2002 dt125r rev limit??
-
Hi all I've recently purchased my 2nd dtr which is fairly standard other than a dep silencer, after changing all crankcase bearings finally got to ride it
it only seems to rev to 7500rpm?? It seems to back off after this my other dtr was also a 2002 and didn't have this problem?? Any ideas what the cause could be??
Cheers Mitch -
Sounds like the bike is still restricted.
-
Oh right?? How do I go about derestriction as I've read about a black and green wire behind the headlight but can't seem to find it??
Cheers Mitch -
@anthonypearson I'd say pv not opening mine did it cause of a dead battery the other day and it was horrible like a cheap 4 stroke make sure it's opening bud
-
Ok mate I'll take a the cover off and have a look
Cheers Mitch -
It's the powervalve bud.
-
What do I need to do?? I've read assorted to do with a reed valve switch and powervalve wires??
Cheers Mitch -
@mitch_350z quickest, dirtiest solution would be to diwconnect the servo, pin the valve so it is flush with the exhaust port, then ride it.
-
@calum oh right is there any way I could solve it without loosing bottom end power??
Cheers Mitch -
@mitch_350z Yeah fix the servo. But doing this will help to identify the faulty component.
-
@ does it do the cleaning cycle?
-
@calum I don't think there is a fault with the servo?? It works perfectly fine upto around 7000rpm??
-
@declan yeah it does the cleaning cycle as normal so seems to be working
-
@mitch_350z It shouldn't close at 7000 mate, not even restricted. Restricted dtre's close at 10.
Sounds to me like it is simply not setup right. Closing when it should be opening.
-
@calum I've set the pv flush with the top of the exhaust port it's a little off the 'u' and hole behind the cover but is spot on?? I'm running out of ideas??
Cheers Mitch -
@Calum wait a min buddy are you telling me my dt is still restricted it redlines around 8.5?
-
@declan Yeah should pull to around 12 mate.
@Mitch_350z So long as its flush with the exhaust port that's the main thing.
How does it ride now?
-
@calum I know this is the most asked question but I've not seen no reed switch do you want me to start a new thread?
-
@declan Open up a new thread bud please.
-
@calum it seems to ride better when pinned but still only does 65 max and doesn't pull too well in 6th?? Struggles a little to rev up to but don't know If this is because of the pinning??
