Okay sport, the only way those spokes are gonna last is getting that spokering snapped on and centered, and you've read up on Jim H. "Just Cruising".
You need a hose clamp, the size of the handlebars, to hold on the thottle when that time comes. You'll have to grind a bit off the sides, maybe one inch of the strap, to fit it in the throttle and pull it thru with your needlenose.
Just unhook the back brake cable completely, let it flop out of the way, that will be the last thing you'll put back together, makes getting the tire on and off easier. You may have to adjust the pads some, but you won't know until the end.
Start with the spokering. Get that part right and you MIGHT make the skinny spokes work for a while.
Check the four holes on the end of the strap, make sure the middle two especially, fit over the bolt in the mount. Last ones I put on had to be bored out a bit, better to know beforehand. If the strap holes fit over the bolt, then attach the strap to the bike first, (when you put the axle mount on, you slip the front of the engine mount in the second or third hole.)
Like I said, you'll probably have to do the axle mounting twice to get it just right...
We'll be standing by if something comes up.
