Gen 1 Help please

[Mr Brown]

Ok guys i took every little notation into consideration.... And this is my out come.
I changed the oem air filter to k&n
I changed the exhuast system over from voodoo slip ons to two brothers racing*I still have the factory header with the cat still attached*
I bought irrilium ngk plugs
And I feel a slight gain in hp but im still running rich.... still smokes a light grey smoke and it burns da eyes and lungs.... It smells as if its burning extra gas... Soooo whats next???

Couple of things, changing slip ons is unlikely to change power. You don't still have the cat attached, gen 1 don't have a cat.
Changing filter and plugs without knowing what the problem is won't get you anywhere, in fact it's exactly what we told you not to do...
I'm with Kiwi. Take it to a shop. Good luck.
