1st mods went well. I have a 07 400 ex
Used a HMF slipon and K&N filter + dynojets.
I set it up exactly as Dynojets instuctions say and it works awesome. It might be a little rich yet. Im changed the pilot to a #40... (couldn't get a 42 in time) and the main jet to a 146. That really helped starting. Im 3 and 1/2 turns out as the instructions indicate and the thing runs great in all gears.
What a difference on the low end after the upgrade. That slip on sounds great!
So for the 300 some bucks put in...it really showed some returns. I had a blast yesterday.
