i just rebuilt the motor on my 95 zr 580 efi.battery. when i first started it it seemed fine but as it ran awhile it doesnt want to rev up, its like its starving for fuel.it bogs when i try to give it any gas and also now it doesnt sound like both cylinders are running constant. im not sure, mabey i have the injectors plugged into wrong side or mabey the wires are backward, ive tried moveing them to other side but same thing. i have 100 psi compresion in both cylinders but the plug on the recoil side doesnt seem wet but the one on clutch side does.both have good spark also. could this be a stator issue? and could someone tell me what plug wire goes on what side and also the injector plugs. one of my injector wires has a 1 on it. witch side is number one? tks jeff

ive never had a cat before, so i was kinda lost, but i got it fixed. the dam battery doest hold a charge. i threw the charger on it and it runs perfect, so i guess i need a battery. boy do i feel stupid. but is there a certain way them injectors plug in???? just want to make sure.same with plugs wires? one injector wire has a white tag on it and i think has a 1 on the tag.

100 psi on both sides doesnt sound very strong to me. my 370 is pulling 133 and 132 on it,,, the important thing is both sides are within 10% of each other.

i tested this compresion right after rebuild, only had it running 3 min, the rings havent even seated yet to these brand new cylinders.
