and rear. Will take a couple clicks out of preload on shock, will settle near 60mm. If using the above spring rate guide, can certainly go down a weight range with out any ill effects. Will still get plenty adequate rider sag. Weight distribution. As best as i could weigh this rocket, this what i got. Unladen, 48/52. With rider, 44/56. The rider weight split is 36/64 when seated. Valving. Here are stock shim stacks. Comp and rebound use 6mm ID shims. Forks, Comp, 16x0.10,(5) 12x0.10 16x0.10 14x0.10 12x0.15 10x0.15 Rebound, 16x0.10,(5) 10x0.10 16x0.10, 14x0.10 12x0.10 10x0.10 8x0.10 Shock, 12mm ID shims. Comp, 34x0.15, (9) 32x0.15 30x0.15 28x0.15 26x0.15 24x0.15 22x0.15 16x0.70. Rebound, 30x0.20, (8) 28x0.20 26x0.20 24x0.20 22x0.20 20x0.20 16x0.70. The shock comp adjuster is like a high speed comp adjuster. It uses a preloaded spring and check plate to control flow through adjuster. The oil being controlled is only oil displaced by the shock shaft as it enters the shock body. This equals only 15ml of oil total. As for other damping adjusters, they will work most effectively in first third of adjustment range starting from hard. Not to say there is no effect past that range, it just won't be as noticable or effective. After a bit of testing, the owner of this T7 is pretty happy with new valving and springs. Rider weight, ready to roll, 105kg. Forks. 0.65kg springs. Comp, Started at 6 clicks from hard, ended up at 9. Good compliance, can handle a reasonable jump. Still a heavy bike to jump. My focus was more on alround performance. 17x0.15,(4) 16x0.10 10x0.10 16x0.10 14x0.10 12x0.10 9x0.30 Rebound. Started at 10 from hard, finished at 8. 17x0.15,(4) 9x0.10 16 12 9x0.30 Edit, I have fitted a midvalve shim arrangement into this T7 Rebound unchanged. Base valve stack, 17x0.15,(2) 17x0.10 14x0.10 12x0.10 9x0.30 Midvalve. Float, 0.35mm. 17x0.10 15x0.10 14x0.10 12x0.10 10x0.10 Midvalve use 8mm ID shims Shock. 9kg spring. Gas pressure 180psi. Was surprised how little it needed to get it better. Comp. Adjuster started at 9 from hard. Seems ok. 34x0.15, (9) 32x0.15 30x0.15 28x0.15 26x0.15 24x0.15 22x0.15 20x0.30,(2). The only changed shim. This is called the clamp shim. Arguably most important shim in stack. It controls overall stiffness of stack. This is all i found it needed. Will continue to test to make sure. Rebound. Started at 17 from hard. Still working on where it needs to be. But will only be a few clicks either way. 30x0.20, (8) 28x0.20 26x0.20 24x0.20 22x0.20 20x0.20 18x0.30, (2). Only shim changed. Read above comment. Edit. I put this shock back to stock valving when i modded forks for midvalve. This is the first shock i have encountered that spring can be swapped and valving can cope. Recap, 9kg spring. Refer above for stock shock valving. Valving options. I have put together sracks that require minimal shim changes. Are they perfect? No. But in 99.99% of cases, these stacks will be plenty adequate and provide a very good ride. Forks. Fork stacks all based on 5wt oil 70 to 90kg. Stock 0.57 to 0.60kg springs. These do cover a broad range.For comp, If wanting firmer rider, add a 17x0.15 shim. Softer, take out a 17x0.15 shim. Rebound. Adjuster, start at 8 clicks from hard. 6 to 10 is about where it will be. 17x0.15, (3) 10x0.10 16x0.10 12x0.10 9x0.30 Comp, Adjuster, start at 9 clicks from hard. 6 to 12 is usable range. 