Top End Rebuild Part 1: Power Valve Assembly

6:00
Hey RUclips,
This video (part 1) is all about putting your Power Valve back into a refurbished 2003 RM 125 Cylinder; please click on the time stamp to go directly to the part where I begin assembling the Power Valve. Stay tuned for part 2 (installing the cylinder). Thank you for watching!

Excellent

[@milkbones8617]

I am about to trade for a 2003 rm125 so luckily I can follow this

[@davidsandoval1089]

Bro, do the valves open at certain rpm? Or as soon as the motorcycle starts, they should already be working?

[@davidsandoval1089]

Bro las válvulas se abren a ciertos rpm? O en cuanto se enciende la moto ya deberían de estar trabajando?

[@nashgautney8117]

You take forever to explain things but good video...

[@JonStpeter]

Hey Nate, tell me about that cylinder jug, min is slightly different on my 04 rm 85 and I'm not sure how to find the difference for assembly. My jug is the B2.

[@watchnato]

Hey Jon,
Where have you looked? I usually get all of my parts from Rocky Mountain ATV; they have parts diagrams that show the exact parts you need for your make and model. I was able to send mine in to get re-plated. I was also able to clean up my power valve and re-use it.
Best,
Nate

[@MaxsMotoShop]

Top end of what???

[@watchnato]

Hey Max’s Moro Shop, this is from a 2003 RM 125.

[@RealEstateGettingStarted]

Or you could just buy a four stroke and not worry about it. I’m gonna just leave this right here...

[@milkbones8617]

Naw man I’m trading my 4 stroke for a 2 stroke right now, fuck 4 strokes, too complicated

[@joeymeyer8261]

2 stroke is freedom. Not feeling like your planted to the ground. And lets not forget they are twice as powerful then the 4 stroke in cc for cc. The 125s take on the 250 4 chokes all day. If you want to run a 4 stroke get a grunt quad. That's the only application I see useful for 4 chokes. Yard equipment. Not something your trying to have fun and go as fast as possible.
