Great work, thanks. I have a DT125R here in the UK, they aren't fitted with the PV servo as std, I have fitted one to mine and it makes a hell of a difference to the performance, now yours is working it will make a great bike even better.

its night and day difference! thanks for leaving a note and watching!

I've got a 1988 dt200 very similar bike and I've been having issues with my power valve for months! This video definitely gave me a better understanding of how it's supposed to work. Thanks for the great content!

I bought at dt200 that was rebuilt by the previous owner, the bike was gutless. The servo was moving but upon inspection in the exhaust port i found the power valve was upside down. Cleaned it up and installed the correct way. The power differences was mind blowing lol

Night and Day - A lot more snappy bottom to mid range. Really Livened up the bike. Thanks so much for your insight in this!!!!

Excellent video. I wish This had been available 6 months ago. My servo wasn’t working - same as yours the motor wouldn’t move. I had to buy one from ebay $$$! The 3ET is rare as it is the 3 wire servo with controller onboard - other ypvs have separate controller box. Can I post a link to where you got your new motor - I’m going to repair my old one now!

Hi there isn't there another more powerful Moto what would fit ? The one you put on seems slow in motion it's meant to be more faster in the pv cleaning cycle when it makes the noise thinking maybe more powerful battery similar in size may be more beneficial as to rpm's

U want to get a dep exhaust for it because some standard exhaust have baffles in them to restrict the power to specific hp to specific bike licence

Hi there, how it was without the valve not working ? I’m going to swap the engine and installed in a small Yamaha blaster for my son but dot know how to make the valve working , there is not harness or wiring on the blaster to give valve the necessary info to make it work , any idea? Can I just leave the valve wide open and the engine still will work ? Thanks a lot

it worked fine with the valve wide open. Was still a powerful little bike. But the Power Valve adds snappiness to the bottom RPM

Mine quit awhile back and its the yamaha chip i think, because the motor works and the capacitors on the circuit board are good so I bought a new, old stock dtr125 3 wire servo on ebayuk, it was from a yamaha dealer, it never even had the grommets, the tzr125, dtr125, sachs 125, Dt200 R 3 wire servos are all the same, I fixed my DT200L servo by replacing the motor, thank god because the controller is seperate, you can pin them open but you loose all bottomend basically but once it hits 6000rpm it hits like a freight train lol

thanks for the insight - will definitely help other viewers who have YPVS issues beyond the servo motor! I agree you could leave it open but its a different bike and loads of even power and torque now the YPVS works - wheeeeeeeelie!

Yes the engine still works with the valve open. And it still has good power. The valve gives quite a bit more snap on the bottom, but if you have never ridden with the valve working, you likely wouldn’t even notice.
