Looking for information in Big bore mods for the mach Z 1000
anyone here with information on
the CS 1100 and 1240 or bikeman 1100 and 1250?
speed 1000 feet and top speed compared with stock Mach Z 1000 twin.

thanks for your help

from what i've seen and heard.... you are better off going with a n2o system rather than a big bore. Big Thunder Performance has a very good kit that will run with the 1240 and smoke the 1100 kits.

^^ yep. gotta agree. some of the guys that have the 1200 kits installed role onto the lake like they already won. when a well setup stock mach z will run with them. a well setup old school sled usually spanks them pretty good for speed.

them big twins are drag motors not speed motors. there is a big difference between an engine designed for making speed and one that is quick in the short bursts.

Save your money, the best bang for the buck is spray. Ya it's not all the time power, but it's alot more than any of the big bores you mentioned. The big bores aren't all that they're cracked up to be, the hp claims are very inflated. I've been witness to several.
