How are you gonna cruise at 80 when 90 is your top?
Realistically you'll need to top out at 107, then pull back about 25% on RPM, which would give close to 80mph.
525s in anything wont do it.
I'd call Phil and let him finish you a 39 w/ Zuls.
If you are serious, contact Rick, OSG, he's got a gladiator w/ zuls and runs 114+. He'll give you an honest opinion of Lipship and Zul.
