    My buddy Jon has broken his kick start shaft for the second time. He has a hefty leg for sure but any ideas on why this is happening? Anyone else break the kick start shaft on a Husky 125? Help with your thoughts is appreciated.

    PS, He is kicking a 165 so a new kick starter from Motosportz would be appreciated.....hint....hint

    Is the spline shaft breaking or the long shaft portion of the kick lever? If it is the long shaft portion, my guess is the shaft is get chunked when it hits the foot peg. After it gets notched enough, then it breaks at that location.

    I saw Kelly break one... Seems like mine is getting loosey goosey....

    Yes, we NEED a longer, stronger option for the 165

    Matt,

    His spline shaft is breaking right at the case where there is a machined indent.

    I wore out a kick start lever on my '02, but this is the first shaft I remember hearing about breaking.

    Wow, he has a serious kicking leg!

    Since the shaft is free to rotate, I can only guess that he is also putting some lateral load as he kicks the lever. For example, instead of kicking straight backwards, he is kicking slightly on an angle away from the bike. This would put some bending load onto the shaft.

    I think you are probably right. He was also experiencing problems with the kick starter not engaging and kicking against no resistance which would make that worse when the lever impacts the peg and he puts a side torque on the shaft.

    I broke my 2008 CR125 kicker last weekend. It was the lever, around where the boss inserts into it. Cracked in half. Replacing it is expensive for me, since I decided to replace the whole kick assembly as well as everything that attaches to it (read: ordered a new 2012 WR 125!)

    A longer kick starter would be a huge plus! Thank goodness my size 13s don't take much boot to fire the 165 up !:)

    Wouldn't a longer kick starter put more load on the shaft?

    never broke one and I feel hard to believe that it would happen on a 125 or a 165

    wrong technique I would say

    try to start a CR 500

    it will not break the shaft but your leg if you are unlucky

    did kick for a while a a XR 650, no thank you

    have now a CRF 450 with shitty battery, I only swear if it is not firing up after 4 kicks

    the WB 165
    its not starting with your hand as the 125 trim did but intimidating or breaking is very far from that.

    You will need to remove the clutch side case but not split the engine cases. It is also much easier if you remove the clutch to get the kick start gear out. I feel your pain.

    That's a pretty substantial shaft to be shearing off like that. My guess is bad heat treating. Either that or they are using a MIM part instead of a forging.

    bahahaha, are you kidding???
    a metal shaft shouldn't just break due to poor technique...
    if so why didn't it break 100hrs ago when the bike was brand new?
    poor metal quality by the looks of it.
    lol.
