    Did you replace it with a Honda CDI or a brand X CDI? There is a lot of junk electrical parts on the market these days.

    May be the carbon brushes in the starter motor or the starter motor itself. I had a similar problem. Good battery. Tried jumping at the solenoid, no movement , then its gotta be the starter motor. Polish off the copper contacts in a machine shop that knows how to it. That's how I did mine.

    Mas335,

    Thank you for quick answer. We know the dimensions? Maybe simpler to re-manufacture than order it from Honda... I can access machineri and 3D printing devices, but need to provide 3D model. (I can make 3D modell from a drawing :)

    Thank You all,

    These bikes are pretty reliable, they suffer from a few issues mostly well known at this point, CDI, A few issues related to the carb, missing vent hoses etc.
    Some rare electrical issues like pulse generators and the odd reg/rec failing. That said these are all fairly low price fixes and if one would like to upgrade the electrical system at the same time can actually prove beneficial.
    Stator from VT/NT/NTV/Hawk series bikes is a drop in replacement with the slightly longer bolts from those bikes to secure it.
    New Mosfet reg/rec and upgraded wiring to reg/rec and battery will allow the 300w+ to be utilised for other electrical needs.
    XR650L oil pump minimises the risk of top end trouble.
    Better front brakes are bolt on from the Brembo equipped 650 singles like SLR, FX etc and the larger disc from the same or an early Africa twin completes the job, then you have a bike which although 30 years old next year still handles well pulls well and returns good fuel economy while being very simple to work on and handsome to boot.

    Giga thanks for this group and Bounder!

    Should I ask for vertical sizes too? (the height of the plane with 3 holes, and the whole). I think they are important to keep the seat tight.

    Going back out to the shed now to refit mine so I don't have to fab one!
    Oh, I used a copper washer on top of mine to space it a little, it seems to bottom without the washer.

    Have made all of these upgrades myself minus the pump and can attest to their being worthwhile

    So I dropped my bike yesterday—very stupid, not worth recounting the story. I was at a stand-still, but when I picked the bike up I noticed quite a bit of oil on the ground. The bike had fallen to its left side. I couldn't really trace where the oil was coming from, but the bike exhibits no symptoms of a cracked case or anything like that. Soliciting theories...

    Talcum powder dusted will show any evidence of a leak, it may just have come out of the breather tube or airbox.

    Thanks for posting this, anybody in the US have one for sale? Someone was/is parting out a NX on fleabay. I reached out to them about this part, apparently they thought it was worthless and have no idea what they did with it. CMSNL probably has one for another non 88-89 that may be the same part, just haven't had the time to troll through their site plus it's a very pricey place to buy from due to shipping costs.

    Thanks again for posting the measurements, I made a suitable mount but it sits too low, and I did not take time to "key" the center hole so it swivels when trying to install the seat. I could probably fine tune it but I like nice fitting OEM parts.

    The real benefit with the oem part is the recessed bolt, this bolt head conflicts with installing the seat.

    I don't, I have owned these bikes before so I knew what part was missing, just didn't have dimensions. I keep checking out various parts at the hardware store to see what I can modify but no luck. I'll figure out some solution with these measurements, thanks again.

    My plan is to produce a CAD model and 3D printing the part from ABS (My son got a 3D printer as present from me for his mech. eng. degree ;) ). If it works, I will post the model. But I don't see free time for this now, so no promise when will be done.

    Hi!

    Here is the quick view of the first prototype. I hope we have time to print out and bolt-on at weekend. I expect some modifications.

    I was looking at a car damper this week and in the top was a dished washer looked fairly thick and about the right height.
    I'll see if I can get it off and have a measure up.

    I pulled the dished washer off the car shock absorber unit that I was looking at, it measures Ø50mm Hole in centre 10mm overall height 12.6mm
    A very small bit of filing would make the centre hole fit and the lip is 3mm in depth so remove that and you have a new seat holder.
    The washer is the part below the O ring on the left side of the picture.