17x0.15,(3) 10x0.10 16x0.10 14x0.10 12x0.15 10x0.15 90 to 110kg option. Rebound, based on 0.64 to 0.67 springs. Adjuster, start at 8 clicks from hard. 6 to 10 is about where it will be. 17x0.15, (4) 10x0.10 16x0.10 12x0.10 9x0.30 Comp, Adjuster, start at 9 clicks from hard. 6 to 12 is usable range. if wanting a bit firmer, add 1 to 2 of the 17x0.10 shims, softer, take out the 17x0.10 shim. if wanting much softer, leave 17x0.10 in place, and remove a 17x0.15 shim. 17x0.15,(3) 17x0.10 10x0.10 16x0.10 14x0.10 12x0.15 10x0.15 110kg plus. Rebound, based on 0.70 springs. Adjuster, start at 8 clicks from hard. 6 to 10 is about where it will be. 17x0.15, (4) 10x0.10 16x0.10 12x0.10 9x0.30 Comp, Adjuster, start at 9 clicks from hard. 6 to 12 is usable range. if wanting a bit firmer, add 1 to 2 of the 17x0.10 shims OR a another 17x0.15 shim. Softer, take out the 17x0.10 shim. if wanting much softer, leave 17x0.10 in place, and remove a 17x0.15 shim. 17x0.15,(3) 17x0.10,(2) 10x0.10 16x0.10 14x0.10 12x0.15 10x0.15 Shock valving options. Gas pressure for all, 180psi. Oil, these stacks are based on Motul 2.5wt oil. CSt 16.1@40c, 6.2@100c. Maxima 3wt is very close. When choosing shock oil a viscosity index, VI over 300 is important. Shocks work pretty hard, less than 300 and oil will degrade pretty quick. Here is some info, not mine, on shock and fork oils. http://www.peterverdone.com/wiki/index.php?title=Suspension_Fluid Stock shock valving, with stock spring is good for the 70 to 80kg rider range. Doesn't appear to need any work. If your in thus range, and want shock firmer, only need to change out clamp shim. Stock is 16x0.70, go up to a 17x0.30,(2). Start comp clicker at 8 from hard. 34x0.15, (9) 32x0.15 30x0.15 28x0.15 26x0.15 24x0.15 22x0.15 17x0.30,(2), new. Rebound is fine with stock spring. 80 to 90kg. based on 8 to 8.5kg spring. Started at 114 from hard. Still working on where it needs to be. But will only be a few clicks either way. Rebound, 30x0.20, (8) 28x0.20 26x0.20 24x0.20 22x0.20 20x0.20 17x0.30,(2), new. Comp, Start at 9 clicks from hard. Adjust to taste 34x0.15, (9) 32x0.15 30x0.15 28x0.15 26x0.15 24x0.15 22x0.15 20x0.15, new. 17x0.30,(2), new. 90 to 110kg and 110kg plus Use 9kg spring in the 90 to 110kg range, 9.5kg in 110kg plus. Comp. Adjuster started at 9 from hard, adjust to taste. 34x0.15, (9) 32x0.15 30x0.15 28x0.15 26x0.15 24x0.15 22x0.15 20x0.30,(2) new. Rebound. based on 9kg spring. Could use 9.5kg without issues. Started at 14 from hard. Still working on where it needs to be. But will only be a few clicks either way. 30x0.20, (8) 28x0.20 26x0.20 24x0.20 22x0.20 20x0.20 18x0.30,(2) new. Fork oil level. Measured with springs out, 85mm from top, forks collapsed. New springs use thicker wire, will displace a little more oil. As springs only are partially submerged, 90 to 95mm oil level would be fine. Miscellaneous stuff. I have fitted a schrade type bladder cap from a YZ85 shock. Direct fit. This will be a works in progress. Will update as i get more info. It won't be as detaled as Africa twin data base, i don't think that is needed. With Eibach spring and spacer. Rebound adjuster on shock should be facing this side. Needs to be turned 180 in this pic.
