Do I need a + stem for oversize tank

[Mercedes]

What to know if I need a longer stem to give clearence for the tank? And What will I need to change(brake hoses,trottle cable,clutch cacle...).

I have the tank on the way. Hope you guys could help.

Tank works with stock steering stem on the 06 & 07. Not sure on the 08 since they made it anti-vibe.

If you go with an aftermarket stem you will need a +1 or +2 for clearance.
