04 450 chassis 500AC
i got the motor from astroman, and the kid rode the bike 5 times....now there is a good rattle... piston? wrist pin or rod bearing? we havent even looked but the kid says maybe he just wants a 250 and some dough ... this bike scared him a bit (he is throttle happy) SO
2004 CRF450R clean title, with a 90 CR500 motor all fabrication is done, FMF pipe and silencer, everything else is stock.. the motor just needs love. it isnt locked up, but we havent looked at it so i won't speculate as to how bad it is... he did limp it back to the truck (1/4 mile) and it ran so we don't freakin know..... anyway he is broke from the build so i doubt it'll get fixed or ridden anytime soon.... bike is in bakersfield, he wants to trade for an 02 or newer CR250R plus a little bit o cash or looking to get 3500 delivered halfway in socal for the bike AS IS. a good bike to buy if you are one of those guys who wants to go through everything yourself and have it all fresh or for someone who has their own motor all ready to bolt in and keep this one for a spare after repairing it ( or fix it and sell it on eby for $$$)....email me for specific pics of the conversion or with REASONABLE OFFERS/TRADES. Thanks for looking, Sean

interesting. i bet the piston came apart and the crank shoved it through the bottom. more than likely a cast piston . i have hard time believing you busted that rod, but it could happen i guess. if you did infact limp it back to your truck as you claim, that throws the broken rod theory out the window though

of course it was the cast piston that let go . plus he said he limped it back to the truck. the motor would of died instanly with a busted rod. it would however still beable to run to some degree with a broken piston. ill guess it had the famous intake skirt crack and had been rode for a long time that way, eventualy the skirt busted, but still allowed the motor to operate long enough to return to a pickup. chachi243, im not trying place blame on why, where, or how this happened, or whos fault it is. im only pointing out what i think has happened, so dont take it the wrong way.
no offense taken
yeah you guys are on it... im sure it was the piston skirt too, but as far as anyone saying cast is the reason, ive had much worse luck with forged pistons as far as failure rate, not necessarily broken skirts but ring and heat issues... this obviously is due to either a blown out of round bore or something that would cause the piston to fail early (astroman says the motor had an original bore but he put a fresh piston in it when he built it)... either way i am not holding him responsible as a used motor is a used motor, i know anyone takes a chance and how could he have known it was close to letting go.... either way, if all that crap went around the bottom end, then the rod bearing and crank will still need attention, besides the bore and possibly the head if it was a wrist pin bearing issue....as far as the case, iv'e welded worse but there is already some JB around the drain plug so its like putting another bandaid on a pretty used up case half.... i just know they are out of bread and the kid wants to pimp his truck..... i suppose a new bore, and top end, and then maybe rod bearings on the crank and crank bearings in the case and seals.... should be an easy fix but they are over it... any interested parties contact me with contact info and i'll pass it on to the dad so they can make up their minds...

i didnt hear the final word on what truely happened? did the piston skirt bust and got kicked into the bottom? the best i can tell from the photo only the left half is broke- doubtful the crank took much damage as it pretty hard steel. left side case i think is only $267- maybe cheaper from SH. if the damage isnt too severe you might be better off fixing it and selling as a good running complete bike. just my .02
