    You were right, this gonna be the most expensive and interesting bike rebuild yet, it's really smashed like crazy... wonder if the previous owner got all bones intact,hope so.

    Noise you are hearing in the front is an exhaust leak somewhere in the headers. New exhaust headers will fix the issue. Besides that, the engine sounds good. Forks will have to be run on a dial gauge to see if its straight.

    The forks you can roll them on a flat table and usually you can tell if they're bent or straight. As far as the noise in the front of the motor check your cam chain tensioner or your valve Kawasakis are known for the cam chain tensioners. Mr motorcycle in Dallas Texas has a lot of parts they also ship world wide pretty fair prices on parts .

    To check the forks, disassemble and suspend the stanchions and outers between some V blocks. Use a DTI to check for run out. If you cant do this or aren't confident, strip them down and take them to a machine shop. They will be able to check for straightness.
    that ticking noise is likely just blow by on one of the munched joints on the extractors

    they are safe and in spec. Front forks failing would be bad..... Huge respect to
    ya' for taking on a (re)build like that. Very much looking forward to how the final

    for the front fork you can test it after mounting the front wheel itself and before tightening the 6 head 2 bolt you should spin the tire see if it has curve, Look it from the up site it helps better look.
    then gave it a pressure by pressing on your ignition. if it goes 3/4 good to go. Sorry about my bad English :P

  • @SaqibKhaliq
    @SaqibKhaliq Год назад

    Hey. Amazing video, this build is mega. In terms of the forks, you can look down them by eye and see if they are bent easily. Another check you can do is to back off the preload, and damping.. then compress the fork with body weight and see if it feels okay. My recommendation - send them off to a pro to be rebuilt, with new fork oil and seals. They’ll flag if anything is damaged, and also you could even get upgraded internals if you feel inclined. Best of luck!!

    • @CJMediaOfficial
      @CJMediaOfficial  Год назад +1

      Thank you for the information Saqib! Only negative with sending them off is time, I just hope if I go that route it won't take a month or two. But that is a great idea especially since they are an important component

    Not sure if this has already been answered, but if you want to know if the forks are straight you can measure the distance between bottom of the forks where the axle sits, then turn the forks a quarter turn (one fork clockwise and the other counter) within the triple tree and measure again. Do that a 4 times. If the forks are bent then the measurements will be off. Not sure if that made sense lol.

    Ticking Sound coming from the front is likely an exhaust leak from the small hole in the right hand side header. They often sound like ticking. It is unlikely to have valve lash out of spec at only 8k miles.

    Fork check- pull the shock bodys use a straight edge in 4 places around the lengrh of the body to check to straight. For the tripple clamp you would need the manufactures specs on it to check the degree( i would just replace the triple clamo if the shock bodys are straight)
