Freestyle Xscream 865 Reminder to change wrist-pin bearings every 50 hours!!

[dcptr]

Just got this motor 5 weeks ago, total about 80-100 hours on it. Just got told 2 days ago I should change the small end bearings coz they tend to 'go' sometimes.
Today she poped after I tried starting it up.
Who can give me my options for repairs? Is it do-able?
5 weeks, only been 3 days I havent been out riding.

Ouch! That looks terrible. I shudder to think what the rest looks like.

Can the billet cylinder be welded back up? Same with the case? Or is my new motor s bin job? Jokes aside thanks.

X-Scream would be the best place to start. Regardless of whatever opinions we have on here, they will ultimately be the best to answer your questions and will know exactly what options you will have.

Was the motor brand new 5 weeks ago? 100hrs of Riding in 5 weeks?

Sorry that this happened, but this thread convinced me to replace my wrist pin bearings... now.

Omg... That must be some ty aluminum to just bust open like that...

I blew a rod last season, I though i was pissed about killing my 735cc.. hopefully xmetal can fix it up for you man.

X2, ScottS has replaced his 3 times in 2 seasons. Every time he has opened up his engine, he has seen evidence of them failing and so replaced them. I don't put a fraction of the hours on my engine as him so I haven't cracked a bolt on mine yet but threads like this really make we think that I should.

Do you guys think this is caused by the larger pistons?

 

[Kawastyler]

Hallo, please let me know if you like to sell you engine......

 

[chriselmore_1]

Maybe xmetal got a bad batch of billet. Because there's no reason a stock stroke motor should bust through the cylinder like that... The base is pretty thick... In don't get it

 

[suva]

Why don't they use cageless bearings like in skidoo sled motors?

 

[Lucaumpits]

bro, that dont look good you lucky if you can save the cylinder,

There are few things going on at once here. First-- parts fail.. Its just a matter of when. The more power that is extracted out of an engine the shorter its life span. Second-- when buying a high performance engine, you have to maintain it and keep an eye on the condition of the parts much more closely than you would with a stocker. Cageless bearings are a pain in the *** and watercraft don't run the rpm to make it worth while. RUST can still happen and one little spec on any bearing will casuse such catastrophies. Even a billit cylinder is not strong enough when you do the math of the forces going on inside of it. Finally, there is no one to blame. If a hundred hours were gotten out of this engine then that would have been a good time to check it out at the very least. Its just a case of a part reached its life expectency before being replaced and this is what can happen.

Please tell me you are kidding with a comment like that ???? I makes no difference whose billet cylinder it is or what batch of billet it came from, let alone how thick the base of the cylinder is as it is still no match for a broken rod that turns into an unguided projectile. And for reference I am almost positive that area is thin due to the port layout.
