Budget Nx 650 Dominator adventure bike build

Hi all, I know there's a few people out there who,for whatever reason are unable to spend alot of cash on building up an adventure bike.
So I'm going to share my cheapskate ideas with you in this thread so just ask if there's anything that I'm not clear on.
What I was trying t achieve was an adv bike that was lighter than my RD03 Africa Twin that I can use for the more challenging rides and able to be carried on a rack on the back of our converted bus/camper, It also has to be capable of doing 2 up rides and all on a next to zero budget.
The '88 Dommie worked out perfect and weighed in at about 160kg when I had finished it.
Pricewise it cost about NZ $2500 all up including the purchase price and the $350 I spent on the build....thrifty aye.

This is a pic of the beast as purchased (thanks XF650 for delivering it)


The bike I bought had a completely rooted shock and exhaust (both of which I was going to biff anyway) and the carb had various issues.
The motor was sweet though so all I did to that was reset the valve clearances, change oil and filter and fit an iridium plug.
I already had this WP front end off my buggered LC4 400 and the adaption was relatively straight forward after about a week of head scratching.

NX tripples


KTM ones

I learned to use my neighbours lathe whilst turning down the KTM stem to fit a new set of NX spec taper rollers and also turned up a bush with a split in it for the top tripple.





There is a more elegant explanation for this here http://www.xrv.org.uk/forums/africa-...onversion.html
Or you can actually buy a kit here http://www.ruggedroads.co.uk/shop/ar...6aid%3D7016%26 if you have some $$'s (AT is the same as NX and probably the Transalp and XR's as far as I know)
While on the lathe I spotted a piece of that tough nylony plastic conveyor roller stuff and turned up some bar risers....plastic bar risers?? might be a world first I rekon. Just had to buy a couple of longer SS allen bolts.





Welded on a new steering stop but didnt bother with the steering lock as I didnt want to get too much heat on the frame with my basic welding equipment.

The shock I built up from a mix of an XR200 and XR250 (thanks pablo83 http://www.thumpertalk.com/forum/sho...6&postcount=55 )
and lengthened it a bit with that nut thing and the drilled out bit of a bolt I found in my shed full of junk. (its a bit long now, will shorten it by about 5mm on mk2) Used the original NX spring and unfortunately as I live way out in the sticks I filled it with used oil and pumped the gas cannister up with a bike pump





It works well enough to proceed now with mk2 version ($20 trademe XR250 shock) which I will make a bit shorter this time and mabe even shout it new oil, a seal kit and get it gassed up.
The carb got Daves carb mods http://www.4strokes.com/tech/honda/xr650lcarbmods/ which involved drilling these holes in the slide out a bit, I jetted it to 55 and 158 (will probly go a bit bigger on the slow jet but it's actually going real well) put a washer under the needle, replaced those silly cross head screws with some SS allen screws, gooed up the big crack in the inlet rubber and put a return cable on the throttle as it previously had none. and chopped the snorkle off (I actually ended up cutting more than the pic here shows)







Oh and gave this tank strainer a bit of a clean


Snorkle



For the exhaust I used a $40 ZX10 can, I think the cat has been gutted out of it and it sounds awesome, but not too loud. I just bodged this together with bits and pieces, clamps and shit as I havent the technology to do any thin metal welding but it actually works real well so I'll work towards getting someone to make up a SS link pipe at some stage. It also weighs less than one of the original cans.



A bit of angle grinder milling on this bracket

Now the bit you've all been waiting for.... how do you go for a decent ride if your tank only holds 13 litres (if that) ?
There was a run of plastic tanks made years ago but not available any more and besides I like the feel of the original tank for riding, nice and compact.
I found a 5 litre plastic container in the shed (actually holds 6 full to the brim) right price and it came in my colour
There was a piece of alloy plate (in the same shed) that I'd cut out of a bulkhead in my boat so with a bit of hacking and bending I came up with this.









It keeps the weight low, doesnt get in the way, weighs bugger all and now I can get 300km....maybe.
Its quick to whip of and on for refueling and I've tried it and get about 100km from the 6 litres.

I wanted to reduce the wind on my chest so splashed out on a bit of plastic and made up a screen.
I'd burnt out my heat gun by nozzling it down to melt plastic with ...so used a little gas torch to heat this, works ok too if you dont get too close, then it starts bubbling up. Had to provide for the Barkbusters by bulging it out on the sides as they are quite bulky.







There was a little bit of plastic left over so I used some sticky velcro and made a headlight protector, can easily take it off to improve the light at night, which by the way I invested in a '+90' H4 bulb for it and its good ! 90% more light for the same wattage....cant go past that.





So here she is in all her glory, I've been out and about the local neighborhood sorting the suspension and so far I'm well impressed with myself ,even been for a two up ride.

Nice! Glad I could see the build up, finally.

I did enjoy my '95 Domi. Ohlins shock, Acerbis 21L tank; a grunty, fun adv machine. Only sold it because it led me down the path to true off-road riding, and it wasn't such a good match for that arena.

PS the bottle of 'turps' with the headlight protector is a bit of a step down from the homebrew, izit?

Great effort! I used to lust after a Dominator when I was 14 If I had a bigger shed I would be very tempted by some of the cheapys like that.

It could do with some red stickering on the lower section of the screen to retain the original lines though I reckon.

Cheers
Clint

My homebrew doesnt taste like turps.....I've tried it out on heaps of people and they all say it tastes waaay better than turps.
Red stickering Clint, now thats a good idea. I was going to make the screen out of a dark tint to hide all that untidyness but apparently the motor cycle screen stuff only comes in clear.
