RD 125 LC MK3 YPVS PROJECT £150

[cubz]

Hi all
i am a noob to this forum stuff so please bear with me. I used to own a rd125lc back in the mid 90's and have always wanted one again i have just picked up this mk3

for £150 quid she didn't run at first but after a few minor adjustments to the wiring she runs fine, it was from a young kid who didn't have a clue. I'm planning a full rebuild and looking for a belly pan and a few other bits and pieces. Anyhow what I'm getting to is i would like to get the power valve working and derestrict it and was wondering if anyone knows what restrictions are in place and (i know a long shot but) does anyone know where i could get servo and cables etc to get the power valve working?

the bike has a
34x01 y-1 cylinder (does anyone have info on this?)
mk1 stator and flywheel (plan to replace with mk2/3)







added the picture for you cubz... ;)gaz

Have a search through this section and advice section m8.Has been discussed.
The servo cables,adjusters,rubber covers,end cap and pulley are all available new from yamaha. Your local dealer should be able to order in for you. The pulley the cables attatch to is the same as the 350 one.
You will also need a 350 end carrier for the right hand side of powervalve if its a non working model
Hope this helps m8

with matching numbers, also how many did they sell, i know it was not a lot due the tzr coming out

[cubz]
