It might need a little fattening with jyst porting the cylinder . Plus ones persons porting is not the same as someone elses. Some people call cleaning up casting as porting. Thats why the factory page is correct. Its just a suggestion once you get to modding internals cause everyone is different.
A wetjet kraze has head and pipe and intake and the 46 mikuni comes with a 107.5 / 145. Yeah its not ported but its a stock ski with a warranty. 120/150 is plenty on a ported 61x with just a pipe.
120/150-20ish popoff
Do yourself a favor and use what people are saying as a general starting point. What factory recomends is fine for a starting point. Nothings plug n play.
Just doing the nozzle mod makes a huge difference. The UMI setup is not just a bolt on mod. I was told it needs some drilling or grinding or something so the 2014 I did we decided against the UMI setup. I was told the blowsion quick turn plate was betterbut still wasn't a true I cant confirm any...
The one in the middle will ride most like a reaper. The X2 will never feel like a reaper. They said the Reaper was designed by Blaster guys but they started with a superjet bottom deck. Why wouldn't they start with the blaster bottom deck? Makes no sense to me.
