Cutting the video from time to time I almost got lost 😂😂😂 That's not a Ninja 🤣🤣🤣

[@Dubbisn]

Is this hos you fix it or adjust it?.. because i need to adjust mine.

[@UnrestrictedIsle]

The adjustment is done by pinning the cut out on the plastic wheel and feeling in the exhaust port (it should be flush)
You then tighten the cables finger right and back them off a quarter turn. Then lock them up 😁

[@Tizzypj]

Yo are you active mate

[@UnrestrictedIsle]

A little bit!
What’s up?

[@kingkong81icloud]

Just opened it fully and get rid of the electronic power value , I had 4 DT125R none had the electronic valve, just keep it wide open, that DT R don’t look as good as the 89 an up models I don’t know why they changed them to look like that

[@ell0hh]

the valve gives it wayyyyy more low end power.. I rode my 86’ without a battery for the first 2 weeks and then put one in which made the YPVS valve work and holy shit, it was a completely different bike

[@JP-fu8vc]

88 amd up:)

[@kingkong81icloud]

@@JP-fu8vc yeah, I don’t know why I said 89 , I had one on a G plate probably why

[@RetroYamaha]

Yes for bottom end & top end that's why they fitted the ypvs ​@@ell0hh
