Broken Chain

[ModKat]

So, I was riding over the weekend and just dicking around going slow when I decided to get on the throttle a bit and do a wheelie when all of a sudden I squeezed the throttle and heard this loud grinding/breakage noise from my sled. I immedietly stopped and opened my hood to find my outter chaincase half blown to bits and my chain laying in my bellie pan. I was just dumbfounded by this because when it blew I was going slow and just starting to get on the throttle so, I was wondering what could of caused my chain to break when I was barely beating on my sled? Any suggestions as to what lead to this. I've seen chains break but, not under these conditions.

i wonder if the chain was loose to begin with? Was there enough slack to double over on itself, do you think??

I don't think the chain would have been loose, I was just in the chiancase earlier this year when I replaced my track and when I reassembled everything I made sure everything was set back to manufacturer specs.

If you put enough throttle to it to do a wheelie, it's enough to break a chain with a weak link. I've taken apart chains that did not seem too bad and found pins half worn through!

Hyvo

That is how and when most chains get broken! Now would be a good time to upgrade to hyvo chain and sprockets....

i have had the chain break once. too much power and not keeping the chain tensioner just right made it happen. i think carving circles doesnt help much either
