2002 dt125r rev limit??

[Calum]

@declan Open up a new thread bud please.

[Mitch_350z]

@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??

[Calum]

@mitch_350z It shouldn't pull well at the lower RPMs, but past 6 it should pull hard to 12. If it doesn't then it's not the powervalve causing the problem.

[Mitch_350z]

@calum ok thanks mate I'll have to do a bit more digging, just out of curiosity my other dtr I had was also a 2002 but had a 3 wire servo rather than the 5 wire this one has?? What difference does this make??
Cheers Mitch

Everybody has to remember that 99' onwards 3RM DT's are CDI restricted to 8,500 RPM...

So, don't expect anything like a 3 wire servo Pre 96' model.

[Calum]

@darty The DTRE's are not restricted to 8500. The DTR's may be.

[finnerz89]

@darty definitely not, my DTX goes way past that.

[Calum]

@finnerz89 Well, I wouldn't say WAY past. I think it's 10k. Because the Powervalve closes then and then it really struggles. But it's as simple as earthing the black and green wire then you get full power.

[finnerz89]

@calum I've had 12k a couple of times. Earthing that cable transformed it

[Darty]

@finnerz89 Yeah sick, the DTRs though - are different sadly.

DTRE/X use a non Restricted CDI.

2002''s are doomed to 8.5k.

@darty My '03 was de-restricted and went up to 11K+ NP's.

[Darty]

@cyber-ninja Tell you what, it's said that there were some 3RM CDI's that were Unrestricted from factory for last model 2003'

I can't remember the CDI code, if you had one, that was pretty rare!

[NINJA]

@darty I can't answer that for you as I sold the bike, but if it was an un-restricted CDI then yes I was very lucky indeed!!

[Mitch_350z]

@darty could this be as simple as swapping the cdi for an unrestricted one or is this not possible??

[Calum]

My brother had a 2001 DTR and it was slow as fook.

Although once derestricted it went like stink.

Pretty sure he swapped out the CDI though.

[declan]

@calum do most still have the reed valve behind the clock or is that only for speed not revs?

[NINJA]

@declan I believe that it's a sensor which forms part of the de-restriction system. It monitor's RPM's and when a set limit is reached it retards the CDI/engine from going any higher. Hence if you unplug the sensor then in theory your engine is capable of reaching it's highest maximum RPM.

[declan]

@cyber-ninja I have no reed switch I have no grey box in front of the oil tank but my bike is a pre 99 I can't find any restrictions

[Mitch_350z]

@cyber-ninja I have moved the reed switch behind the speedo but not unplugged anything??

@darty They are rare? I currently have a dtr 125 2002 (Registered as a 2003)
