yup done did it today, all good though, it was a two year old top end anyway ,just figured id let ya know!!  

Thanks for that info...Will help REAL riders what NOT to do. If you don't mind me asking, What was your Sieze of choice? No oil? Coolent, Or just lack of maintnence all together? Did you leave a note saying...I'm a azz hole and don't know how to take care of a bike, So we must just end it????? I find it a shame that YOUR still around and the bike is not.  

i guess all our preaching about preventative and proper maintenance meant nothing.
it is ALWAYS  cheaper to maintain the bikes as opposed to repairing them.
i hope somebody learns something from this.  

you guys have helped me out with my bike alot from jus readn sum stuff but for that guy to sound sorta happy is jus Dumb my bike blew up two weeks after i got it not my  falt got it lik that and i was realy sad  

well it was NOT due to lack of maintnence by any means to be honest i am not sure how it happend, 32;1 pure synthetic full antifreeze hell even fresh gear saver, not that it matters, i was just cruising not even on it and bam she locked up, i was just trying to make the best of a bad situation and you guys are no help, but when i rebuild it friday at least itll be like a brand new bike  

I dont know what everyone's problem is. I have seen bikes seize or blow out for no real good reason. Pro racers blow up a bike once in a while and they have a crew to do maintenance. Sorry to hear about the blow up by the way.  

Well, Sorry mud. I took your comments the wrong way i guess. As just being flippent and like oh well another bike in the crapper. Any way good luck on the re build and let us know what you found. YZ WOODS  

Make sure u really mix ur fuel well!! A slug of lean "oil to fuel" mix will wipe out a top end quickly. I always add the oil to the container first, then pour in the fuel and shake with a little dance number that I made up.  also todays pump fuel is for the birds. I think u'll have better luck if u give ur bike a steady diet of race fuel.  

you mean like 110?? i thought that would be bad for it and i also have a little jig for mixing fuel, call it the two gallon shuffle,  

ive gotta make up a dance too. i kinda just stand and shake.  it would be better exercise and more fun if i had some dance to do like you guys, lol.  any suggestions?  

mines kinda like the truffle shuffle but with a gas can  

LMAO  maybe ill try the napolian dynamite dance with my gas can, that would be interesting.  if i do it ill make sure i get a video of it and put it up on youtube for you guys.  

beaver, maintenance for a 2 stroke doesnt just mean oil changes and air filter services. how much time was on the engine after the last top end service?? bottom ends wear out as well.
let us know happened.  

how often do bottom ends need to be replaced
for 2 stroke 80/85s
125s
and250s

Not necessarily.  This could be a topic unto itself.  Running race fuel in a stock or near stock bike is wasting the race fuel and may actually make throttle response less than with pump gas (same if you run straight AV gas).

Most stock (and near stock bikes) may benefit from mixing some race gas (up to 50%) with pump gas to help with the quality of the stuff we get now days, but its not necessary to run 100% race gas (other than it smells good...).

I have found my YZ250 and son's YZ125 seem to run better on 25% race (105 Octane) 75% pump (93 octane) mix than straight 105 octane race gas.
