What causes these things to break so often?

[clutchcargo]

I just think it's a bad design and there's too much stress where the reverse kickstart gear is. I am very careful when I kick mine now. Also, when the Tri-z came out, Yamaha never really had any time to work out the bugs from the 85 and 86 years. Maybe they would have fixed the problem in 87 if 3-wheelers weren't banned.

ive found that if your bolts are loose or your missing some in the kickstart area they WILL break!

[Mosh]

when you kick the tri-z,it is always best to rotate the kicker down about 3 inches.if you try to kick the crap out of it from the top of the stroke,i think it puts too much pressure,on the side case.i have snapped a few kickers already,but no case.but mine was welded up real well and i think it made it stronger.also if the kicker gears are worn and letting the kicker shaft go cock-eyed,that can cuase them to break the side cover too.i say,dont kick the livin crap out of them and you will be fine.

[Bryan Raffa]

now if we could do something about the kickstart levers from breakin on high compression motors that would be a plus!

trx 250x kicker.way way stronger than any z kicker

Does it bolt right on?

[Bryan Raffa]

yes but it needs a little grinding to miss the case

I think I agree that the welded cases are stronger. After mine broke, we welded it up and it never failed again.
Another thing I did to combat breaking one was to ziptie a small piece of rubber hose to the footpeg. When you kick those things a full stroke the kicker smacks the pegs sending some nasty harmonics up the kicker. This trick completely eliminates that.
