14,000 miles on mine. I don't know if it's a mileage or age thing, or just happens. I believe that my cam chain tensioner failed, the chain was barely stretched compared to a new one. I suggest changing both the chain and the tensioner though, maybe modifying the tensioner to manual adjustment.

Dont worry. If it aint broken, don't fix it . The timing chain will not lengthen all of a sudden, and you will hear it long before it could cause serious trouble. The NX250 engine is usually very silent in terms of mechanical noise - any rattling or clacking is due to lengthening of the timing chain and the incapability of the tensioner to deal with that. My Nixie started to rattle softly at about 70.000km – changing the tensioner did not help. At about 98.000km the rattling became so noisy that I tried a fix from this forum http://www.advrider.com/forums/showp...postcount=4993 and the rattling was gone. Of course I should change the timing chain, but this is by no means trivial and I wanted to finish the 100.000km with unopened engine (which a did ). So as long as no suspicious noises occur, I wouldn’t touch the engine.

My bike definitely didn't have a camchain issue. It's just something that has happened on some other bikes.

The engine that I'm pretty sure got destroyed yesterday had roughly 60'000km, assuming the previous owner had the speedo connected. I think it had 26'000km when I bought about 30 months ago.

I knew the valve-train was bodged and if it would have just held on for another week I would have had the new parts. It was a bit of a shame Oh well

Damn bike has a habit of only ever costing me money around Xmas.

Wait a minute – I always wondered about those unexplainable damages. Almost all Nixies just run like forever without any repairs at all, but a few seem to blow up every now and then. But now I noticed that the OEM chain does not have a master link – it’s an endless chain. This means that your chain must have been a replacement part and with the OEM chain something like that should not occur

Just out of curiosity: did you change the cam chain last Christmas ? And what exactly do you mean by the „valve-train was bodged”? As you wrote earlier, someone else already messed up your engine and then it’s a different story of course. Given that the engine wasn’t ruined by some good-for-nothing mechanics the valve train of the NX seems pretty durable.

Well, the bike was in Cambodia for much longer than myself. Some/Most of the mechanical work is shocking.

In this case two valves had been re-cut and re-seated by idiots.

I was going to replace everything before something like what happened yesterday happened, Murphy's law!

I've seen engines than run only because some inventive mechanic has used bits of coke cans and parts from other bikes and cars with no reference to a shop manual.

Now all my work is done by either myself or by a British mechanic friend.

No, last Xmas it got a chain and sprockets, a coil and a re-spray after a drunk idiot knocked it over with his car.

That was a drive chain that lost a master link. It was pretty worn out and was ready to be changed, waited too long!

Cam chain of course does not have a master link.

ok, then forget what I wrote - but I actually saw NX250 cam chains with master links at ebay

Fork Boot size

Hi - just picked up an NX250 today, and it needs fork boots. Does anyone know what size boots the bike takes?

Thanks.

I hate going through this thread. I want one for the wife every time. I know I asked before but cannot find the answer. Arthduro, where or how did you get your windscreen? There is finally a pristine nx in my town for sale with new works shock on it. White and blue whatever year that is. Thanks brother.

Hi, most boots are too long/wide but these fit perfectly http://www.ebay.com/itm/160919223797...887df5&vxp=mtr

They are a bit tight to assemble and you have to punch a few ventilation holes, but they are durable and they don't bleach.

I appreciate that. I checked those out, but I think I'll look for black boots; however now I know the size. My bike is blue, but I may paint it red like yours. Then I can pretend that it is a Cagiva Gran Canyon
