NX250 Thread -- official ADV owners manual

[polarized]

Thanks for the help guys. I already have springs from a crf230l in the fork which seems to be pretty decent, although it still dives under braking more then I would like.

I'll just have to try it without the fork brace first and see if I need to make up a new one.

was going to do a 'writeup' on how-to-service-carb, but haven't had time...

so, how about posting a few dozen photos of the NX250 carburetor ??

DEAL!
..<= dirty original carb
Accelerator pump diaphram & rod..
...<= bowl

jet holders/needle jet...
throttle adjuster...

Yeah, i know, the needle jets are TOTALLY clogged.....The NX ran a great deal better, performance-wise after this service...
This was the original 20yo carb with 45,000 miles..



This will forever be known as 'the carb post', #5837, page #390..

I am ready to start parting out the NX I recently got. It has CR85 front suspension and SV650 rear. No plastics except left side cover. Let me know if there is anything you can use.

If only you were somewhere closer, or if it were easy to deliver to argentina. I'd be buying you some parts.. Good luck..

San Diego isn't that far. Let's meet half way!

[fikse]

Are You a good swimmer? I would like to meet halfway for getting the front fork. To Norway please

Looks like the carb from my 200x,I also had to get a new one from DG for 130 bucks.it was so boogered and bogarted. If I had several 100 laying around Id grab the forks and supertrapp,being I live on the east coast shipping probably would cost me an arm an a leg

I sold the pipe, wheels and seat. I can weigh the forks and give you an idea for shipping, it probably won't be too much.

but I prefer to go with the 90/90-21 and without the fork brace – I never missed it, since once you get used to, you automatically compensate the twisting of the fork when braking hard. And I agree, it’s way too expensive to build a customized wheel since all front wheels from XL350/600, XR250 and from older XR600 (with 15mm axle) will fitt plugandplay – same 240mm brake disc. And some decent fork springs would always be a good idea, not only offroad

Hey Scrambler66, about that front wheel again... You're saying that a front wheel from a xr250 will fit plug&play?

I was going under the impression that wasn't possible.

So if I found one from lets say 1994 it should fit no problem? I would hate to drop a lot of cash on a whole wheel and not have it fit.

To my best knowledge, all XR250 had 240mm brake discs and 15mm front axles – the newer XR600 17mm, that’s why those would not fit plug and play. It might be that some newer XR250 had also the thicker axle (but I doubt it); you can check this with this link – it’s a list of all models with the 15mm front axle http://www.powersportsplus.com/parts...1-KF0-000.html


But I wouldn’t spend a lot of money, suitable wheels are not that expensive http://www.ebay.com/itm/1985-1987-HO...sories&vxp=mtr

Hello

you have never had a problem with brake rotor ?

I've cracked brake rotor 2 ?

[polarized]

Thanks again for the help Scrambler66. Seems like all xr250's use the same axle, just what I needed to know.

Anybody in the Riverside, California area willing to take a ride to JustGasTanks to see if any aftermarket tanks can be adapted to the NX. They seem to carry every brand. There has to be something that fits close enough to make work.

I have an NX250 CDI that failed a year or so ago. I opened it up and did a bit of soldering and got it going again, but it only lasted a month or so. I didn't remove all the old solder joints and re-solder them all so it probably had a few more fail points, also I am not very good at soldering.

I know there was someone on here who was repairing these, basically for free if you sent a CDI his way. What I would like to do is donate this one as a starting point, to get a pool of these going. That way if someone has a failed CDI they send it in and get the repaired one back right away.

Does anyone remember who was repairing these? Or does someone here want to step up to be the NX CDI guru?

Does anyone know the size of the flywheel puller? In the factory manual the universal Honda tool with 16mm, 18mm, 20mm and 22mm threads is recommended, without bothering to mention which thread actually fits the NX250 flywheel
