10+1 - reckless bubble push with a limper level

[Isura]

I think I have some folding equity, but I never know against these guys at the 11s. Looks like I'm at best 50/50 when called. Needless push or good play?

Depends if you think the limper is limping because he has a big hand or just something playable. Has he limping like this before with a big hand? Otherwise its a decent play.
