When mine had the stock gearing it ran quite nicely up to 150. Now it tops out at about 135-140, but it gets there very quickly. I cruise at about 105-110 usually which is around 5000rpm. I use the DR for dirt just aout exclusively, so I have no need to go over 120.

Watch out for those sandy patches at hell for leather pace

Cool pic

And a bit of thisssss

( Point is .... horizons can be far, and I don't want over gearing .... guys riding with me, same bike, with -1 tooth have returned 20% less fuel range .... passop , is all I say !

After the twentieth stofgat at 190 + , you eventually stock karking yourself ! ( KTM950 ) ..... MOMENTUM IS YOUR FRIEND !

+1 , noted all I need is 11 to the liter

Consumption has improved though, time to raise the needle clip to it's top and final notch I guess.

Proof that sand demons can be overcome , after 140 km of this stuff .... again, stock gearing rocks !

And the DR is lighter than this KTM 950 ( I'm getting old ! )

I actually just remembered I changed my sprockets and chain before the re-build, got rear sprocket and chain for a bottle of brandy from a mate, I must check, never did a long ride since then, maybe my gearing is FUBAR

Ok, I'll stop posting teaser pics

?

Wildcoast · « **Reply #730 on:** March 21, 2012, 09:48:35 am »

16/42

DeepBass9 · « **Reply #731 on:** March 21, 2012, 09:50:38 am »

16-42 is standard

volroom · « **Reply #732 on:** March 21, 2012, 01:29:17 pm »

ok, we'll see what the fuel consumption is eventually but otherwise very happy with gearing. I'm not keen for more than 120km/h on dirt, want to keep to that rule no matter if it's a dirt highway - when going fast also not easy appreciating the scenery.

volroom · « **Reply #733 on:** March 21, 2012, 06:11:46 pm »

Have to say VM, those are awesome pics..wow. One day when I'm back in the Cape, I'll also explore the karoo's

Saturday morn coming has opened up, so I'm in. WC, is it going to be a hardcore technical ride? I won't yet have crashbars and bashplate on by Sat. Cool if we take is slowly? I'm still a noob in a sense when it comes to gravel

Wildcoast · « **Reply #735 on:** March 26, 2012, 11:27:53 am »

It is sat or sunday, check the planning a ride dualies to breeds neck thread, it's gravel and some 1st gear up the rock hill and down the other side stuff , pretty easy I did it a few weeks back.
Always take it slow I do.

Great stuff. will check it out.

UPdate on the dyno. So yesterday I rock up at Charlie's place and we can't find the dyno kit, then we eventually get it. As we try to get the probe in the zorst there's an obstruction..the okes that made up the zorst decided to weld a plate in the middle to make it nice and quite it seems...Can't get the probe in deep enough..so, I'm gonna take a frieken welding rod and make a hole in it. Charlie says that an entirely open pipe is extremely loud, to the point where it's not a good thing anymore.

Wan't to try and avoid making the hole too big then, but..that obstruction is affecting the performance in a bad way. There's a leak as well on the zorst that I have to sort out again..

If all goes well I'll have the bike dynoed by Thursday. Also connecting cigarette lighter socket. Can I sommer connect the negative to any metal on the bike? Live goes on pos of battery, negative (earth) anywhere?

IMHO the best solution for a bike which at some stage will need a dyno tune is to use a threaded probe into the manifold / header pipe.
Very easy & cheap to weld in the threaded bit to take the probe, the probe is where you want it and once you're oune you just plug it up ready to bve used again whenever necessary.

SuperDavexlv750r · « **Reply #738 on:** March 27, 2012, 11:20:49 am »

@Le Cap -where would you position it on the header? And what size hole should it be?

volroom · « **Reply #739 on:** March 28, 2012, 07:24:30 am »

Also connecting cigarette lighter socket. Can I sommer connect the negative to any metal on the bike? Live goes on pos of battery, negative (earth) anywhere?

Another questions, what is maxium voltage battery provides while charging, while riding at say highway speeds?
If I fit LED spots, I need to know.
Thx
