I just purchased a port and polished, bored cylinder which is bored to 67.5mm. I am just wondering what cc that would put my blaster at. And if you have any recommendation on jet kits let me know
I came up with 203.97 cc
From spicer bore and stroke calculator.
What carb are you running?
If stock ussualy just the main needs to be changed.
Us only oem jets. As the aftermarket stuff has been known to not be accurate in size

What other mods do you have.
Pipe?
Airbox lid on or off ir modified?
Are you premixing your gas?
Temp?
Altitude?
And what jets are in it now.
These will all play a role in jet size
Ut will help the guys give yoy a better answer
