ok this is my results, i won't take anyone's pics.. don't worry
@cuplis : ok i am a bit forgot.. lol.. it must be my age.. minimum comp is 490 kPa (4,9 kg/cm3, 70 psi), standard is 560 kPa (5,6 kg/cm3, 80 psi), maximum 630 (6,3 kg/cm3, 90 psi) all at 500 rpm
@king : as for stock carb no jetting required as long as u don't change anything like comp ratio / cam.. top speed for stock carb and stock vixion block about 125 - 130 kmh here depending on rider weight, tire size, and stock sprocket..
@jay e.l : u can try those, but it's better to enlarge ur crankcase hole.. i am satisfied with my 23 hp results.. except those kits can provide much power with increased durability.. isn't that for Yamaha Majesty ?
as for Vixion bore up it's plug and ride kit..
