nx650 rally conversion - UPDATES P3-4

For updates: PAG 3 and 4



Hello,

I do not own an nx, but a close friend of mine does. We are planning a trip to Tunesia next year on our bikes. I have an xrv650 myself.

The dominator is a '90 RD02 with 27 000kms (20 000 miles) on the clock and will be adapted to rally/adv bike in the couple of months.

Plans so far:
- ktm LC4 adv 28L fuel tank
- ktm LC4 adv front fairing and lights
- africa twin xrv650 dashboard
- ktm LC4 adv luggage rack
- tkc80's
- new chain/sprocket set
- general maintenance + valve adjustment

Yesterday the tank arrived and it dit not fit quite as good as we had hoped. The right inner side hits the cilinder head (where the oil line goes in). The upper tank mounting does not correspond at all with the nx frame and if we want the tank to be leveled, it has to be lifted 3cm (1,5 inch) where it is bolted to the frame and meets the saddle). Also, the handlebar has to be raised at least 4cm (2 inches) to be safe, but this was already part of the plan.

The XRV650 front subframe fits plug and play. We did part of the wiring to get the indicator lights on the dash work.

Now we will just have to wait for the front fairing to see how everything will fit and what will have to be relocated/welded/adaptor plates made.


Some pictures:



13 vs 28ltrs





My major concern...









That's it for now.

Any advice, tips and tricks, critisism are welcome...

Cheers,

Hendrik (owner) and me, Thomas, co-builder

I have seen a couple of modded dominators with KTM ADV fairing and tank, there was even a guy here on Advrider with a really nice red one. Do a search, I am sure he can give you some pointers.

my thought is, with all the work and money your putting in, Why not just buy the KTM (or a better prepared bike) in the first place? especially if your already lost and you just got started. you don't want this thing falling apart in the dez....

good luck,

laramie

sometimes doing the irrational can be a lot of fun and money nor common sense are not a factor

I can guarantee that that tank and fairing and the other mods to his dominator will not equal the cost of a KTM....

I would say put a bar riser on, and keep going, that looks kickass!

Hi Laramie,

Thanks for your reply. You are right that buying a ktm in the same condition (or better) would be a better option, but here in Belgium (or france/germany if i want to travel a bit further away) a ktm that is in the same condition as this dominator was, would cost around 3000€. Sure my buddy could have bought a cheap (as in 2000€) ktm adv, but i think the rebuild of the engine would have cost him at least the same amount. I am not saying all cheap bikes are crap, but there is often a reason why a bike is sold for less money.

Now, in this case, the bike, tank, gauges, fairing, front lights have cost him less than 1 third of the price a very cheap ktm would go.

Also, the dominator engine is even more bulletproof than the ktm engine. And, parts or much easier to get hold off...

And, the most important, this is more fun ;). And if in the end we would not be confident the bike will make the trip, we wont...

Those are the reasons why we chose the go this way :).

Cheers :)

BTW, does anyone know if it would be a bad idea to heat the tank where it hits the engine with a heat gun (paint stripper) and bend it a bit inwards? It sounds bad, i know, but ... you never know :).

Should not be a problem to heat it, just don't use a sharp object to make the dent. A spoon would work well for example.

I did it on an acerbis tank years ago. Worked ok, never leaked.

Right, when I used to own an NX I bookmarked this post.

Cool project *thomas*, good luck!

At 6 to 8 litres less, you could fit an Acerbis tank straight on.
NX ones are available (in very short supply) and XR ones are a dime a dozen, they both allow more airflow around the engine too.
If it hasn't already got one - put an oil cooler on it. (XR 400 ones are the go)
Cheers

How's the fuel supposed to flow to the carb? Unless I miss my guess, you need a fuel pump inside the KTM tank in order to use the final ~6L of fuel.

You just use a simple vaccum operated external pump like the KTM does, they are pretty much bulletrproof and can be had for about €50 from Mikuni and other brands.

The older Ténérés from Yamaha also had a Mikuni pump. There's a tonne of 2nd hand ones on eBay to find!
