Question about a possible timing mod

Recommended Posts

I was told by a friend on another board that there is a mod for the DRZ that tricks the timing computer into thinking you're always in 5th gear, thus giving you more power on the low end. Something about installing a resistor somewhere unspecified.

In searching this forum, I was unable to find any info on this mod. Is it real or was my friend blowing smoke?

Idid hear something similar relating to the Hayabusa though, maybe thats what he was thinking of. What are all your thoughts?

Ahhh, thanks for the info. I'm glad I don't have to go tearing the wiring apart now. :cry:

My buddy, despite the comments from this forum, is still insistant that there is a TRE mod for the DRZ. He said his brother did it to his '02 DRZ-400s and the low end was vastly improved.

There can't be. The DRZ doesn't have electronic fuel injection so can't vary the fuel mapping for different gears and revs. The only thing the CDi can do is vary the spark timing but, since it doesn't take any reference from the gear position indicator, it can only be advancing or retarding ignition according to engine revs.

Well then,,, by all means enlighten us..

But please,,, we need more then,, So and so said it worked...

Were damn sure,, it is not applicable to the DRZ,, based on what we know of the CDI, and the other wiring circuits involved.. So,, If you can,, find out what was done,, how,, for what reason.. And ask them to explain the reasoning for the mods.. as so far,,, what you have brought out on this does not make any sense..

Thanks for asking,, This should be interesting one way or the other..

.. I just had an vision,, This thread and others like it,, are like an on line version of “Myth Busters”

:cry:

Just so you know, I am NOT doubting your expertise on the DRZ. I am merely relaying what I have been told.

From what has been said here already I am very inclined to agree that there isn't a TRE mod for my bike.

He did say he'd find out from his brother, so... hopefully I'll know something more before too long. Perhaps the guy did find something new.

simply inform him that the gear position sensor on the drz only makes the nuetral light function.

just becuase its a suzuki doesnt mean its a fuel injected suzuki.

That wiring diagram is hard to read. Know where i might find a better one online?

I was looking at the wiring diagram and have two questions:

1. Any idea why the neutral switch has three wires? Two would be enough, surely?:

black/white=earth

pink=feed to the CDi

blue=feed to the neutral light

2. Is the white wire from the CDI to the coil a reliable source for a rev pulse?

Cheers

the pink wire is part of the safet switch circuit as well.its either open or closed to ground.

as far as the white wire goes,it depends on waht your looking to do.that where i clip the inductive lead for the dyno tach.

      Hi,
      I have a 2003 DRZ (actually a KLX400) and the head tube bearings are shot.  I ordered a new set to install but I'm wondering if anyone has any recommendations on other parts I should replace while I have the front disassembled.  I was thinking about new rubber fork protectors, but are there other things that wear out on the DRZ front ends that you can only get to when disassambled?
      I also broke off a replacement key that I got for the steering lock.  I must have been made of cheap pot-metal.  Should I just remove the whole lock mechanism?
      Any tips or tricks for getting the old bearings out and the new ones in would be welcome!
      Thanks!

      Hey Guys,
      I recently bought a 2003 DRZ400S and thought it would be a good idea to check the valves clearance etc . I timed the engine on TDC with the magneto mark aligned as per the manual but I find the cam timing slightly odd. The arrows pointing upward are on the 1st and 15th pin as they should but with the magneto timing mark aligned they are not perfectly straight. Same goes for the arrows that should be parallel to the cylinder head casing. Is this normal or should they be absolutely perfect ?

      My bike was stolen, so I'm liquidating my spare parts. 
      I took this off my S and replaced it with an SM unit so my speed would be more accurate with the street wheel setup.  I no longer need this spare.  I greased it regularly and it was in good working order when I removed it.  Included is only what is pictured.  Cable not included.
