How much of the airbox did you chop on the new DR Veemax? Did you jet her up?
Air is thin up here  :biggrin:

Sjo WC - going all the way eh? What would you reckon she'd be costing you at the end of the day? I'm keeping my mods modest for now. Don't want to spend more than 5 grand on it.

I think I'll do the crashbars - if you also want to have them made up by Groenie, let me know and we can ask him to do 2 sets, maybe he'll give us a discount.. :peepwall:

There's very little of my airbox left...will post some pics later. I had this idea of some material that you could cover the holes with that still breaths but helps keep out the dust and..water. Walked in Mica the other day and saw this plastic sheets that'll breath. difficult to explain, let me take some pics. Don't know if it will help keep the airfilter cleaner a bit longer. Hopefully so

Veemax..chop up that airbox!! part of the human condition... I want to get some more out of the old DR. One of the reasons I'm having it dynoed.

Tell me, some dog under general technical says he repacks the exhaust packing every 2000km..!! What?! And now he want to replace with steel wool...

I recently packed my zorst and not doing it again soon for sure!

That is a nice skidplate LeCap. Funds however is mimimal at the moment. So looking around to get some ideas. I might have a contact that can help me make one. Will try that - if not successful then I guess I'd have to fork out some dosh

If you want somethng nice with lekker attachment brackets that absorbs an impact and not just some shite that clamps flush onto the frame tubes damaging the paint and not preventing the tubes from getting smashed you'll spend a lot of time and probably not much less money.

I didn't compromise much when I designed my bash plate since they were intended as a once off for my own bikes. Everything else I've seen is made more or less cheaply :-\

How many are we talking about? If we can get an order of five together and someone who's going to drop off his bike for a day or three to measure & fit I'll make them :D

Hi all ....okay first things first ...bash plate.....very happy with my huge OEM aluminium one , which is as tough as hell and probably overkill. If enough guys are serious I can assist Le Cap with the loan of my DR as a template.

VR ... I'll need a long story to describe the mods on my new DR induction ... not really the place for it here either.

Now to the business of my Oldtimer DR airbox though ....

OK , remember my starting point is a new, rebored, bone stock 1st oversize enjin , a new, re-sleeved, rebuilt bone stock BST carb, and stock header, stock airfilter, stock jets, and Scorch exhaust the only non factory item in the breathing chain.

Well , I just ran an experimental ride with the airbox cover off. Interesting. Firstly a typical intake honk as expected. HOONNNKKKKK ! : )

Starting and warmup felt the same. No issues on idle circuit, as expected.

A nasty lean flat spot comes in at 4500 rpm. Some surging at part throttle across mid rpm. Yup, it's LEAN like this. It revs out to 7000rpm with ease , but I suspect it runs very lean in the full-bore mode ... no missing as such, but the power fades off after 6000rpm.

Bottom line : Yes , the stock airbox is proven to be restrictive , yes, there is lattitude for improved performance.

It's going to require a tenacious application of patience to get the needle height correct for a classic Stage 2 airbox mod , and to select the main jet will require a proper dyno run , and I prefer to have Before AND After results ... validate scientifically any claims to increases power !

Big question is now ....do I VROETEL , or do I leave my healthy, happy, factory stock DR well alone !???

Dammit if only I could get 2-3 deg advance on the ignition .... that will awake some growl from that big piston.

Mmmmm , I think I need a beer , have an awesome weekend guys.

i just made a bash plate for my XR500.
if you can get one made, do it, don't worry about the cost!
unless you can get material for free and have someone who can do proper, neat welding for you, it will work out more expensive making it yourself!
spent nearly R1300 on mine now (material was pricey... 4mm marine grade alu) and its still not completely finished.
still needs a few welds and some holes with the hole saw.

the template alone took a good few days to perfect, and then still had to make brackets to fit it... lots of time lying under the bike sussing it out! kak job!
unless you have serious connections (bins of scrap alu and a professional welder at your disposal), you'll sukkel to make a proper, functional bash plate for cheaper than lecaps offering.

Veemax, I understood the OEM bashplate is a bit flimsy...the one's me and WC have got on is stock and don't even cover the back end of the engine casing.

So, are you referring to the same bashplate we've got? Photo's perhaps?

Grego, I hear you. That's frieken crazy to pay that much for Al..I'll see what happens. thx

Yup, my bashplate does not even cover my sump assembly and it's really thin grade stuff , I need a seriaaaas one , but prob only after July when I get back from overseas.
In my eyes 1300 bucks is worth a hell of alot less than a big hole in a casing and an oil spill half my tank range from any civilisation  :mwink:

I've seen a 1400 Intruder and 650 'Strom both bust cases over rocks ... it aint pretty....engine hurri-kirri. Good night, nurse.

I'll take a pic of the thick and tenacious stock one and post it. Will absorb a meteor impact and shrug. Made in the day when men were men and BMW GS's were road bikes.

Excuse the dirty, working, DR , not washed yet since it's last outing. ( Note the Khaki and the dust don't quite match, darn )

Herewith bash plate detail ,  a la Suzook Factory.

Why is that bashplate of yours different to ours Veemax? I think Suzuki did make alternative bashplate-seems you got it. Here's mines and WC's. That R 1800 for LeCap's Bashplate WC, not R1300.

I might have a problem..Suzukie Edenvale. They gace me wrong front sprocket. Got it replaced..after trying to fit the chaim today it seems they gave me another wrong one....

Look at the photo, in neutral I spun the back wheel with chain on-the chain every now and then wants to climb off the front sprocket. I'm thinking the new DR's takes 525 sprockets and chain, the Pre-96 take 520 chain and sprockets. Would a 525 front sprocket do that - as seen in the picture?

If this is the wrong front sprocket again...

Best advice, go onto the Ron Ayers sight, check the microfische, get the part number

You up for a ride tomorrow Volroom, check out the planned rides, bring the pig if suzie aint ready.
