    wiseco crank problem

    well got the motor back apart and looking at the gear on the crank the spacing of the teeth on the wiseco crank is in the shape of a "V" very tightly spaced which would not allow the cam chain to seat down onto the teeth. The Stock Crank teeth are in the shape of a "U" spaced much wider than the teeth on the wiseco which does allow the cam chain to seat completely down onto the gear. Needless to say the wiseco crank has been returned and OEM parts have been ordered .
  2. I recently had my entire motor rebuilt on my 2009 yz450 installed all wiseco parts and as he was getting ready to time the motor he realized the cam chain will not seat itself down on to the crank gear its almost as if the gear is wrong. when you install the cams the cam chain is so tight that the tensioner does not do anything. I called wiseco and they want me to have the motor torn back down so i can return it to their engineering department for inspection. anybody ever have this problem or seen of this? this is my first time using wiseco cranks and so far i feel as if i should have bought something else

    metallic noise

    the original springs that were in there were the stock kyb springs and they were replaced with race-tech springs

    metallic noise

    yup thats exactly the sound im talking about....they were real quiet with stock springs...then changed everything and now its kind of noisy
  8. just rebuilt the forks on my 09 yz450 and replaced the springs, along with the free piston mod where you drill the holes to make the piston more reliable. after getting the forks all back together and compressing them they make almost of a metallic noise while compressing but function perfect any ideas?

    race-tech vs mx-tech spring calculator

    how exactly would i measure the front forks for their sag numbers?

    race-tech vs mx-tech spring calculator

    yeah i know...race tech at 145 pounds (without gear) recommends .45 front springs with a 5.15 rear...mx-tech at 155 pounds (with gear) recommends a .42 front spring with a 5.1 rear spring a big difference in the front
  15. I have a 2009 YZ450 that im going to be replacing the springs and rebuilding the forks. I weigh 145lbs....the springs in the bike are stock. the fronts are .47 stock and the rear is 5.5. Which spring calculator is more accurate? they are both showing complete different spring rates for the front and are close on the back.....so what springs would you suggest?
