    Howdi!

    I just dismantled the valves and did a free-length check. The inner springs are all too short while the outer springs are all OK. Should they not wear more evenly? And is it OK just to change the inner springs?

    Hello all.

    This is my first post.

    Just want to introduce myself and my bike.

    I’m from Portugal and my hobby is definitely motorcycles and its mechanics.

    Since I first bought a chinese quad (piece of junk), I got the taste for it and decided to go 2 wheels.

    Of course Long Way Down and Long Way Round helped to get the taste.

    Then I have had a Yamaha XTZ 750 Super Teneré (to big for me), a Suzuki Intruder VL 1500 (still have), a Yamaha TW 125 (love it but lacks power) and recently (February 2013), i bought my dominator.

    I always try to put them better then when they come into my hand. The closest to the original as I can.

    In my dominator I have been doing some corrections to it. The previous owner had change it but i didn't like the look of it. Luckily he had all the parts so i just had to put it back together.

    Not without first disassemble all the bike, :evil

    Here is a photo of her actual state.

    I will post more details and difficulties I found when I put it back together.

    I don’t have much experience but fell free to ask whatever you want about it.

    Sorry for bad English if it’s the case.

    Cheers

    Welcome! Charles Phillipe.
    Nice dominator you have there.
    Portugal is a perfect place for the dominator!
    You have some great dirt tracks by the coast and up the mountains .
    What part of Portugal do you live in?
    Fantastic country!

    Hope you enjoy your stay here!:1drink

    Thank you Skapegoat. :D

    Portugal has indeed great dirt tracks with lots of sand. In the winter mud is all over the place. :D

    I live near Lisbon, on the south side of the river Tejo.

    I’m planning a trip with a friend of mine to south of Portugal, more exactly to Sagres. It’s supposed to take only a weekend, but we wanted to be 100% offroad. However before that I have to get some offroad tires. My first experience with my actual tires on sand was not very promising. :D

    I believe Ireland has very good conditions to ride as well.

    Cheers.

    I have been to Sagres and I have drank lots of Sagees beer too!
    Sounds like a great trip but there are some great roads and trails on the south coast too.

    With off road Tyres the dominator will be perfect for that trip.

    Ireland is good for touring but there are not many gravel roads.
    Most of the roads are paved and some have lots of pot holes.

    To find gravel roads you have to head for the mountains into forests which your not really supposed to enter.

    Throw up some more pictures of. Your dominator!
    What year is that?

    Hi guys!

    So i just broke of the skew attaching one the exhaust pipes to the cylinder :baldy

    I'm guessing I'll have to open the engine to replace this.
    Is this the case?
    Also, are there any other things i can do if i have to open it? I'm thinking replacing gaskets and such.

    Cheers!

    That will come out with a bit of care.
    You may need to drill it out with progressively larger drill bits then use some penetrating oil, acetone and ATF fluid is a good mix.
    Then try and gently remove it with an extractor, you may also need heat as well.
    If you aren't confident then ask a good engineer to remove it in place.
    Its a simple job with the potential to become a very big job.

    I'm guessing you mean the exhaust stud on the head. If there is any sticking out, try welding (have someone weld) a nut on the stud. Sometimes the heat will break it loose. If you have to drill it out, finding the center with the first hole is important. Go slow with larger drills and don't break off the tap. It is really hard and brittle. If all else fails, remove the head and take it to a machine shop that has an electric arc type stud/bolt remover. Worst case, drill out the stud, weld up the hole, drill and tap.

    Ooooh yeah. Remove the exhaust, screw a nut on the broken part. Have someone weld (stick, mig, tig) the center of the nut to the broken stud and while it's still hot unscrew the stud carefully. Works most of the time. This was a common problem on old air cooled VWs. They made a special stepped nut for a quick fix. You had to drill the hole in the exhaust flange bigger for the nut to reach through, but they saved a lot of heads.

    Finally got the Brembo/320mm disc sorted. Hot as hell today for Ireland, around 29degs here in the shade.
    Brakes are strong compared to the Nissins I had before and very progressive feel.
    The Disc is the same as the XRL kit SM6010C but the bracket that comes with the kit doesn't fit the NX.
    Hose mounting is a bit shonky, none of the braided hoses I had were the right length or fittings, I had to use a NOS RMX 250 one that I had lying around which was a bit long.

    Haven't ridden much this summer, and last had my '88 NX out for a spin a couple of weeks ago. I was going to take it out the other day - after the rain stopped, finally - but it wouldn't start. I pulled the plug wire to check for a spark and nothing. It had been running just fine last time out, now, zero. I never use the kill switch, but the thought occured to me, could I have bumped it into the "off" positon? But when I look at it I'm not sure which is the "off" and which is "Run" !
    I believe the "Run" position is with the Run side depressed, Off side up.

    But if that is the case, then why no spark?

    Have you checked the clutch cut-out?
    Is there a side stand cut-out?
    The switch is on the way you have it.
    Off is the top button depressed.

    No side stand cut-out - normally start it leaning on the side stand - and I normally pull in the Clutch when starting. BTW, lights, etc work ok.

    Mine is an '88, . It won't start unless it's in neutral, even with the clutch pulled.

    Also there are TWO switches that need to be in the correct position. Along with the key turned on. And in Neutral.

    Check the clutch switch.
    There is a small unit beside the clutch with two connectors.
    Make sure both connectors are plugged in if so chase those two wires looking for a break.

    It should start in any gear with the clutch pulled in.

    Thats a super clean NX650, it looks almost showroom.
    Mine used to look a bit like that but the cases are a bit furry now.
