What other year cylinder head will fit a honda cr 2003 125


I searched for this and found that no other machine has this cylinder head, and that it appears as though there were 2 versions of the same head made for that year. My link below is for Bikebandit. I did a couple of searches for other machines that may fit this and found none. Good luck on fixing your bike.

What oil to fule ratio must be used on my 2003 honda cr125r


32 to 1. That equals 4 ounces of two stroke engine oil to one gallon of gas. DO NOT use motor oil. Only use two stroke engine oil.

I need to rebuild my engine.


You're better off buying a 'crate' motor instead. Rebuilding an engine is seriously complicated, but dropping in a freshly rebuilt one is not that bad. You can also try the local junkyards, they often have complete engines for sale. The nice thing about crate motors is they usually come with a warranty, I doubt a junkyard motor would.

Cr125r 2001 cant start after changing piston and cylinder


hi mate you need to adjust the float if theres to much fuel going through you need to take the float out and adjust it to the manual specifications but remember slot the pin out and take the float out but watch the little valve which stops the fuel where the little valve is hanging from that is the part you need to adjust

What year model cylinder will fit a 1985 Honda CR125R dirtbike. and what year engines will fit this year frame?


the bikes and engines are always changing for the never ending search of improvement. While the answer isn't definite, I hope that i can help.
Depending on if the cylinder head can be re-bored or if it has a coating like Nikasil will depend on the ease of obtaining a head. Many shops can machine a head to fit the motor...and there are many motorcycle savage yards that may have what you need. If all you need is to re-bore the head then that is far better and more cost effective (as a used head may need to be re-bored anyways) As far as the motor fitting into a frame..measure themotor and the placements of the mounting brackets...new brackets may need to be fabbed but it can be done with a little imagination...and money doesn't hurt either
