  1. I am sure that Rick would give your money back,but, he is an engineer and has his own ability to rate springs. I know for a fact that he checks everything. I would trust him completely. He is an honorable man. Kerry
  2. I didnt want to hijack this thread. I just want some feedback. I advertise on TT and want to meet people who will talk to me. I use 17-7 sst because of it's ability to withstand high heat without lossing load. The extra cost of the sst may not be cost effective. Maybe I'm trying to fix something that aint broke. KC

  4. Hey guys, I make my clutch springs out of 17-7 stainless steel. I make the spring the stock rate or lighter and make it longer for more load. I have found that chrome silicon(which is the wire of choice for high performance) will take a set at 300degrees. A used set of stock springs from a KX250F were 2mm shorter than new ones. If you are interested or think I am full of it,let me know. Kerry cannonracecraft.com
  5. The 450 springs are .47 rate and the 250 springs are .45 rate. Both are 43x510 series. I feel the .47's will work with no revalve. KC www.cannonracecraft.com
  6. When we were testing the 05 yzf's we found that the stock springs took a set when taken to 11" of travel. We assumed that all 05 yamahas were alike. At first we were making them at 465mm. Then 467mm. Now we offer both 467mm and 472mm. We also make the ics springs in two different lengths. Kerry
  7. Yesterday we installed a 110cc Long Shin w/4speed in my xr70. I paid 1000.00 for the 70, 325.00 w/shipping for the 110 on ebay and CannonRaceCraft springs are 89.95 each end. This bike is faster than my ttr125 up to xr's top end which is now 50mph+. My ttr is not stock. Kerry
  8. 98xr250 is correct. Spring rate is controled by 3 things. Wire size, diameter of spring, and active coils. Load is a function of travel. Kerry
  9. On your 1995 XR 250; for the fork springs the part number (RT) for 1995 is Eibach 999 which is 34 x 432 (dims) and the other more recent years list RT part #3444 which is 34.90 x 444. From our research 1995 seems to be a crossover year for determining spring dimensions. Cannon Racecraft has some 34443's in a .44 rate available. As for the rear, stock was a 9.3. RT sold an Eibach 887 which is 61 x 55.5 x 219, but the actual stock spring was 59.3 x 53.2 x 221 (?). We can make you a shock spring in whatever rate you want. Call us 405-524-7223.
  10. Hey Greg, On that DR650, feel free to give us a call for after market springs. Cannon RaceCraft at 405-524-7223, we can make to them the length and rate you want.
  11. Lew is right on. We use a collar to connect the two springs. I make a dual rate setup for the xr50 using this technique. I have thought about trying it on a big bike as I have a 29" inseam but I havent done it yet. Kerry
  12. Sean, there should be no problem getting new springs of whatever rate you desire or need. The suspension on your bike is Showa. Anyone who sells springs can get them for you. Shock Doc is in Florida and very competent. Kerry
  13. Dave, we do suspension like that for quads and sprintcars, by using a spring called a tender spring. It is very soft, often wound out of flat wire. It takes up the extra travel without affecting the primary rate. Kerry
  14. We have a pair of aftermarket .46's. KC CannonRacecraft.com
  15. Hey Doc, if you adjust the free sag, go ride, come back and have to adjust again, what is moving. Or is air building up? But where is the air coming from? KC
