Default Re: what are some of the best mods to do?

the best mods are as follows in this order
0 tune carb
1 port and polish and port match
2 deck your head or high comp head
3 tunned x chamber power band or strait pipe for WOT racing
4 larger carb 16mm dellorto phbg or sha 16.16mm or mikuni vm18mm or
5 piston mods IE... grind ramps, cut skirt, and lighter wrist pin and bearings
6 reed valve intake arrow or rock solid

the grubee gt5 on the last pic has the mods listed. high comp head, port and polish with extra 3rd transfer port ground, tunned x chamber exhaust from arrow, arrows reed valve intake, delorto 16.16mm sha carb, and a modified piston ie .. ramps cut to modify transfer port timing and exhaust duration, and better bearings.

sells for like 600$ but can be built for less than half that if you have the mechanical know how
