mystery drag bike? joey krafty?

i recently purchased a 77 kz650 that has been parked in a barn for 16 years. from what i was told the previous owner passed away and it was parked. it has a massive extended swing arm that reads high risk racing so cal, on the side. upon cleaning up the swing arm i found a personalized message that reads.. thanks, joey krafty allied A-1. i am clueless and nobody knows anything about the bike? if anybody has ever heard of this swing arm or this person, please let me know. the bike sat for 16 years and it was running in 6 days after i got it. even in death he knew how to store a bike. thanks.

Can we see some pics ? Some one might be recognize it if they seen it .

Might consider bumping one of the earlier posts rather than creating a new thread with substantially the same inquiry.

Bumping refreshes the former inquiry, and also retains the earlier information and replies.

Creating a new thread starts at ground zero, absent benefit of prior responses.

Pics are shown in both former threads.
