The DR650 thread

[Eddieb]

15/41 is stock and it should pull to at least 150 on that gearing with no issues.

I'm running 15/43 and there's no change in top speed but it's a bit peppier all over. Gearing may mask some of it but you still have issues that need to be resolved somewhere.

yeah ya right there eddie definately something restricting it thats needs to be sorted-

would be good if said bike could get down to waipuks place and compare apples maybe.
kinda one of those problems ya wana see in person and have a totu

5,000rpm max torque.
6,000rpm max power.

I'm running equiv to 14/43 for general use.

Mine runs 15/41 fine, but I think it runs a little hotter then most DR's. I find 14/41 drones too much on the long highway hauls and drives me mental.

[R650R]

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

If you click on the banner in my signature I've got over 10,000km of fuel history for my bike recorded. It's been handy for tuning as as well as the seat of the pants dyno I can see in real numbers what difference a modification has made over a tank of fuel.

My numbers say 18-19km/L from the FCR39 no matter the riding conditions or gearing.
18-25km/L from the DynoJetted BST depending on riding conditions.

Is the front edge of the rear tyre evenly centred between the 2 sides of the swingarm or does it have more clearance on one side than the other due to the sprocket etc?

I replaced my rear pads yesterday and when mounting the tyre I couldn't get the wheel to sit evenly centred between the swingarm even playing around with the smnail adjusters at significantly different settings and I can't remember if thats normal or something is out of whack.

The other bike is buried under a pile of boxes and stuff from shifting and I can't get at it to compare.

[gav24]

Not sure if its meant to be centred in the swingarm ( i wouldnt think so) but I did set mine using 2 long straight lengths of angle iron and getting it centred off the front wheel. With the bike on a workshop stand.
Was a bit tricky with the knobbly tyres, but with some patience and zip ties i got it done, and the snail cam was only 1 click extra on the right side to get the front wheel centred between the lengths of iron running off the sides of the rear tyre. I guess that gets them in alignment but who knows if the front wheel is centred...-and on it goes...
I must admit for the last 2 rear tyres I haven't bothered and just trust the snail cams to be near enough. I'll need to do it all again soon when I get round to making the gsxr rims fit...

[gav24]

My last post was pretty unhelpful!
How's this;
Snail cams both on 3
Swing arm to rim left side - 65mm
Swing arm to rim right(brake) side - 45mm

So not centred then! Hope that helps a bit more.
Sometimes I should definitely k.i.s.s.

Thanks Gav, mine is 20-30 mm out with the brake side much closer to the swingarm.

Anyone else got a comment in case both Gav and I are out?

I find the cush drive is a bit of an odd fit, it doesn't seem to hold in place like other bikes do. Maybe somethings gone astray there and jamming the show at an angle. The rear caliper is on a sliding float mount too, perhaps there could be an issue there?
Take a picture, someone here will have an ahh ha moment of clarity on behalf of you.
Haven't put wheel spacers wrong way?
Have you tried pulling out and starting over again?

Don't know if these will help or not

The rear brake is mounted correctly on the slider, the cush drive is sitting even the whole way round and all the spacers are seated good. The spacers and cush never actually came out, I lifted the bike onto my work stand, removed the axle and dropped the wheel just enough to pull the caliper off the sliding mount, changed the pads then reversed everything back in. Everything is spinning ok with nothing binding but sitting directly behind the rear wheel looking forward it looks odd.

So wheel turns ok?

yep it all spins fine
