I'd run it in a heartbeat! Just be SURE your mufflers don't have cats in them and add a little Marvel Mystery Oil to it so you have a little upper cylinder lube.&nbsp\\;Avgas tends to have less lube than conventional fuel. I used to run it in my old street rod with Hilborn injection and 12.5/1 compression ratio!&nbsp\\; Never had the first problem related to the fuel. The mechanical FI was a whole different story!

Big debate on this when leaded gas went away.&nbsp\\; I had 71 Mach 1 and debate was with out the lead would you have to harden the valve seats.&nbsp\\; There was never any definitive proof either way, so I just left it alone and it worked fine.

FYI, &nbsp\\;it will quickly coat your 02 sensors with lead and ruin them.&nbsp\\; [:@]

Ride well,

Interesting topic.&nbsp\\; From what I've read here so far, I'd still be scared to run it in my $20k machine.

What bad finger said . If you have a bike with O2's in it don't run it . That will be your only down fall . I will be fine in all other aspects of the motor .

I AM ASSUMING IT IS 100LL.
YES IT RUNS BETTER, AND THE LEAD DEPENDS WHAT YEAR YOUR BIKE IS.
&nbsp\\;
I USE TO USE IT IN MY 73 SPORTSTER.
&nbsp\\;
HOLD ON WHEN YOU TWIST THE THROTTLE
&nbsp\\;
YES HE CAN RECYCLE IT IF YOU DO THE SIMPLE WATER TESTS., NOT A BIG DEAL BUT IF IT'S FREE HELL YEAH
&nbsp\\;
PLUS I HAVE BEEN IN&nbsp\\;AVIATION FOR 30 YRS
