125-200cc 2000 husqvarna cr125

Somehow I managed to trade a 9 year old set of shaved paddles on wheels from a Rhino SxS for a 2000 husqvarna cr125. The bike runs but has quite a few problems, almost every bolt is either missing or bought from a hardware store with a 13.5mm head on it, the rear wheel is MIA but it has a older honda cr125 rear wheel on it with the axle blocks used as the spacers between the swingarm and the hub
The bike idles perfect but when you pick the throttle up a few 1000 rpms it starts to cut out super bad and will die if you don't lift. PO said he thought it was the CDI/coil and gave me 3 of each with the bike. Carb is cleaner then if the bike was brand new. Is the any way of testing a coil for the amount of spark it puts out at higher r's? as well as testing a cdi?

Also for my last question, does anyone know if a 94 wr125 rear wheel will fit the 2000? I know the 250's and 360's were pretty unchanged for most of the 90's Italian years however unsure of the 125's.
