is further tuning worth it? ie using a BIGbox (bbS) a vcdi ignition and a light flywheel? = aprox 400,- more BUT how big is the difference on-road? see by yourself:
normal rotary valve si carb box exhaust setup with just sip road VS more advanced: bbS+vcdi+1,5kg flywheel
result = 1,5s faster, but pretty the same till 80kmh
good2 know if its really worth it
just for city? nope, not needed ;)
honest acceleration, driver 190cm 100kg upright,
setup:
FMPolini 177, longstroke (186ccm), si25, sip road v1 exhaust, , teninch central spark plug cylinderhead, teninch honda cnc clutch, 65/23 transmission (=px200)
