Help with jetting

[04450rrider]

I just bought my ron woods exhaust and put it on. Before i put it on i had a slip on pipe with airbox lid removed that the dealer put on and jetted. When i put this new pipe on i didnt change jetting because i was told i didnt need to. So i went to the dunes and rode it for a little. then i looked at my plug and it was white. Could anyone tell me what might be wrong? I need help ASAP. Currently i am running a 175 main.

well it sounds like your running lean.. You may have rejet it. if you put on a full exhaust you have more airflow than you did before when you just had the slip on.

That is exactly what i was thinking. I was wondering why they told me i didnt need too.

How many jet sizes do you think i should go up to? 190 maybe?
