This ought to be good. Sub'd/
I have ridden one- both turboed and unturboed. Did you know that this was the only turbo bike that was slower in the 1/4 miles than it's un-turboed counter part? The dummy pipe I found interesting as well- I forgot, it served some function still IIRC?
Bike was painfully slow on the low end, but once the turbro spooled up it was gobs of fun. The guy that owned it is a former Kawasaki dealership owner and part owner now of a a yamaha shop. He is pretty old now, but he won a couple national drag racing events and a full on championship.
He raced me on a Z1 900 and ate me up LOL- but is is about 100lbs lighter than me.
I can't wait to see what you do to this thing! Getting rid of the turbo lag would really wake that bike up!
