NTV 650 Gear-cluster & selectors wanted

[ED-CASE]

Hi, from Ed in Plymouth
My M-reg. NTV 650 jumps out of 2nd, most often in an up-change
Does anyone have a spare gear-cluster, preferably with selectors?
All the best

Not gonna do you much good I'm afraid....
Search on the forum and you'll find it's more of a design flaw then anything.
Most people (including me) learn how to change gears differently on an NTV...

Replacing them might fix the problem temporarily but don't be surprised if it comes back....

Once you have mastered the new way of changing you won't notice any more.
When changing up make sure you select the gear firmly and keep your foot under it while you release the clutch.
Also, it helps not to try to do it too quickly or in high revs.
Mind you....I can still do a nice dragrace and not look foolish and even beat the occasional other bike
Keep all this in mind and the gearbox will probably outlast the owner

I agree with Buzzin, for the time and expense involved, you're not likely to achieve anything more than frustration.

It's a poor design and unusual for Honda, but most people learn to adapt quite quickly.

Mine will do that if I change quickly into second.

Options.
1. Don't accelerate as hard. (the one I use) Then after a revolution twist and grin.

2. Hold your foot up (the method my brother used to use when the bike was his) to old it initially in second.

3. Jaz on the forum does not even have second gear and goes straight for third.

4. Try and fix it. (can't say this gets my vote either) A replacement engine seems to have a greater success rate.

All the best for the project.

Hi, guys, I do appreciate the advice
Part of the problem is that I'm stubborn
Another part of the problem is I'm an irrepressible optimist
Also I suspect there is more damage in the selector mechanism than I have fixed so far
HEALTH WARNING:-
TERMINAL BOREDOM HAZARD APPROACHING
I welded two cracks in the clutch-side selector mechanism AND I have pix to prove it!.......
Bear in mind my NTV was a virtual giveaway from a friendly local motorcycle breaker - and -
It was obvious why it had been scrapped! (see what I mean about stubborn/madly optimistic?)
I reckon the nearside impact which mangled the gear-lever caused some internal over-strains as well, so.......
I'm hoping that acquiring a second gear-cluster will allow me to improve two things:
Firstly I suspect the bike is actually VERY high mileage, so, any less wear has to be better
Secondly, a friend, who has successfully modded car and bike gearbox parts, will have a look
He has a huge home workshop, filled with specialised machinery, mills, grinders, and other stuff
He reckons he can make a big difference by some subtle re-working and re-hardening, (and maybe also....)
Substituting some other Hodna parts from his astonishing - fully-sorted-into-marked-crates - "useful-junk-collection"
HOWEVER
He has warned me NOT TO TELL ANYONE his identity, so I can't, as he has a tendancy to project overload and insomnia...
More later, promise to tell if it works out well, or not, all the best, from Ed

Update
Graf Van Salland kindly put me in touch with a Dutch bike breaker, from whom I bought a front brake disc
He also has a gear-cluster for sale at a good price
I aim to buy that when the November pension money comes in
Then I can see if any of my gear-change theories work out, or not.....
More later
All the best
Ed

Thanks for the update.

All sounds very interesting.

Thankfully, Bisto, you caused me to think a bit more.........
Could I poll forum contributors to see if there is a pattern to NTV 2nd gear prob.s?
Like maybe a particular range of VIN's which showed this fault?
Not heard of Transalps or Africa-twins, (or even VT500) 2nd gear prob.s.....
And then there are all those modded hawk-racers, as well, do they have the same cluster?
If not, and if the Hawk cluster is good, would one of those fit the NTV?
(does the final-drive affect the 2nd gear design?)
Maybe I should learn more about Hodna V-twin 'boxes before buying another NTV cluster?
Later today I'll call some motorcycle repairers and tuners, in case there is a known fix or swap
I wonder if the Hawk or NT700V clusters are any better?
One of my friends has a Deauville, another has a 1993 NTV, neither have 2nd gear faults....
I need to know more before buying a cluster, a gasket-set, and spending 'shop time...
Hmmmmmmmmmmm.......
More soonest

Im quite interested to know what happened did you ever fix it.
