New here and got a somewhat noob question.
I've always been told that engine management and tunes are not necessary if you still have the OEM cat and just a slip-on.
But my research here and on other sites is giving conflicting advice. Some say a tune is ALWAYS needed.
Regardless, I'm looking at getting a 2012 ZX-10R that has less than 4,000 miles on it. The bike has a generic slash cut-tip slip-on.
The owner says it still has a cat, but I'm not so sure. I'm also not sure if its been tuned properly.
I can get the bike for a great price. Wondering if I should risk it and buy it, and just get a name-brand slipon and a professional tune after.
I'm just worried that possible engine damage has already occurred to the motor with so few miles on the odometer.
Here's a picture of the bike.
