New pipe fitted...I estimate about a 7kg weight saving by losing the twin pipe set up....

Nice pipe...remember the days when we had leaded petrol and a proper running engine was indicated by the white residue on the exhaust pipe

Soon I'll have the DR dynotuned. The guy said something interesting: that there shouldn't be any exhaust leaks and that the packing in the exhaust canister should be tightly packed. I guess if that wasn't the case ( the packing) that air could get into the baffle and mess with airflow or something. SO, about to drill out the rivits to check the state of the packing-add some of needs be. Does anyone have any relevant experience?

Here is a picture of my DR650R before I lost the pipe on Himeville Road.

Just back from 9 days in the bush building a 15 sqm roof structure under a tree destined to one day fall down and smash it .... hahahahaha.....goodie I see some progress while I've been gone !

NICE PIPE WC !

Just collected my new front disk rotor from Suzuki and again was pleasantly surprised they could dig out ... from stock ... a new O-ring for the oil return pipe ( on the left of the engine ).  Must be a special compound the old one is blue-ish the new one is black , maybe EPDM ?

With these installed the only last issue I have is the spring free length of the forks is 28mm under spec with sag , so I will conjure up some spacers to correct that on the cheapskate , and the last mechanical issues of my ole DR will be put to bed.

My Velvaglo Khaki DR parked outside Suzuki South this morning caused a bit of a stir , it was a busy morning with lots of guys testing the ZX1000 , but there was a gathering and commentary of note , one hardcore Austrian adventurer who crossed Africa a few times in a Jeep was particularly approving of this bike, and model in particular.

Always the first big comment from anyone who has done any real Africa time is " NO ELECTRONICS !!! "

Ja le Cap had a really good laugh at your HP2 chirp !!! I wonder how many bikes Uitspankraal has drowned ? : )

I got to know the owner of the farm Uitspankraal but for different reasons , pop rivet through my buddies KLR rear tyre. The shit that falls off bakkies is more of a threat to your days riding than most rocks and thorns.

The worst GS story I heard was poor ole Wayne F from Auto Atlantic drove a bakkie to deliver Roadside Assitance to a tourist on one of his MotoBerlin GS12's ....in Calvinia.

When he got there, he switched the kill switch to 'Run' , and hey presto , the fat flabby pig bike started. *sigh*

Lekka ride SuperDave! I'm thinking of planning a ride. The DR will be done in about 2-3 weeks time. I'm open in April. Maybe Namibie even Botswana. But if possible want to keep it to not more than 5 days...

Even if your not interested in a trip like this, what about a weekend trip? Some ideas, some suggestions, some comments? Sorry Veemax...this one is for the boys up in the vaal, but you can always come and visit your cousin..?

My wife and I are riding Apr 11-25 for 14 days straight , right smack Oh So Not In Easter or School Holidays etc , when we can OWN South Africa , and the weather is generally brilliant , and all the police are resting after pulling heavy shifts over Easter Madness.

I used this sweet spot before to ride the 29th Parallel , CT to Richards Bay across the country to Port Nolloth , and home , 4774 km in 6 days / 5 nights , the only place we needed rain gear was the on the N1 out of Cape Town to the top of Du Toits. But this ride was brain-out bad-ass 1200cc Suzook Oilheads ( spot the trend ? ) running BT54's , with average speeds that would have a Magistrate give you a snot klap.

Ja you Vaalies must enjoy yourselves when you can , shame man.  :pot: , but I still reckon when your bikes are at 100% we should convene someplace ( like my 'farm' would do ! ) , or someplace midway , and celebrate this ole DR good and proper huh !

I fitted the new O-ring yesterday oh so carefully and hey presto looks like my engine has gone all oil-tight , so now not only is it NEW but it doesn't emit hot-oil-smell that one tiny drop of oil can produce. That smell I guess old Brit bike followers consider normal !

I'm off to test an F650Se Husaberg this morning , 60 bhp on 112 kg , I'd better not ride a DR after that ...

It's not for me , been there done that with an SM610 ( kinda ) , but for a mate. What I like about our old DR's is they don't measure service intervals with an Hours Operation meter.

And servicing doesn't mean inspection of main crank bearings and rocker shafts .....

Ja the step from 45 to 60 bhp is not worth the spanner time to this ole toppie any longer !  :D

Veemax throw your fork springs into the bin.

For illustration have a look at the spring equation for coil springs and check what happens if a spring gets shorter with all other parameters remaining the same. Puting preload on will not help but rather collapse the springs further and possibly within hours or days. Also keep an eye on block length of the spring / spacer combo which must be less than what you've got between damper piston and cap when bottomed out else you will produce expensive scrap when hitting the first pothole.

Thanks Le Cap , Progressive here we come. This ole DR is gonna WORK so I'm gonna take your advice ... and I hate a mushy front end even more than a mushy rear ( on , well , most things )

Progressive Springs Kit $ 103 ordered. Shipping $ 25 , not bad , eta < 7 days ??? Lands/clears at R1200.

Come this far , might as well go the whole way to a decent ride huh !

Must be a total of R42-R45k all in by now , but hey , sold my KTM for I think R61 000 , am happy, and the wear parts are NEW.

Mushy front end..besides taking out springs and checking length, what would be warning signs? Also-the danger of bottoming out on the front at speed? What might cause this? I'm no expert

Since the Sani ride-I been so busy that I haven't had time to ride my DR. Also had top give some attention to my XLV 750 R failed fuel pump but that is another story.

So about aweek ago I climb onto bike - pull de compression lever and start process of kick starting my DR.

No life because when I release the decompression lever and kick it feels like it it still slightly open. IOW little to no compression.

Now I ask myself how can this beas the bike was running 100% until Igot home and switched the bike off.

So I thought - (but wasn't convinced) - maybe the valves clearances had loosened to such an extent to keep the valves open all the time.

Stripped off all the plastics -  and tank as well and have removed the inspection covers for inlet and exhaust valves.

Need to still drain oil and remove magneto cover - but somehow I think I am wasting my time. Is it possible that the compression ring could have broken if bike was running too hot and now that it has cooled down - broken?

I will check the valve clearance but suspectthey have tightened up and not loosened based on my preliminary inspection.

That happened to my bike, as well. After a 900km day pushing the bike hard, I got home, parked the bike and it never started again, no compression. The oil level was too low and the rings were chowed. Took a top end rebuild to fix. I am now very careful with checking the oil..!

Sttering gets nervous especially on the brakes as the soft front changes & upsets the bikes steering geometry.

If the springs are really bad they will not fully extend the forks any more. Loosen upper triple clamp clamping bolt(s) & remove fork tube plug (front wheel in the air). If the spring does not push against the plug = if the spring is not preloaded the springs are scrap. This typically happens if the spring has sagged more than 20 - 40mm. You obviously have to remove any non oem preload spacers for this test.

I can get Wilbers springs for the old DR just as well as for almost each and every other bike build over the last 35 years or so with my next shipment.

Re the bike was fine, got home & parked now no compression: Normal scenario. The bike will run fine on very little compression. Once you switch it off it's finito and won't start again. Low compression will always cause starting problems first regardless if the compression is low because of worn rings & cylinder or leaking valves.
