Clutch shuddering

[Jack]

I'm riding a 2004 R3. Done only 34,000 Kms
I've noticed the clutch has developed a shudder when I take off.
Has anyone experienced this and what advice can you offer

The oil was changed prior to the mods and prior to firing it up for the fist time.
I used Motul 5-100 10w-40

 

[TURBO200R4]

What mods?

 

[Jack]

Nothing mechanical. All cosmetic

 

[R-III-R Turbo]

I haven't ridden it a lot because its a recently completed total rebuild and its still too cold and wet here.
Its had previous owners so its possible its been worked on although its only done 30,000kms.
I just noticed it recently.

I wonder was the clutch reassembled correctly.
