I just bought a new cylinder for my 01 rm125 from partzilla. My current head has a cast section on the left side where new one is open. Am I missing something??

Does the part # check out as an actual 2001? Hard to see here but my 2003 had the open version for powervalve assembly (behind the thick black hose).

Part number is 11200-36840 which is for k1/k2. I googled 01 rm125 cylinder head and all images had the open power valve. On partzilla diagram, there doesn't show a cover. But there is two threaded holes so im assuming there is a cover plate?

I think the one you had was a 2003. The one you bought is 01 or 02

Bike was used and current cylinder had been sleeved. Don't know if it is what came on the bike stock. But now that I have the new cylinder, what goes over the new opening? The diagram on partzilla doesn't show anything covering it.

That was meant for Seth.

On the 2001-2002, a metal wire actuator comes out of the bottom end to actuate the power valve. Additionally, the recess on the cylinder is for a spring with a turn key on top, that is covered by a plate with two bolts to hold it in place. The power valve on 2001-2 is adjustable.

The 2003 was a single cylinder year, and I think they changed the power valve setup so it didn't have the adjuster. 2004 was a longer cylinder, as was 2005 but these have different powervalves.

I think you had a 2003 cylinder and I think you bought a 2001-2

Awesome, that's the info I needed. Next question is will powervavle from this cylinder work or will I need one specifically for an 01/02 cylinder.
The parts were on a different diagram so that's why I didn't see them.

I would imagine you are going to need to source many parts for the new cylinder.

Would I be better just swapping the 01 I bought out for the 03 cylinder and reusing the powervalve? Some of the parts are "obsolete" and would be another $400 to buy them . Is there an advantage to the adjustable powervalve? Why did they discontinue it. Gotta love used stuff.

i would just find the most inexpensive way of getting the bike running again.

Ive never had a 2003 model, but i think thats the cylinder you have on the bike originally- i would try and get that verified.

Im good with that. I just added all the parts for new power valve and it came out to $612 without shipping and there was one piece that was obsolete that I would have to hunt down. I'll verify the head was an 03, return this 01. Thanks for all the input bruce

Good catch, I totally forgot but I believe my cylinder was a 2002. I have had several bike since and had thought I remember the 02-03 being the same but you are probably correct.

I have a complete 02 cylinder with power valve assembly.
It ran great but the transmission started popping out of gear so I parted most of the bike out.
