T509 Engine Swap

Hi all,

I recently bougt a 1998 Triumph T509 in a immaculate state and I am interested to swap with a later (2002-2004) engine. It is my first tripple but (as you may know) it feels quite underpowered. I don`t want to get me a 2005 onward bike because I am just so in love how my bike looks and feels.

Can someone give me some advice which engines will fit under it. Also how many hours will it take to replace the engine with a newer one(hours) I am not a mechanical and have to bring it to a shop but like to hear some unbiased info on this.

I hope someone can answer my question.

Thank you

Kind regards,
Peter
