Bought the bike used, not knowing what was inside it. I learned that the guy who owned this before me was a real gearhead, so he put some stuff on it.

From what I saw with my eyes, he had an Ohlins rear shock & Two bros exhaust. It's claimed to have racetech front springs in it as well, but I haven't checked yet.

I've made quite a few nice discoveries so far. Popped open the airbox & discovered a K&N filter. Went a little further & saw emissions was removed too. Popped the carbs out & discovered that there's a jet kit installed in it. I'm not sure if it's a dynojet or factory pro kit, but there are 4 holes in the front of the carb slide. Do they come stock with 4 holes?

Now a jetting question. The carbs have 180f 185r mains installed on the bottom most clip with stock #45S slow jets. Not sure what the mix screws are at. The guy left only one airbox snorkel open too, the ones that come on the K&N were nowhere to be found.

NOW, what I want to do is:
Install two long velocity stacks in the airbox & cover up the open holes.
Get an Ignition advancer (if there's not one already installed)
Dual rear emulsion tubes (needed from what I heard)
Reduce TPS from 1500 ohms to 500.

Do you guys think I should get a new jet kit? I was thinking about ordering the Factory Pro 1.1 since I don't know if the 180/185 with the #45 slow's will be good enough for everything I want to do.

Suggestions?
