I keep hearing a few things and wondered if the forum could help as I'm an old motorcycle rider and tinkerer but new to the CRF range, I am based in the UK and avid off-road adventurer

I recently bought a 2017 250 LA-H ABS bike (I had no clue about the models beforehand) and So I have some questions ...

1. is the T13 Front and T42 rear is the best combo? I cannot find T42 in the UK, but T48 are available - is that too big ?
2. I need a EJK is the can is changed - the previous owner put an Arrow can on the back for sound, but I don't know if that has any impact on the bike mixture and power?
3. the previous owner kept saying my bike is the more powerful version, but I cannot find any reference to that? does anyone know
4. Finding parts seems a challenge, I stumbled on CRF only via YT

Thanks

Nick
