Hello guys, my Honda is VFR 400k.I have to instal camshafts,but didnt take picture of the marks before,so,anybody knows the firing order degrees?I know that firing order of nc21 is 1-3-2-4,but i mean 1-?degree-3-?degrees2-? degrees-4.On my opinion it have to be - 1-180dgr-3-270dgr-2-180dgr-4.Am I right? Any help with manual-even in japan?Thanks,guys!

Howdo.
The bike is a 180 degree V4 - so you want to go and use the detail for the VFR750s
Don't guess - you'll kill it, as I am sure you know.
The alignment will be with the punch marks on the cam shafts and the cam holders and also aligned with the timing marks on the crank. SImple to do if you have it in front of you. I'd be sure that the info is actually on here somewhere - so get a google on it and it will lead you here to the right thread i am sure.
Welcome..
