did you buy it that way or add the header yourself?
if you added the header id guess it would be on lean side

I just installed it yesterday and I love it so I hope I don't have to put on the muffler or rejet

In theory you are increasing exhaust flow and helping the engine breath better, you may find optimal performance with a jet increase. But any time I add a part to a car or motorcycle, just by doing that, I feel psychologically Ive made it faster :laugh:
A dyno will trully tell you where you need to be with you jets

Ok so I took it out for a short ride on a 35 degree day and the sound that this thing emits is intoxicating, it's becoming an addiction. Definitely does not have as much bottom end power, but likes to get into higher rpms. Also is difficult to cold start now. Could be due to the lack of back pressure?

My worry is the motor over heating, but within minutes after riding it today I could touch the motor. Could be due to the cold ass weather. I wonder how it would react in summer time...

if its running lean she'll get warm

IR temp guns are pretty cheap at places like Harbor Freight and probably safer :lol:
