2003 DTR Powervalve issues

timprice

My bike is dtr 125 2003 model and wont rev over 6 to 7 rpm i have cleaned the power valve and refitted it and its still the same any help would be great

So we're seeing this a lot recently.

The common scenario's we're finding is that the CDI's are starting to fail.

Can be a costly thing to try.

I'd would pin the valve open for now. See if you're getting full power.

EDIT: I've renamed this thread to be more helpul.

Just a friendly reminder, we're not paid to help you.

You've just come on here, not even introduced yourself and expect members to help you. Remember we do this because this is our passion.

If you're going to be rude/impatient, then take your bike to a mechanic and spend £1000's getting them to sort it out.

Members will chime in if they have something to offer, but don't force it down their throats please.

Cheers,

Calum

@timprice not the most knowledgeable but I’d be inclined to think it is the CDI but don’t take my opinion as law

Can literally buy brand new CDI's, so not sure what you're on about bud.

My powervalve would go through the cleaning process but not move once the bike was started. Got another cdi unit and it then worked great so I would go for a cdi unit. When I started mine it went to the close position and stayed there no matter how much I revved it.
