Welcome from NJ,
I have the same bike but no experience with 8k Led. The pulsing you are seeing may be the system jumping back and forth between High and Low beam. If the EHC doesn't sense the correct voltage drop on the Low beam circuit it automatically goes to the High beam circuit then if it still doesn't see the correct drop it will switch back to the Low beam and so on and so on. This could be your pulsing issue.
There may be a fix but it's out of my realm. Like Mick says someone on the site will probably be able to help you. Lot's of guys have switched to LED with success but I don't know if they were using an 8K . Good Luck
