Hi, just getting into vintage racing and have a couple of projects just about ready to roll, 79 CR 125 and 78 RM 250....the manuals say to mix at 20:1. I run 40:1 in my new KDX though the manual calls for 32:1. figure that's not leaning it out too much.
Trouble is, I don't want to carry around different cans with different mixes, 40:1 for everything would simplify things.
However, from the factory recommendation of 20:1 to 40:1 is TWICE as lean. Is that acceptable? I was thinking maybe just run everything at 32:1 as a compromise but my KDX is jetted perfect at 40:1.
Thoughts? Thanks!
