Question:
Dear Motorhead,
I have a 1998 ZL 500 and blew the engine. I changed it out with a ZR 600 motor, updated the carb’s with all jetting needs, but the machine is sluggish in mid range.
I didn’t change the CDI box though. Should I upgrade it or keep changing things out in the carbs?
Thanks,
Bob Cooper
Response:
Thanks for your email!
Bob, Dude – YES! Get a 600 CDI box! I can’t believe the thing runs at all!
You may need a seatbelt or velcro gloves to hold on when you get the full measure of power the 600 actually produces!
Good luck!
Motorhead Mark
