Greggh here.
Just got my 110k 98 STD back from Attic Rat on Saturday.
He did his mods to an engine that i had bought and delivered to him, then swapped the motors on my 98 Std. He also did some wire harness replacement and other fixes for me as well.
Bob aka Attic Rat, Really truly knows the ins and outs of these Valks.
I will say that he has brought new life to my fat lady and she runs better faster than she ever has!
A much smoother ride increased mileage and one heck of an increase in overall performance.
Got back to Omaha NE after a 7 hour ride and ran into a friend and his "Fast" Harley. Got next to each other and......... Well, I can honestly say that my friend knows what the back side of my VALK looks like now.

He just simply told me that Damn thing is FAST! What a Beast he said.
Thank you Bob for all your impeccable work and Mostly Thank you for being an Honest and great Friend!
If anyone might ever consider to get their Valk modified?
Give Attic Rat (Bob) a shout.
It will be the best choice you will ever make regarding these beautiful Fat Ladies!
