Just for another reference point, my bike never really had many issues. I deleted the cat and still didn’t have any issues. I got a tune a couple weeks ago and I felt like it actually ran worse the first couple times riding it. Now it feels exactly the same. I really don’t feel any extra...
I don’t think my bike runs any different without the cat than it did with as far as I can tell. I don’t have any of the cold start issues many folks talk about on here.
