    I'm looking for a new chain for the NX. The last one I bought only lasted about 5,000 miles. What can anyone recommend?

    Dominators and all big singles eat chains and sprockets as a rule.
    Try a D.I.D x ring and get a chain oiler like a scottoiler or cheaper alternative.

    I am looking for a shock on a budget, is there any onther model shock that fits the dommie? Africa twin etc? Anything with adjustment?

    Can the dominator shock be rebuilt?
    Pretty sure mine is dead, very badly corroded and feels like its stepping out when getting on the power at the apex.

    I'm not looking to spend a fortune.

    DID X-Ring... I went for the heavy duty "DID 520ZVM2" because Rocky Mountain ATV had them cheap at the time, not sure they still make them though... I did about 10,000 miles on it before I bought the Tenere and put the Dominator in storage, and it was still as good as new, I didn't have to adjusted it once after installation...

    Things you probably already know:
    It seems better to run the chain a little loose rather than a little tight, to avoid stretching...

    Install a new chain with new sprockets, and since front sprockets are cheap it's worth changing it a couple of times over the life of the chain... (i.e. buy 2 (or 3) fronts, once it's showing some wear swap it for a new one, when that one is showing decent wear put the original one back on to finish it off)

    Some people prefer not to lube, but I like to give the chain a good squirt before each long day ride, or each morning on multi-day trips....

    Not really, have a search, early XR200/250 shocks with no remote reservoir.
    You could call VM-tek in Kinsale and ask them if they can rebuild yours? The non-rebuildable units can be rebuilt with care.
    Wilbers are 399 Hagon are 300 stg, Wilbers are a better shock with a 46mm piston and better build quality.

    I learned some bad news yesterday... took my dommie for a service and the mechanic had a look at the engine.... the valve lifters are completely ko'd!!

    This happened because the engine was starved of oil and so the cam lobes/lifters wear out quite quickly. IT was making a slight clicking noise at idle, which i thought was worth investigating.

    I'm now in search of a new head for this motor, need it back on the road asap!

    Cheers for the info bounder, any idea how much a rebuild is?
    That's good to know about the Xr shock.
    Romor has it the xl600 may fit (google info) but not 100% on what years.
    Unfortunately with 3 bikes I can only consider budget shocks for the dommie ATM.

    Would a XR650L head work?

    uhmm not sure,

    I've heard that the xr600 head works, so i presume the xr650 must be even better ? (since its the same 644cc capacity?)

    Not looking good for me, i'm supposed to take it around the balkans next week and right now, the dommie is in bits...:norton

    I have a good XL600 shock but not sure it fits.
    I'll measure it and see what length it is, what length is yours?

    I have a montreal trip coming up in a few weeks, and as a precaution I was going to replace the pulse generator. I've heard about it failing, but is it common? Mine is original - I've never even removed the case cover.

    Well, it looks like the oil pump was a bit damaged too- the previous owner did not change the oil too frequently and i think some of the pipes were blocked- on the these engines, the biggest weakness is the thin oil pipes, which can get clogged very easily.

    I guess my cams must have been screaming in vain (grease me baby , grease me):clap

    It doesn't look like the oil starvation was too bad, the center bearing isn't chewed up... How bad are the cam lobes?

    This thread has a lot of good info, and some guys that know these engines inside-out:

    Goodluck with it :)

    Thanks pal!! I'm trying to stay calm and patient but i'm really struggling to find bits for the dommie in good condition!!!

    Well, here's brief update on things:

    The cam + head was taken off yesterday, and here's the extent of the wear
    <a href="http://www.flickr.com/photos/61664897@N04/8666548676/" title="nx650 head by MAX ATTAX, on Flickr"><img src="http://farm9.staticflickr.com/8260/8666548676_f35cbb79e8_c.jpg" width="800" height="534" alt="nx650 head"></a>
    The cam lobes= notice the scoring in the middle :cry

    the pushrods

    The valves (crunchy, but ok)

    Overall i've been told that the head + cam + pushrods need re-doing/changing. I don't actually know if these can be machined but i hope this is the case.....i'd really like to keep the engine original and get it going again, since the rest of that motor is good..
    On another note i don't know what i'll be riding to budapest next week:lol3

    Sorry Bounder only got a chance to measure the shock today.

    It's 13.5 inch or approx 34cm (measures in the bike on a trailey stand.)
    Showa my2601 is written on it.

    In interested in the xl shock if it fits.
    Thanks, John.

    The cam and ROCKERS are shot. Easy to find.

    And NO you won't be riding your Domi next week.

    Hi guys, long time lurker, first time poster.

    I'm in Tanzania, looking for a bike (just sold my XL250), and a guy said he had a Dominator for sale and sent me this pic:
    [​IMG]

    :scratch What do you make of it? It looks like a Domi engine/frame, but all the fairing's gone, front guard, and I'm not sure what's going on with the exhaust. Any ideas? Looks closer to an XR650L, but the plastics are all wrong, and I'm pretty sure it's a Domi frame. The seat colour makes me want to puke.... :puke1

    Cheers.
    (looking forward to getting back into riding here.... so many good rides!!)

    Thats an RD02 Dommie with no fairing and a trail headlight, and the sidecovers have been either made up or adapted from something else.
    Rear guard looks standard and there is probably a single exhaust fitted.
    Everything else looks standard, wheels and forks seat etc.
