hello im from finland and i want to ask some questions , what cylinder is more powerfull , malossi mhr80 or barikit alu racing mod 80 ? what carburator is good for mhr80 or barikit mod 80? and what exhaust is best for mhr80 or barikit mod 80? does the mhr80 work with racingline 70? and what is the difference between barikit mod 80 and barikit 80 , is the mod more powerfull? and how many (hp) i get from barikit or mhr80? thank you if you answer

As exhaust i should take the Yasuni R3/Malossi Supermoto/SCR Corse RacingLine 85.

And the carburator can be between 21 or 32. (I schould take the 28mm Stage6/Koso/Keihin)

how mhr 80 works with racing line exhaust it's 9000-145000 ? can i use standard electric? do i need to do something to blocks?
