Iv had the exhaust off pal.as we speak the valve is open n goes like a rocket

My servo must be nakered then coz iv tryed the powervalve half shut and the bike was shit lol must not ov been opening but now its open it goes like train

Yeah it helps pal anything is beta than nowt ill have a look wen I finish work.shud it open wen I open the throttle coz there is 3 cables

Wat wud you say the proper position is mate

Not too sure about uk spec its a 1993.the bike runs fine justabit slugish on bottom end hence the powervalve is open.not too sure wat I need to do for it to work properly or wat is stopping it from working correctly the servo has 3 cable and it says 4fl

Yep it turns wen I turn ignition on and I have a hell ov alot ov top end but not much bottom..how do I resolve it..wat makes it open then wen riding.

I I have a tzr 125 with electric powervalve how does it work.coz im not sure if my powervalve is moving.my servo has got 3 cables connected thanks jonny

Hi I hav a 4hw tzr is there any other modals wat are the same parts I need a new basket plates hub n springs n bolt just findin it hard to find one for my modal

The old basket has too much play in it

Just basket etc.

Just bort a barrel so thats the powervalve sorted...will a 4dl clutch fit my 4hw.

The bolt side ov the powervalve.i think a may just hav to get a new barrel.oh well thanks for everyones help

Your rite they do bolt together but where the bolt goes thats the bit that has snapped

My tzr is a 1993 4hw but the barrel is a 4fu and yess it does run.i pulled the engine out to rebiuld or refresh and found that I need a new clutch basket.the basket is not a problem as im watchin a few on ebay but the power valve shaft in the barrel has snapped and they are discontinued.really findin it hard to find one

Rite well my bottim end is a 4hw modal but the barrel is a 4fu wich I think is a tdr is there any other barrels the same or any other powervalves the same
