Down under, an idiot and a 400F

The side with the wobble is likely not properly seated. Did you inflate them until the beads "popped"? They need to go to like 55 60 PSI or higher a lot of times to get the beads all the way, then you back the pressure back down to riding pressure. My first tire I mounted had that and I took it back to the compressor and pumped it back up until the bead popped straight on both sides.
 
It's probably a variation at the weld? (you do mean the rim flange and not tyre bead?)

Ahh yes, I should have clarified that, makes a difference on the answere for sure.

Yeah it's a variation at the rim flange PJ. It's probably within 1mm but noticeable, want to know how/if I fix it. If I trued the wheel again I might be able to spread the wobble across both flanges.

I will grab a video, hopefully someone can advise me on next steps.
 
A little vid for you to look at. I'm not sure the problem is that bad after a nights sleep, let me know what you think. First edge has been done to 0.18mm runout left has a little more pronounced wobble:

Thoughts?
 
Checked the shock mount PJ, turns out the carbs fit with a mm to spare. Luckily enough the 2-3 carbs fall either side of the shock mount:

So with that in mind I fabricated a buttress to take some of the forward load:

Trimmed down the central seam weld:

Was only going to tack it in place but thought bugger it, I'll weld it all up properly:

Very envious of your welder! great to see the rear seat frame supports done too :D It's good to see you could fit in a support for thr shock mount, I would only say that all the pressure will be put through the welds as you have welded it in between the mount not at the back of it. If you had some of that plate left over from making the mounts, welding it to the back of the mounts and to the buttress I think it would be much stronger? (jm2c)

Good point Andy, not sure why I did it that way. I will see how it goes but to be honest I'm not too worried as its pretty tough. Worst case I chop out the cross beam and weld in a section of plate at the rear.

Where in Oz are you? If your in Sydney I'm happy to help with welding although my welds aren't that pretty yet.

Melbourne (the temperate state ;D) thanks man ;)
 
Sup dude? I've been coming back to this thread since I joined up on DTT a few months ago. Reading a page or six here and there. What an epic journey :D


Just thought I'd give some props.

Cheers Bud!

I went and read from the beginning the other day too, but didn't get all the way through. It's been a fantastic project and I've learnt a HUGE amount along the way.

I feel I'm on the home straight now though as hopefully it will have a shock and tyres by Christmas. Then it's the motor which hopefully means a shakedown run in about June '13 :)
 
Did you get the rim sorted?
Check it wasn't damaged in shipping, may be a variation in width where it's wobbling?

Not yet PJ. It doesn't look too bad on the swingarm. I will check the width with the calipers soon to check the width is consistent, I suspect it may not be.

If its not is it acceptable or should I pop an email to Buchanans?
 
For the prices they charge, I would expect everything to be perfect and would be really pissed if there is any damage.
They have been in business long enough to know how to pack for shipping around the world.
Check before you go nuts with them though ;)

Packing was good, no worries there. The rear rim does have a chunk out of it though on the inside, it's been anodised so has been there from the beginning. I will check widths all around and report.

I'm not a go nuts kind of bloke so we will see how this pans out in a pleasant way.
 
Figuratively speaking, pretty difficult to actually do much from 8,000miles away although you could send a nasty e-mail ;D
You have tried loosening or tightening spokes 90 degrees to the bump?
Sometimes you can pull a wobble away from distorted rim doing that, particularly if only one side

I find you catch more flies with honey then vinegar. I'm not saying I needs resolution as the wobble is minor and still within Honda specs, but I may ask them about the tolerances if it turns out the rim is inconsistently wide.

The ball is then in their court.
 
A jog at the weld is common on all rims and worse on older Akronts which typically had a lump or a gouge where they tried to buff out the weld.

Check out the link to the video teazer and let me know if its a weld seam bump. Looks too big to me.
 
Rim width is no longer in question. Consistent to 0.6mm all the way round, I will re true the rim at some stage from both sides to eliminate as much if the wobble as possible.
