    Broken Kickstart shaft

    Anyone ever sheer off their kick starter shaft ?

    We're not talking about stripping the tynes off.. I mean busting the shaft right in half.





    I did that Sunday on the YZF. When hot I usually don't use the decompression release, just kick.... Well, you guessed it... SNAP


    Any idea why something like this happens ?

    snapped

    Thats sucks man... Hope you werent stranded or anything... anyhow, I use the decompression all the time in the drill, the compression is feirce, i almost brke my shin making the mistake of kickstarting with a nike on, i still have a popeye sized bump on the shin... anyhow, I know the shafts are somewhat over $100, your manual may show you how to install them. ......
    I know the 98 yz400's were snapping for people were trying to start them like a 2 stroke. I'm sure you will prob use the compression lever more often now...That just sucks... I read on another forum of someone rigging up a YZ125 or 250 starter on their bike for they were about 5'9" as well.. good luck and keep the post going with update if you dont mind..

    if you tried to slap at the lever like a 2-stroke that would explain it. You should always use the compression release on the YZF or risk the consequences. The fourstroke staritng technique can be a real learning experience

    I take blame for this one...

    Ya... I have a tendency when the engine is hot to not use the compression release when starting the bike. I weigh 200 lbs and rarely have a tough time kicking it over. I assumed the shaft could handle the torque... my mistake.

    We were a good 20 min from the trucks and there were 2 horrible river crossings I had to navigate through before I could load the bike up. After about 10 tries I managed to bump start it then road home scared to death I would stall at the bottom of a hill in a mud bog. Fortunately I made it home without stalling.

    I'll certainly use the relase from now on.

    The shaft is $120 and I'll have the shop do the install. Shouldn't take more than an hour.

    This bike has sure given me a lot of opportunities to build character.:think

    I know it's too late now, but we always tell our first time four stroke racers if they're kicking the bike so hard it's leaving a mark on the kicker where it's hitting the footpeg, they're not doing it right.

    I've seen bikes with less than 20 hours on them that have a 1/4" indent in the kicker where it's slamming into the footpeg. Man, something's gotta give!

    Thanks DualSportr...

    That's good advice.... I'll start kicking a little gentler from now on.... Using the CR lever, saying my prayers and eating my vitamins :D

    Damn... whoda thunk... so many things to master before you even hit the trail....

    CR Lever...

    How does that work?
    Is it using the stock knuckle?
    Does it come down on the foot peg better than the stock lever?

    Thanks,
    - Sean

    Ooops.... we got cross wired there...

    CR lever = Compression Release lever

    Sorry if it sounded like Honda CR KickStart lever....

    Just trying to cut down on the typing..... instead I had to type this .... So much for shortcuts :D

    Holy moley!

    I was reading this post and went out to look at the kickstarter on my 3 month old yz250f -- huge gash halfway through the shaft! I alway use the compression release. This thing is going to break sometime in the futrue for sure. Any alternatives to the $120 stock lever? Any way to repair this before it breaks?

    any solutions

    Now is it your actual kickstart shaft, where the peice hits the foot peg, for they have placed additional metal there to compensate this.....I did the same in the beginning, i lost half the metal on the added lip on the kickstarter. When I replaced my bars and grips, I took one of my old grips, cut out a portion and placed it on the rear of the foot peg where the kick starter hits, i used 2-3 zip ties and adhered it to "cushion the impact" of the kickstarter to the peg. Now granted, this shouldnt be necessary, but in my mind it is preempative maintenance.... I thought I had my routine down pat, no problems for a long time, then yesterday at the track, started bike up, then popped off choke for prob 30 secs, rode into a muddy berm, and stall.. I tried all my tested routines and it just wouldnt grab, went up an pull started it real quick behind a 4 wheeler for it was hot and i didnt want to screw around with it... I am now thinking that if the bike is not properly warmed up, and stalls, the bike cant figure out if it is in hot start mode or chok3. it is really weird, for no gas given to flood it out.. oh well.. maybe the grip on the foot peg might work for you...
