Thats exactly what I needed thank you!
need a photo of it installed?
Sure that would be great.
Yes, I am running a 525 chain, I had a new DID and it works fine.
You can see the clearance behind the lock plate as it shoulders against the cog offset. Note the washers behind the screws to keep the plate from bending. The oem Honda cog has a machined area that matches the shape of the locking plate which prevents the plate from bending. The OEM sprocket is a far better design but you take what you can get now that they are discontinued.
This discussion is very timely for me. I'm in the process of putting my 88 NX back together and installed the front sprocket yesterday. The bike only has 2900 miles on it and the sprockets looked good. When I took the front sprocket off the bike, the off-set was facing the engine side, the flat side was to the outside. I guess someone could have changed the sprocket over the years but given the bike's mileage and the condition it was in when I got it, I doubt sprocket and chain maintenance was high on their list of priorities. If it was changed it would not surprise me if it were installed backwards. If the sprocket is mounted off-set to the inside, there is no need for the washers and everything bolts down without a problem.
Now you have me thinking about which way is correct and how much diffrence it makes. I didn't pay much attention to the sprocket it's self, what are the marking on an original Honda Sprocket. I haven't put the chain on yet so it is easy enoigh to pull and check it or change it.
Your comments made me think back about my reasoning for this lock plate/washer solution, I have worked on a lot of bikes since I overhauled this NX and I forgot an important point.
You are exactly correct, flush side goes out but I have this cog reversed for a good reason. I failed to remember that I am NOT running a NX rear wheel but a XL600 wheel, I reversed the cog to get the chain lined up better.
The NX rear wheel that I had was badly corroded on the inside and with minor modifying the XL600 wheel works perfect and they can be found much easier that a NX rear wheel replacement.
I could have run the sprocket with the normal flat side out but I just didn't like the chain line angle, it was very minor but you know me.
At least this error on my part was found quickly, thanks.
Thanks for letting me know. This is the bike I plan to use on the TAT. I don't want a problem form someting as simple as a counter-sprocket.
I was just looking at this years acerbis plastics catalog (international version 2013) and found that they have the NX Dominator 23 liters tank listed on the plastic tanks page. All years, fromm '88 to '03.
I'm thinking its for the 650, since the cc is not indicated.
I thought some folks here might like to check it out.
anyone have a intake boot that they might want to sell?
That is the correct numbers for the us bikes. Looking through older catalogs it is also is the first year they have listed it in their catalog. Emailing them now. I'll let you know
Thought I'd take the bike out on the beach today before Spring comes and people are everywhere.
I got off the beach just as the dump trucks were pulling in. The pic of the water is of a baby seal stranded on the beach. I'm not sure why the camera makes it look so far away, but it was pretty close. If it were warmer I'd wade out to it. And for the record I thought the 'Soft Sand' sign was dumb, but the sand was REALLY soft. Very tough without a quad.
I have Tach problems, when at idle it reads about 800 rpms high, at road speeds ( 65-70mph ) the tach reads about 2,000 rpms too high. I have temporarily installed another NX speedo/tach assembly just to be satisfied that the problem is in this tach itself and it is. Other than the hi rpm reading everything else works as it should.
I have owned 4 NX650's and worked on a few more and this is the only problem of this kind that I have seen or heard of. Anyone else heard of this issue and is there a solution.
My tach's always been spot on, but my speedo broke again today on the way home! The cable is tight, I haven't pulled it apart but I bet its that gear again. That's twice in 4000 miles!
Just fitted my new Hepco and Backer rear rack and carrier today. Bought these from a dealer who had them laying around. Paid $140 for them, and bought the cases second hand (never used, price tag still on) for $260. Quite reasonable I think.
The indicator lights is an issue however. It's to tight a fit. I'll try to fit some LED lights I bought cheap on eBay in one of the two positions you see on the photos.
Anyone else who solved this in another way?
I took them off and cut them down. I like the large indicators instead of the LED ones, so I cut out the middle part where all the flex is. Then I glued the head onto the smaller main shaft. Now they're still big and visible, but they won't ever hit the ground or get in the way.
Did you get any information back about these tanks? I have one for the bike I'm building but I sure would like to have another for the next bike.
No, I've sent emails but no response. I may need to find an acerbis dealer to contact. I'll wait another day or so and see what happens
I finally had the time to pull off the front sprocket and investigate today. I noticed that you have mounted your sprocket with the "JT" logo facing outwards. I had mounted mine the other way, with the logo facing inwards. This allowed me to tighten the clip flush against the sprocket, without the need for washers. I have the washers ready and can flip the sprocket around, or should I just leave it how it is?
I had placed an order from cmsnl.com over in Europe for the panels in the "Astro Blue Metallic" original US color. I also had them throw in a front sprocket just for comparison to my current JT one. From the look and feel they are the exact same sprocket. But I measured the inside of the sprocket, and the OEM one is definitely thicker than the JT. Since I happen to have it apart, I'll put the OEM sprocket on. But I still would like to know if my turning the JT sprocket around, are any problems of countershaft wear averted?
Oh, you're running a different wheel. I really should start paying attention.:eek1
