Fouled plugs

[brewcrew]

Hi i recently put a new exhaust on my k9, there 2 1/4 without baffles, i had a kerker header on it, well i went to start it the other day and it was runnin on one cylinder, so i took the plugs out and they were black and wet and shitty, ive checked my plugs before when the other exhaust was on there and they looked good , would changin the exhaust cause that and it also seems like its a little harder to start, is there something i can do to fix this , i was thinkin about puttin the header/muffler back on , but i like it loud

Yup you need to rejet your carb when you change pipes. You are way too rich. There are a ton of post on here about how to do that. Good luck!

BEFORE you rejet your carb, try installing a good set of standard NGK V-Power plugs,set the gap on them,and Re-adjust the air/fuel mixture screws.........see what that does:2thumbs:.....
