So hopefully I can get some advise from the clever guys here  . I have RGV VJ23 Forks, they were all I could find at the time, and seemed to be the right thing to use, but I didn't realise the 23 had an electronic speedo.. So having got a 22 front wheel and speedo drive I found the issues with wheel spindles and fitting. I started messing with this ages ago and still have not figured out how to get around the problem. The VJ23 forks have a nut in the fork and not a threaded fork leg, so having eventually manage to get a nut (from Japan at stupid money) of course it won't fit, its designed to go through the fork to the wheel edge, not to a speedo drive. So here's my thoughts, either get a shorter wheel nut made, the 23 item I think is titanium, so can't cut that, or I've been thinking recently about changing the wheel bearings and using a bigger spindle, this would maybe be cheaper to have made and be more successful! So you clever guys who build these amazing machines, please pass some of your wisdom this way, I need to get this bike finished one day but this little issue has been put to the back for the last 3 months. Thanks, Phil |

If only I could, not seen one for sale in the last 6 months. I also asked on the RGV forum, no chance!!

Go for the largest diameter Axle possible.
As Bonus It's the Axle size and it's method of Mounting that makes Forks rigid.
Not some Lame Fork stiffener sold to to the unwary.

Thanks, Phil Hi Phil, I think you are on the right lines with a new spindle if you want to keep the 23 forks, but are you happy with an electronic speedo? You could buy a pair of VJ22 fork legs or GSXR400, and then you keep a cable driven speedo. HTH, Mark

Thanks for the input guys. I'd like ideally to use a mechanical speedo drive, so what about if i could fine one where the nut would go through it and tighten the wheel as designed on the 23, it maybe that one of the larger Suzuki speedo drives would be suitable. Does that sound feasible??

Can you post up a pic so we can understand the problem
Cheers

All I have is this at the moment, this is a zoomed in cropped pic of the front wheel. I'll take more when I get home again. This just shows the VJ23 nut in as far as it goes as its hard against the speedo drive.  RD WHEEL by Philip Millard, on Flickr |

On a normal set up does the wheel nut clamp the fork leg against the speedo drive which is then clamped against the wheel bearing??

Just to clarify, I have had modified spacers made for the other side and the wheel is central, its just the case of getting nut to tighten the whole thing up.

Right, that clears it up a bit
On the vj22 the lh fork leg is threaded and the right has a clamp for the thick end of the shaft
The spindle goes through the rh spacer, the wheel, then the Speedo drive and into the threaded fork leg so basically clamps the wheel to the left fork leg then the rh fork clamps to the thick end of the spindle holding it all in place
On the vj23 it looks like the set up is similar other than the lh fork is a clamp like the rh side
I'd think the solution is to get a new nut made for the lh side.
It would need a flange to go up against the outer of the leg and be the correct length to but up against the Speedo drive.
Then if you fit the new nut/adapter (like a top hat) in the left fork and tighten the pinch bolts you can then tighten the spindle from the right end then tighten the right hand clamp
Hope that makes sense

You may get away with getting the nut you bought cut down a bit

Hi Steve, that makes perfect sense, so the new nut would be the same width as the fork leg I guess, are just a tad more?? I'm not sure I can get the new nut cat down as its titanium, well I think it is, I'll get somebody to have ago at cutting down, it would be the easier option.
Thanks, Phil

Yes just long enough to but against the Speedo drive
Best cut down on a lathe
