    99 yz400f hurricane conversion

    I will look into 426 radiators.HUMMM---MORE COOLING? WHY THE HELL NOT!! as far as the tank ---IMS black tank cuz black goes with everything. I really appreciate all the help and info. I will photo capture the entire process and i am going to powder coat the frame black.
  2. does anybody know what differences there are between the tank and plastics of a 99 yz400 and a 2000-2002 yz426. i want to do a hurricane conversion but was told by one industries that their kit for the 2000-2002 yz426 would not fit my 99 because the plastics are different. I appreciate any help. thanks:ride:

    '03 450 Hurricane Conversion - Pics

    I myself would love to do the hurricane conversion but I have a 99 yz400. I contacted one industries about their kit and was told the plastics are different . I dont give up easy so I checked to see if there is a difference between the tanks of my 99 and that of a 2000-2002 426 and they are the same. so if you guys might know just what is so different about them I can come up with a plan on how to pull this off. I have never liked blue yamahas. i guess I am old school and think that a yz should be yellow. my first was a 76 yz125 when i was 11 and i will soon be 41 and still love the yamadogs.

    Pitbike Running Problem

    I need help guys. I have a little chinese honda knock off that my 7 yo son rides. problem is when he puts it under a load in 2nd or 3rd it misses real bad. I put a spark plug in it and relaced the plug wire ( it had a burnt spot from the exhaust). could it be the cdi box or the coil or both? I ruled out the carb after i took it apart and cleaned it( was not even dirty inside but i ran some cleaner thru anyhow).

    New To Yz400f

    Just got a 99 yz400f. The guy i bought it from had a hell of a time starting it but it eventually fired. The outside temp was in the low 50's. I tried to start it today without any positive results. What gives with this ? Is this normal? The guy i bought it from said they were hard to start in cold weather. Any help would be very cool.thanks
