Alot of pics! is my piston gone?

[UniRacing]

Does my engine look bad? my piston,rings,ports,head and sleeve

 

[blasterdude14]

to me it looks bad but im not exactly sure what a bad piston looks like except for the obvious stuff like cracks

 

[blasterfreek30]

looks pretty normal to me, did u have any problems that made u tear it apart??

mabe could use a set of rings or a new bore

 

[UniRacing]

Well its not cracked..but its discolored and alot of carbon build up
also my rings are loose on the piston which makes my piston move slightly back and forth inside the sleeve

Edit:

No problems just its a 1996 and i know it hasnt been rebuilt since then so i was wondering how bad it was,im actually considering port work from kennedy and new piston,but how long will mine last?

id get it honed rering it and throw it back together

Thats the answer i was looking for!

Thanks,i wasnt sure if i could do that..

How do i clean the carbon of my piston and the head?

the second pic of the piston doesn't look good, around the bottom ring. i'd check the cylinder to see if it needs bored and put a new piston and rings in it

 

[yb200]

yeah the best thing to do is take it to a shop and see what they tell ya

Thats alot fo carbon built up right there,it isnt jacked up unless that wont scrape off...but im not worried about that dirty piston if a stock size piston and rings are available somewhere?

Edit:

i dont want to take it to my local yamaha shop,they are way to expensive..i beleive i could hone it and put a new piston and rings in,where would i buy the stuff though?

 

[yb200]

find a shop to get it honed not a dealer

 

[UniRacing]

I wouldnt trust these hillbilly atv shops around here! <LOL>

All we have is a performace plus (yamaha)

and yamaha of memphis (yamaha)

and there both super expensive

 

[yb200]

i had mine done at sturdevants machine shop idk if ya got on around there cost me 45 for a bore

 

[UniRacing]

You bought the piston and rings set,took it and your motor to them and they bored and honed it to the size piston you bought?

 

[yb200]

well i took it in they told me they needed a piston to measure it for the bore so i went home got a piston kit from rm went back gave them the jug and the piston and went back and got it like 3 days later and 45 bucks later.....took it home put it back together and i am on yr 6 on this bore... but i think when i do my frame off this winter i am going to put a new set of ring in it just because

If you wanna get that carbon off,go to your local auto parts store. Pick you up a can of "sea foam" fill a gatorade bottle with it, drop your piston in and let it soak over night. If that don't get it off nuthin will !
