    I think I payed $166 for my cdi a few months back at servicehonda. Worth every penny.

    Or I could make you a low-ball offer on yours...

    Now you see the inspiration of my screen name...

    Be careful, SuperMoto/Motard is next:D

    And you don't want to know what that feels like. B/c it will get more addictive than drugs, and be harder to quit... This bike is so much fun just to flick.


    And for an off road rig... I like the looks of the KTM 250 SX/XC-F VARY much.

    30-40 horsepower and more aftermarket than you can shake a stick at...

    Then you can go "sportsmans" with it and get two sets of wheels for it. Off and on...

    The 13,000 redline is just dreamy to me... :lol3

    Though something in a 450-520 would have better low-end grunt...

    :D I wish it looked like this today :-/

    Well, its been a long while since I've posted here and I sold the white NX250 I had last. Just bought the bike Trevhead mentioned a few pages ago. Blue 89 with now 2275 mi. Bought it without seeing it first (except pics), so I hope it lives up to description and pics. He says it looks almost like it was stored in a crate the whole time...as close to new as you can get. We'll see. Paid $1250 and $50 gas for the guy to meet me in upstate PA and save me about 2 hrs driving. Will be meeting him Thurs.

    Without reading the last hundred pages here and finding the other thread.....has anyone come up with good supermoto wheel/swingarm/forks ideas yet that dont require a CNC milling machine in your home shop? :D

    On an odd note......the bike wouldnt start for him when he bought it last yr, and he said the dealer sourced a suzuki/aftermarket cdi unit for it VERY inexpensively. He doesnt remember specifics, and I dont know if there'll be a receipt with the paperwork, but I'm very curious.

    Heres a pic of the bike.

    that CDI unit will have a part number stamped right on it
    be sure to tell us so we can research it

    looks like a really clean bike from that photo
    hope it turns out like that

    keep us posted

    Boy am I thankful I found this great resource:clap

    Irish Expatriate currently residing in Phnom Penh, Cambodia here.

    I picked this baby up two months back for $950:

    [​IMG]

    And promptly blew out the back shock and spent $116 on a rebuilt one:cry

    Had 1k of trouble free driving and then, two days after driving through a deep flood for maybe a mile, the back wheel bearing went.

    Plus it developed an erratic idle.

    So, given that I face some of the most "challenging" road conditions in the world (insane might be a better word) , I stripped her down fully, changed the camchain, valves, front brake disk, battery, rear tyre, chain & sprocket, filters, plug, plastic welded dodgy fairing bits.

    I also had the frame blasted and resprayed, all fairing and the tank sprayed, new stickers, cleaned out the headlamps, forks and bars re-chromed, every nut and bolt exchanged for new chrome/stainless steel, jobbies, wheels re-painted, engine repainted, new cables, new piping, exhaust polished and carb rebuilt and rejetted (though this is not right yet, have questions about this).

    Jacl thats a beautiful bike. You could almost call it new. Why they did the nice wheels and rear disc on the ax and not the nx I'll never understand. Also looks like the ax came with a stainless header?

    Thanks people, I'm very happy with it.

    If I visit another country in the next few months I might pick up an SV rear shock and plan on doing something to firm up the fronts a but too, as roads here are damn bad and even the road I live on is not paved.

    Since the rebuild I have had a very occasional mid-range stutter, where the engine seems to hesitate briefly before delivering power. Most commonly happens when going from 3rd gear to fourth or back down and getting on the throttle post gear change.

    Have sent it to a decent mechanic twice in two weeks to get this sorted and it's still there. Sometimes this can be dangerous - if you are overtaking without much of a window for power loss, in particular.

    I wonder if the weather here could be a factor as half the year it's pushing 40c and the other half is always between 28-35c - with huge humidity.

    Also, helmet cams are not available here, so I have designed a mount for my bars to hold a digital camera that I must get run up - anybody done the same?

    I'm looking at making this:

    One alteration being a flange on both sides instead of the hinge shown on the left side.

    It has 28.5k on the clock, was 26.5 when I bought it.

    Anybody know how I can find out the year of manufacture? They are not real big on tracking details like that here in Cambodia:huh

    Aronhk -I don't know that the CDI wouldn't work, although the AX-1 has a few extra ponies (i think?) so that may make a difference.

    Not sure about all the restriction claims of that ebay CDI.
    I don't think any of the NX in the states and Canada were speed or rev restricted. I know mine has now gone 145 and I also had it at the red line a few times and I think anything more would just plain blow it up.

    The AX may have been restricted in some markets but I have no real info on this. I did get a Sun Systems unit from Japan a while back and it has really worked well from what I can tell.

    AX did come with a stainless header indeed.

    Jackl have you considered starting with a RAM mount for your camera mount would be a bit more flexible and provide more vibration protection.

    Well, problem solved. Not the CDI, i don't know the name in english, but its some kind of voltage collector/gatherer from the alternator, one little piece that was damaged, that costs only 26euro. That was why my rpm's while on iddle were unstable.

    Hope this will help people who had the same "#$=! problems that i had to save some money!

    ArthDuro....I think you are right that they were not mph or rev limited. I wonder about timing. Obviously they do limit that as excessive timing can cause overheating, but sometimes the factory went overboard there.

    I have been corrected I now know that some US models are in fact rev limited around 10,000 but I am not sure if that is just the cali models or not.
    Top speed limiter is still a question.

    Mine has neither, but I do have an aftermarket CDI.

    I doubt there is a speed limiter of any kind, as that would imply a tie in with the speedometer. These things arent that complex...lol. As for a rev limiter...dont think I'd want to spin them above 10,000 rpm anyway.

    Which leaves us with the idea of a modified/improved timing curve. I wonder...

    I'll have to see what cdi is in this new bike of mine...the owner mentioned it being an aftermarket suzuki item.

    Those RAM mounts do look good. I have issues though with shipping costs to Cambodia and the fact that about 50% of mail does not get here.

    Might see if they are available OTC in Thailand as I will be going there to buy Duty Free Whiskey for my bar in a month or so:freaky

    If not, I know I can have the mount design of mine ran up and chromed for under $10.

    My first real dual sport was an NX250. I abused that poor bike but except for the CDI issue it never let me down. The motor was awesome. In a funny way I miss the way that plastic smelled...you NX owners know what I'm talking about.

    Me circa 1992
