Yo ppl
im considering doing a port and polish on me little 250VTR spada to increase the HP.
also thinking of increasing the port? is it worth it on the long run? engine life span wise. and would you reckon id be seeing more HP gains compared to a normal port and polish. breather mods have been done (increased air intake also with a increased exhaust piping and can)
thanking you in advance for the tech information.
