The DR650 thread

[butcherboy]

took the bike to the mechanic and he pulled the plug out of the back of the ristricter on the carb bike pulls to 7000rpm with ease in every gear except 5th it will only get to about 5800rpm and wont pull is this a gearing issue

[butcherboy]

I might try gearing the 750 so it does 10000rpm at 100kph then

I'm with Bart, that lil piston already sounds a bit buzzy at highway speeds and above. First gear already feels to low to me and the only benefit I'd see is in river corssing or tricky obstacles.
I'd rather have it set up for doing whats best most of the time which is 95% a long way away from first gear.

Back to that other chaps bike I've read somewhere that the marving pipe is little more than a cosmetic difference from stock and similar in weight and restriction, perhaps its strangling all that extra air and fuel that your trying to feed it???
What does the bike do if you very slowly roll off the throttle from your max speed at moment?

Perhaps we should all do a fuel challenge on the next group ride. Mine does about 4.5L from Napier to Wairoa, 750 sucked through 7L on same trip yesterday but it was moving a bit quicker than the DR does

when you slowly let go off the throttle it slows down the same as it used to

[butcherboy]

Put it back to stock? They are good for about 150-155 standard.

What sort of economy are you getting? something must be out with your tuning if it's only going that speed.

even at stock 130 was topps with me on it

Im not concerned at all where my back wheel is in relation to the frame, I just worry about the sprockets being lined up, with the chain loose, slowly spin the back wheel and watch carefully where the teeth on the back sprocket engage the chain at the bottom, if there is any sign of the teeth trying to push the chain away before the chain engages with the sprocket then it means that on one side the side links are rubbing on the teeth, then its out of line, if one side of the tooth is polished and the other is dirty then that is another indicator.
Draw a straight line on the ground and push the bike along keeping the front wheel exactly on the line. after a couple of metres, stop and see if the back wheel is on the line, any mis alignment and it will be off to one side.

Ooops, the subject has changed while I was typing this out.

I'll check mine.
My adjusters are one notch apart (right one is 1 notch more).
I used a chain alignment tool to find that out.

My '90 TT350 is fine.

I'm still suspicious of it being a carb problem.

One way to tell is to try it on a dyno to take rolling and wind resistance out of the equation.
Then you can also crank up the resistance and see what happens.

A 14t sprocket wouldn't hurt anything though and would make everything about the bike feel better.

thanks for the help ive ordered a 14t and had my mate take it for a spin last night he is about 50kg lighter and got it upto 140 when he got a bit of tank slap so he backed of but said it still had pull, it might not like the weight and wind resistance i create my mate has a cbrr 600 and cant ride behind me i create to much turbulance(he doesnt stay behind me long and usaly has a good rest by the time i turn up if i wantedto go that fast id buy a sports bike)

Thinking about adding a dr650 to the stable and it appears some have the speedo calibrated in mph. Are there other differences between these and the kph bikes such as any engine restrictions etc. Thanks in advance.

The speedo is not so much 'calibrated for mph' but has a mph face on it. The taillight is also probably a different style to the NZ ones which are more flush and presumably the headlight is the NZ one that points to the left for WOF purposes. Other than that I can't think of any other differences.

It may have the ugly tail light and muffler with 2 bolts under it (one at each end).
If it does, then it's a US spec one.

Same as NZ but 1 tooth more on the rear sprocket (42).
No engine restrictions, just different jetting to suit their fuel.

I've got an almost unused KPH speedo here.

[gwynfryn]

Thanks, so not a deal breaker been a US model.

Nope. Had one of them myself. Just difficult to get used the the handlebars being on the left.

[gwynfryn]

Ha ha. Actually off to look at a xr400r an oldy but a goody hopefully. Original tyres, rego on hold. Nothing like a project now that the rain has arrived.

DR900...


Galfer...

As much as I can appreciate the individual upgrades on the bike I think the sum of the parts is hideously ugly. I don't know if it's the colour, the front guard, the position of the handlebars or all 3 together but that really doesn't do it for me.
