I would check the primary and secondary resistances of the new coil , I have had them bad right out of the box. I would check to make sure im getting a good ground and good power to the CDI , make sure you are getting a good 12v to the coil, make sure your frame and engine ground are good, this may be extreme , but before I start buying expensive parts, I would take the side cover off and inspect the stator and pulser coil for trash or debris or anything out of the ordinary, loose bolts crimped wires etc.  I know you have probably done all these things, im just going over a list of what I would check and double check.

Im sure the bearings will be fine, I actually have been impressed with the quality of some of the aftermarket parts I have purchased, I am also trying to bring a 2000 ATV back to life on a budget, I would have bought them also at that price, but as KP said be sure and mic them and compare against the old to make sure they fit correctly.

If the spark plug cap comes off the lead try taking that off and checking the spark. The cap might have too much resistance or a short. Also have a look at night and you might see sparks running along a rubber boot or across the coil to earth.. If you have a timing light, connect it up but put a screwdriver through the pickup, then use the screwdriver as a probe looking for leaking voltage.. It'll make the timing light flash if there's an HT leak..

That's one beautiful bike

Just a note new plugs can be bad right out of box I had an old mustang once put new plugs in and wouldn't crank up. Chkd plugs and out of 8 brand new plugs only 2 was firing.something to ponder hope you the best.
