    I put the fork leg in a vice with some rag around it and pulled the inner slider in and out so the bottom of the slider hits against the seal, I started with taps but it took hard yanks to break the seals loose and get them out, I had to be fairly brutal, who-ever put them in didn't put any grease around them... also, make sure you remove the circlip that sits above the oil seal, under the dust seal....

    I had the same issue getting the piston to go back in... I put the old piston side pad back in and squeezed with a F-clamp while cracking the bleed nipple open, .... Don't try pushing the piston back in by putting force straight on the face of the piston, for heat insulation they have a thin metal covered fiberglass disk on the end of the piston that could easily be damaged...

    I always had a fairly spongy front brake... I suspect it was due to the old rubber brake hose expanding... If your brake overhaul doesn't fix the issue it might be worth trying a braided brake hose...

    Good Luck :)

    So the valve adjustment increased mileage by about 1 mpg. I got 35 for the last 70 miles. I threw in the 165 main, an the engine ran down here (5000') like it does at 8000' with the 155. I think I'll try a 150 main. Also, what is the function of mixing screw, I can't seem to notice what it does when I adjust it. Also, my carb kit came with two o-rings one for the tip of mixing screw near the spring and another is supposed to go somewhere on shaft according to the parts diagram but I can't figure out where, it is also a larger diameter. There was no existing one to compare to. Any recommendations on a high flow air filter? Can anyone else think why my mileage is so bad? I can incorrect jetting really throw off mileage by 15mpg?

    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!!

    <a href="http://www.flickr.com/photos/61664897@N04/8657801848/" title="Dominator is kaput!!! by MAX ATTAX, on Flickr"><img src="http://farm9.staticflickr.com/8113/8657801848_79d45b25fb_c.jpg" width="800" height="600" alt="Dominator is kaput!!!"></a>


    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!
    :D

    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:
