Hi anyone know where to get a servo for a dt125. It seems to lack a bit of top end so would be nice if I could get hold of one. If it's anything like the RG though they're rare as hell. It's a 1997 btw.
dt125 power valve

They are very rare and very expensive. I considered it but in the end just pegged the valve open.
Take the exhaust off and get it so the outlet is bigger (you will see what I mean when you turn the valve) and smooth. Then peg the valve at that. You will have nothing low down (below 6k) but when you hit that powerband none of it matters lol. Mine would get through a head gasket in 300 miles when full power though.

Yeah I saw some on ebay but not for my 97 bike. It's OK how it is but if there's more power there I want it lol. Surely it shouldn't be getting through a gasket in 300 miles though?

Didn't know you could get them for as cheap as £20. When I was checking I couldn't justify paying what they were going for but I can' remember a price. Maybe I was just really skint and £20 was loads then or something lol.
It shouldn't get through a gasket that quick but it managed it. Maybe the head was warped but I got rid of it so will never know lol. I did used to give it some stick though.

The cables are no problem to get hold of on ebay. What's inside the engine atm then I thought they were just pegged shut and you put the servo on them to make them move? Not even had a chance to look at it so I'm just comparing it to the suzuki power valve.

Hi ordered a servo, just need to sort the pv out. Was following this http://dtr125.net/ypvsf.htm and it seems he just takes everthing out and puts it back the same? Also need the plastic pulley and housing, are they much from bike dealers?
