Nx250
 
Been lurk'in in the shadows for a bit.
Just came across a beat down 88 model
on the cheap.Plan on using it as a commuter
and fire road eater this season.
A little here and there should sort out the
niggles.
A quick carb cleaning, fresh fuel, and air in the tires
and I had a pretty good runner.
More to come later as it is missing the front fairing
and the instruments.
This will give me the excuse to build a custom bike
how I see fit.
A blessing in desguise.
Here's a pic as I got it.

jamin_mathis 03-17-2008 08:22 PM

Good idea VC we NX riders need a place like this to find useful info with out all the other stuff.

Getting that carb in and out was anything but quick for me, the whole time I was thinking "I must be doing something wrong this shouldn't be this hard to pull" I guess I was doing something wrong but after removing almost all the plastic, the tank, the air filter box and the seat about 3 hours later it was done and running great.

Jeff@TheQuadShop 03-18-2008 05:50 AM

Here is what I've found for a better tire solution so far....

I finally found another front tire that may work and be a bit more aggressive. Its the Mefo MFE99, its a 3.50-19 and the stock Trailwing is 3.8-19.
http://www.mefotyres.com/mefo/Reifen...FE_99F%2Bh.gif

The Dunlop K460 comes in the correct (close) size as well...
http://opony.webwweb.pl/img/1155/115533462.jpg

Here is another option for the rear..
Duro HF904
http://www.denniskirk.com/denniskirk...0pix/hf904.jpg

Jeff@TheQuadShop 03-18-2008 05:53 AM

I swapped out my 16" rear wheel for a 17" from a 87 XL250. This opens up a whole new world to rear tire options.
I'll be going with the Kenda K270, this is a great long lasting tire that served me well on my TAT trip last year...

Yea, there are certainly easier carbs to get in and out.
But from my experiance the CRF 450 is way harder in my opinion.
I do like the pumper feature for a late 80's bike is pretty nice.
But when in the carb I tend to take my time so I don't have to
tear into it again.Have fun with your NX.
NX's RULE!

Jeff@TheQuadShop 03-19-2008 07:06 AM

Just for refrence, all these models use the same rear sprocket as the NX250. This may help in searcing for ones with a different tooth count.

FAQs for NX250 AX1 250 Dominator
 
Items still needing identified or resolved:


Chain slider - is there an aftermarket alternative?*'81 XR250R? not proven
a flexible cutting board from Walmart has been successfully used in a pinch to protect swingarm, using RTV silicone gasket to affix the flexible cutting board(shaped like OEM slider) to swingarm.

Front sprocket cross-reference -what other model will fit?
rear sprocket: See Post #12, right above this post your are reading~thx Jeff@QuadShop

regulators/rectifiers -- what other HOndas fit?

If you can answer the above questions, please reply in the thread with your findings, and/or send me a PM so i can update and add it here, thanks!
If you have any question you want added, please pm and it will be

FAQs for the Honda NX250 AX-1 250 Dominator
***********************************************



I need a longer clutch cable for high bar risers, wider handlebars, longer fork tubes, or taller handlebars?
1984 Kawasaki GT550 (550GT)
Kawasaki OEM#: 54011-1164 ~thank you Scrambler66+ArthDuro

Can I use a different CDI than the factory Honda part?
link CurtW found aftermarket CDI on Ebay link

Are there any other footpegs that will fit my stock NX peg carrier?
CRF50/XR50 pegs work without modifications~ArthDuro

The headlight won't work, but the other lights are fine, and all the fuses are fine....etc... why? What is wrong with my headlight?

There is a small spring in the 'start' button for the engine, built into the right hand control. This spring will get dirty, or become loose and break the circuit for the headlamp illumination.
carefully, disassemble the right hand control, and clean the contacts and the spring.


