Yz 125 bike help please!!!!!!?

not sure on year[1990-1993] ..doing a rebuild on a bike..how do i cheack year..and i need a service manual so i can put wireing and pipes bck together....how much would it cost to get it boared out and an oversized piston inserted?

Answer 1

not sure you can bore that out.. I belive the cylinder is nickle coated. I think you have to buy a new larger cylinder and piston... not 100% sure but am pretty sure they can't be bored.

Answer 2

On the frame (near handle bars) there should be like a serial number stamped into it.

This will tell you everything about the bike!

Just contact your local post office to get the information.

Try searching on google for a manual, that what i did for my honda or you could contact honda.

Another option is to try bookshops or libaries.

And if push comes to shove then try a garage.

Hope this has helped.
