The DR-Z400 thread

[Alpha Solo]

Yellow plastics have gone.
17ltr Safari Tank in Yellow - $300 + P&P (was $500AUS + customs)
Bash Plate (SW motech or Moose Racing it looks like) $100

Right now my drz is geared 16/39. I need to get new sprockets and chain shortly though any wondering if I should keep that configuration or...? I don't know that my bike will ever see the dirt it only sees the road/track so I don't really know what to do? Will be used for touring a fair bit. I'd like to get it sitting at 100kph quite happily. It can sit at that right now, or maybe about 110kph. Thoughts?

This guy seems to know a thing or two about DRZ's

Hope it helps, six gears would have been the easy answer......

Our DRZs have rightly been criticized for having too close a ratio gearbox for road and trail use.
It seems that the answer to this is easily available for under a $1000!
ACT brand, Wide ratio gears, US$620 + fr + gst.
Has anyone installed these ?

[Padmei]

There was the chap from Chch if i remember correctly that got a Pommy eng outfit to make up a 6 speed box or widen the ratios or something. I believe they were a few grand back then for the box. They would have sold hundreds of thousands more DRZs if they had included a 6th gear

There is a UK, Nova brand, Five
speed, but it is £1050 + fr+ gst, so not much change out of $3000 NZ.

There is a UK, Nova brand, 4 speed, but it is £1050 + fr+ gst, so not much change out of $3000 NZ.

Nova are the guys who made the 6 speed for the kiwi bloke. They are also the ones making the DR650 3rd gear replacement.

I reckon 5 was fine, they just needed spread out a lot more. Lotsa gears is good for peaky wee engines but there's a good reason the big MX bikes went to 4.

Shit loads of torque and 60hp helps.
The MX bikes are also tapped out around 100kph too. They can get there bloody fast though.

And they're tuned for peak HP, not torque spread, so those 4 are still pretty close.

The point is with the torque curve of a modestly tuned big bore trail bike 5 gears is plenty. At least it's plenty for me. In fact I geared my 525 up so it's effectively a 5 speed, never see 6th off road, and bugger all on road.

Maybe it's just me but I find changing gear to see a drop of just a thousand rpm or so all the time tedious, if I want another gear it's because I want a noticeable change in power/traction.

A new rumour suggests that a couple more 400SM's could very well be making an appearance in the HB adv ranks, this year.

[RMOTO]

A new DRZ400 wheel set going for a good price...

Hey guys, I have recently purchased a 2001 drz and love it, apart from this week. I was commuting to work each day on it and then last week I had a week off and went down south. Came home and it wouldn't start, it would crank but not start, battery is charged and spark seems ok. Over the last couple of weeks it seems to like the choke more and more? Could this be a fuel blockage?

Any recommendations on well priced bike mechanics in Auckland that could have a look at it for me?

Thanks!

Undo the bolt on the bottom of the carb. Let a little fuel through. Do it back up. You should find it’ll start quite easily. My DRZ hated stale fuel so I got quite good at this. The bolt can be a bastard to put back in, so undo it until there is only about 1 thread holding, just enough to let some fuel dribble out. It won’t take much.

If the problem is happening every day, it may be something more serious.

[Nacnud12]

Thanks for that! All sorted, last owner hadn't ridden it for a while and the carb was full off crud. Good clean out and it's good as new. Has anyone on here done the air box mod? Also after a factory seat if some one wants to get rid of there one.

Thanks!
