My friend play with is jetting ont his 2004 450R

Here the mods :

Stock air filter without lid
Hotcamstage 2
Stock pipe with no baffle (not the HRC ... nothing)
HRC kit (all but not the lid and the cam)

Temp around 68F
Elevation below 1000feet

He is riding the Mj185 and the mj200 and he say that is sparkplug doesn't change with the 200 vs the 185.Is sparkplug is gray.

I don't have seen it but I think that he did something wrong.

What main jet does he will be ok?
