Hallo Claus, wenn der untere Ring 7mm hat dann ersetzt er die hier in Kevin Emery's Zeichnung 6 Stk. Spacer/Distanzen, oder?
Aber wofür sollte dann der 2. Ring sein? Evtl. ein Universaladapter für eine andere Nabe? Suzuki GT oder Honda CB?

Hello

There is some misinformation here.

First. The document was created by Robert Lincoln. I just asked it to be uploaded here. However I have done this conversion so have some experience on the wheel build.

The adapters shown on the axle are not required, you need a combination of TR1 and XS650 spacers on the axle. Exactly as described in the drawings.

For the round spacers I think I have an answer for you. The drawing calls for 7mm spacers. I achieved this by placing large nuts under the bolts fixing the rear sprocket to the hub. This could also be achieved by using one of the circular adapters. HOWEVER. I found the drawing was wrong. The spacers required should be 12mm. (As measured on my bike, yours may be different.) Perhaps the second spacer was used to increase the offset of the rear sprocket from7 to 12mm?

Warning. The sprocket sits over a rim on the rear hub which locates it. If you use two spacers as shown (or even one thick spacer) it is unsafe. There is nothing to locate the sprocket correctly, one spacer can slide over the other and it all relies on the side forces on the bolts retaining the sprocket to the hub. I hope that makes sense? What I did was to have an adapter made that was 12mm thick. That adapter was made to sit over the ring on the hub and also has a raised ring one it, exactly the same as on the hub. In affect the adapter located on the hub and then the sprocket could locate on the adapter. I hope that makes sense too?

I do not have a photo of it.

On the lacing of the spokes on the rim you also have to check the alignment of the rim with the hub. Mine is very critical as I went for a wider hub. My rim is aligned dead centre with the hub. This is critical so measure and check carefully.

For the  lacing of the spokes I had nothing to compare it with. The wheel builder I used is very experienced so I left it to him, All I can say is it works. I rode to the rally last year with no problem. I have included three photos below which shows how they are laced.

I hope this helps?

Regards
Kevin

Yep. facts do tend to silence people.  

Hello Manniku

The rims and tyres are a personal preference so have chosen the ones I wanted. There are others available on the market. I wanted the widest rims and tyres I could fit on the bike without altering the front forks or rear swing arm. I believe I have done that.

The front tyre just fits in the front forks. It is tight, you have to remove the bolts that hold the front mudguard in place to get the tyre in then replace them afterwards.

At the rear the alignment is critical and you will have to pay careful attention to alignment on the axle spacers, the rear sprocket spacer and the alignment of the rim to the hub for the wheel build.

I have chosen Avon Road Riders for two reasons. 1. I like them. 2. They are the only tyre I could get that would supply sizes that fit the front and rear rims.

I have fitted inner tubes to both tyres.

Front.

Rim: Morad 2.5 x 18
Tyre: Avon Roadrider 110/80

Rear.

Rim: Morad 4.25 x 18
Tyre: Avon Roadrider 150/70

Best of luck with your project.

Kevin
