bondi racing makes a kit with jaws pipes for the triple in a zx.I spoke in detail with chris on this combo,the main question I had was did he weight a sled before and after? he told me he did not have the scale to weight the sled,but he did weight the parts removed and the parts going back on (800 twin mxz),there was only 10 lbs differance now I dont know if this is true or not but thats what was stated by chris, he said the twin 800's are pretty heavy engines.
