Up here in the great white north we do some indoor riding at the local go cart track. Just finished setting up my boys RM85. Because running clean is an issue most guys run Ipone oil at 50:1. I usually run non ethanol 91 octane fuel but was thinking I’d mix some with ( maybe at 50:50) with vp110 that I have. My theory is that the bike will run slightly leaner( and cleaner) given that engine loads aren’t as higher as outdoors we should be ok. Thoughts?
re-jetting. There may also be some performance lose with the fuel burning slower. This is a border line case and may work ok with minor jetting changes.

Uh, skip the leaded fuel.
You can always rent a multi-gas meter and test the spectator area. The common sensors are CO, CO2, NOx, SOx, CH4.
The Alta is a great idea except the rider is 12 and weighs as much as the Alta batteries lol

Also, if you are currently using a much richer oil ratio like 40.1 or more, then the jetting will be a little leaner at 50.1 but not by more than 1 jet size at the most.
Also, since it runs rich now and you want cleaner exhaust, you should lean it out. There is no point in trying to reinvent the wheel by mixing fuels etc.
Bf884 is right in that more oil in fuel causes a leaner air fuel ratio.
