some pics of the new project I think its a 85 125 going to fix her up for the wife to ride and i will use it as a second bike for fun




Shes a bit rough around the edges


But complete .   Will require a full rebuild still turns over but not much comp. 
It will keep me busy for a while and I couldnt let her sit any longer so I offered 100 bucks and the owner said take her..

bikes apart now couldnt help myself the piston is shot and has no ring at all.  the cylinder looks good head has a small mark on it where something (ring) has hit .

The piston doesnt have a number just the arrow does that mean its stock?

not necessarily....best way to tell what you have is to mic it.

piston is 55.95 std range is 55.945 - 55.960 .  Now what to do with the cylinder it looks fine to me but im a little confused as some people say i can do this others say i cant touch it.  can i just order a 56 mm piston.  thanx remember im new to dirt bikes but not completly stupid thanx guys.

[Foxx4Beaver]

more than likely you could probably run it through a hone real quick and call it good...providing it's within spec also.
otherwise, you'll have to have it bored.

thanx fox i will take cylinder into town tomorrow as i can only measure with my verniers at top and bottom.  I will get some figures and see from their need to split case anyways so im not in to much hurry just trying to keep myself occupied as it stops me from drinking so much hehehehe  thanx

[Foxx4Beaver]

what kind of piston are you planning on running...cast or forged?
forged will need .005 clearance between piston/cylinder.
where as cast can be tighter. 

I highly recommend going with forged.

i was just going to see what u guys say when it comes time to buying that   needs some bottom end work the previous owner has pulled it apart and i have a container with some random parts 1 has got me scratching my head Ill take a pick of it

[bens87braap]

any ideas what this is ?

[bens87braap]

found it clutch pushrod cant see the clutch working without it either lol

[Foxx4Beaver]

yup that's it.

[bens87braap]

I figured it out you just have to go for it,  The shift  mechanism had been pulled out and in a tub i managed to find all the parts and put it in the way it looks in the book then the clutch back on and it all works,  every gear is their and the shifter even returns back to normal spot,  Happy days on to the next part
