125 shot jet size HR?
Anyone know the jet sizes for 125 crank shot or 100 whp shot on an HR?
Also, do you guys think it's reckless/dangerous to run the 125 crank shot on a 100 crank shot tune with 4 degrees of timing retarded.

Def not dangerous. I'm using more than stock timing on a 100 shot and seeing no knock or anything. Keep your A/F's in check and use good gas, and as always back off if something feels amiss.
NOS jetting is about a 40/22 for a 125 shot on this platform, according to thier tech line.

Thanks for the info. Since I created this thread I got in contact with ZEX and they told me jet sizes are 46/25. That's quite a bit bigger than what NOS recommends for 125. Eh, what the heck. I'll get it tuned again to be safe.
