Melted piston rings, gotta love it *PICS*

[JLJunkieMX107 10+ year member]

So my friend bought a Honda CR250 dirtbike. He tells me the wal-mart 2 stroke pre-mix for weed eaters will work in his bike. I said naw man you need to go to the bike shop and get some Motul 800 or Amsoil, something high quality if you want the bike to last. He didnt listen. We went to the track a couple weeks ago and going down the straight his motor locks up. We just tore the bike down last night and look what we found. . . . . . .

The top of the piston has a shit load of dings from the rod bearing flying around

Huge grooves in the side. It melted the ring into the piston

Another shot

And it even cracked the shield

tell him to take care of his bike if he wants it to take care of him... i allways used mix oil from the yahmaha dealer on my bored 30 over blaster... still wish i would have never sold that...

Yeah I tried to tell him its not the same stuff. He got what he deserved because he didnt listen. We are sending the motor off to FMF to get a job done on it. Should be badass when its done.

it's times like this, where the only thing a good friend can do is rub it in his face. as often as possible. preferably with many other people present.

no that's what friends are for. if i gave my buddy a hard time for doing something stupid, and be basically told me to fuck off and never talk to him again, he wasn't really a friend in the first place //content.invisioncic.com/y282845/emoticons/imo.gif.3a57bcc70a4835dc53e86ffae1a0b041.gif

hmm we seem to differ in opinion then. to me, a true friend lets you put it in his ***. if he doesnt, then i dont consider him to be a true friend. i know im a good friend...

different strokes for different folks i guess.

tell your buddy that I'll sell him my RM250 and it comes w/ oil and a topend kit that isn't needed just extra.

sounds like he should stick to 4 strokes though

lol thats what i was thinking. how rod bearing pieces get past the rings, and into the cylinder head is beyond me.

 

[JLJunkieMX107 10+ year member]

Dude you should see the cyclinder. The rod bearing scraped the **** out of it. I would take pics but its already been packed up to send to FMF.

Naw the 250 uses 2 rings. The motor is getting redone by FMF and we are putting all Wiseco in it, rod, crank, piston etc.

and its not really an easy fix when the cylinder has huge gouges in it.
