Gt125 naked 2016

Hi all,

first post and new rider. Went for hyo gt125 unfaired and love it! Total noob with bikes though so couple of questions if anyone can help

Bike seems to take a age to warm up. Is this normal or is there anything I can do to improve things?

Thinking of updating a few things. Getting 520 chain kit conversion done, maybe filter and jets. Anyone know if chain conversion is straight forward (will be taking to a mechanic!).

Any other basic modding advice?
