Alright after I ran the 3rd tank of gas through my new 400EX I decided to start modding it. I already ground the welds out of the headers and thats about it. I ordered a EHS racing airbox lid (basically an open airbox). The next choice is between Exhaust or a power up kit with a K&N and a prefilter with a jet kit.
Should I add the air filter before I add exhaust or should I run the stock filter in an open box with a new slip on?
So the next questions would be:
If I run a K&N with a open airbox and stock muffler what would my jetting be?
If I run a open box with a stock airfilter and a Lexx what would the jetting be?
I run between 250ft to 1000ft elevation and do run in the cold quite a bit.
Thanks!