My NX250 keeps falling over, to the right side of the bike? wth?
Kickstand Mod

Is there a K&N style air filter option for the NX250?
http://www.knfilters.com/images/s/MG-0001.jpg
The OEM filter measures just under 4"x6" inches(add mm here VC!)

K&N makes Part #MG-0001 for the MotoGuzzi V1000 Lemans/California models.
It measures:Height: 1.22 in (31 mm)Outside Length: 5.984 in (152 mm)Outside Width: 4.449 in (113 mm)
. Some work is required, mainly cutting and filing. Then an adhesive is used to glue the OEM rubber frame to the K&N filter's body.
33-2263 is close, and is being experimented with.

What size tire or tube should i get for my 19" front rim, or 16"/17" rear rim?
here's a nice tube size chart, and a nice tire conversion chart thx-Rvn Ranger

What's my battery?

YTX7L-BS
(same as Honda Rebel, Ninja 250) Ebay is a good source for inexpensive ones...
Try Here or here or here
For suggested starting prices, browse from there...
Also, look for the newer Gel type batteries(add notes here VC!)
Another option is to find a battery with the same physical size, but more 'plates' are in the battery.
(Put example here VC!)

My NX250 fell over to the right, i need a front brake lever? Anything cheaper than stock?

Parts Unlimited has # 44-1001 Polished brake lever Honda for $5.95, also in black

My bike needs fork boots! Who makes some?
Daystar Fork boots Part# F00234
There are others, the boots need to fit 37mm forks, with x amount of travel.

Why won't my bike spark?
Why doesn't it crank, or even hit a lick? Sometimes my bike misses, runs like crap and cuts off, then it won't start. My tachometer reads funny sometimes, or the tachometer doesn't move when the bike will turn over, but not start.

Check your CDI. If it starts with KW3....its the old 80s CDI
there was a factory issue with the CDI in the late 80s.
They will all fail sometime. Replace with a known good cdi, before you look for other component failures.
KW3H is the new part, updated sequence code....
should be printed on the CDI plug area..

There is a good video of a functional CDI p#22.
Video of good CDI tach view here
CDI discussion on abouts page #22 of this thread.


My bike is hard to start when it's cold?( I use choke a mighty long time, or else the engine shuts off when it's cold. Also, it doesn't quite have the normal power i remember)

It needs intake valves adjusted (do all 4, shim under buckets)
Check here for the short list of symptoms.
the carb's dirty

Is there a carb rebuild kit?

Keyster KH-0858N is the kit number.
Try Googling the part number, "NX250 Carb rebuild kit", or looking on Ebay.
This is just a suggestion/illustration...it's pricey! on that site.

What parts fit my bike?
The NX250 doesn't 'share' parts with very many US machines. Internationally, the NX250, AX1, XL250 Degree use the same engine, share frames(though some are square rails, and some are round frame rails)
HERE is a list of nearly all parts for the NX 250....Thx RabidSquirrel

My shifter is 'loose'. Can i get an aftermarket shifter? What model should i use to crossreference?
The (84-85) XR200R, XR250R, (84-87)XL250R has the exact same shifter as the NX250.
The (84-99) XL600R, and XR600R will also fit!, thanks Jeff!theQuadShop.
A little bird told us the Yamaha TTR250 (99-06) will fit, but lengthwise?-VC

Can I get those funny rubber 'wellnuts', they are like threaded rubber sleeves that hold my cowls to each other and to the bike?
Here or
link <------
http://www.desmoparts.com/products/p...tm/m5-wellnuts

What is a good tire for my bike?
Did you read this page?:lol3 the one you are looking at to see these words? Tire discussion is on this page and the next few after this one.
Also around post #850, it's revisited a bit.

Where can i get the 17" rear wheel for swapping onto the NX250?
84-87 XL250R, 85-86 XL350R

Where can i get a cheap jack for my NX250? Something just to grease the chain, or check swingarm bearings and the like...maybe like a light duty lift/jack?

try Here

Where can i find the cheapest parts OEM online?
