alreet john, cheapness ...a DR177(180) kit, 21 tooth clutch cog, standard exhaust, and up jet the 20mm carb to a 110 or thereabouts, no crank /crankcase mods needed. they can be quite tight new, so give it a hone out before fitting. good cheap set up.

thats one possibility: take DR if you just want a simple pnp tuning
additional use
- a 24si carb, but pls widen the hole in the carb bowhl
- GrandSports piston rings, they cant break as the normal rings
- a sip road touring exhaust of course
- strenghten your clutch basket

but if you think of more tuning stages
of course take a polini 177, gs piston rings, siproad, 24si carb, kty vcdi, 21t clutch cog, stronger clutch basket
later on you can tune it further more, check my utube channel out, the race between gts300 and the green super 150 is a polini 177 si24, 65/23 (!), siproad setup
