Hello all,

I am new to the forum & I have been looking to see if anyone else has posted about what I am after but I can’t seem to find it.

I have a Lexmoto Assault (HJ125-J) in blue and I am looking to replace the exhaust with a Lextek YP4 exhaust system. Once I have changed it over I would like to tune the fuel to help with the large exhaust. I have never done this before so I have no clue what needs to be done. I have been looking at different carb jets but I don’t know what would be best.

If anyone has any information about what I could do, I would be really appreciate it.

Regards
