So I have a garage full; probably 15 pales of methanol and Sunoco MS 116 octane Leaded race fuel in my garage that I use to run in the Porsche that I have no use for now that I switched the car to a Motec and E85 setup.

the Methonol I can find a home for but the 116 octane leaded fuel not so much, was thinking of having one tune on the Ducati set up for race fuel….anybody run Leaded 116 octane in these bikes?

Might be a bit of a ‘rough’ blend for these bikes, not sure how they’d like leaded race fuels.
Anybody with any experience or knowledge with it on these bikes?

PS my bike is catless and will remain so.

From what I’ve been able to research seems like the only downside is it fowling an O2 sensor with lead, but if you are switching back and forth and mostly running pump gas, with occasional use of leaded racing fuel the lead coating the O2 sensor would burn off between race fuel usages.

or one could simply remove the one Wideband O2 bung I’ll be using and screw a block off in the opening when running leaded Race Fuel.

I run 110 leaded in my V4, but like you mentioned, the O2 sensors are removed and closed off. I figure the sensor is only really necessary when making a tune, then can be removed once it's on a set map unless you're running an adaptive tuning setup. But I'm on the T800 UpMap device currently. I use the race gas mostly because I've had bad experiences with pump gas and don't really trust it.

I wouldn't get the bike tuned specifically for octane that high just because the fuel isn't extremely available. Wouldn't be fun to be done for a track day because you ran out of gas and can't use anyone else's without risking predet.

I have access to plenty of race fuel, I probably have 10 five gallon pales in my garage and my shop delivers it to my house on demand .

mid I were you I’d just keep some good additive on hand or a pale of methonol and add 4 ounces of meyhonol per tank of gas to you pump gas on track days, that will solve any pump gas reliability issues, and cost less if that’s a concern

hard to justify running race fuel without a tune for it, it’s not just higher octane, race fuel burns at different temps than pump gas and can change the afr etc.

sometimes race fuel can run LESS affective than pump gas if there isn’t a tune for it.

since mid 2000s I was using VP C12 and later on I went with U4.4

I forgot mentioning C12 I run on my small bike gsxr750 and this was full Yoshi engine on U4.4 on 2011 CBR 1000 with HRC top end.Still have those bike. I think 116 octane is to much for stock engine

If you must get rid of the fuel Steven, I would recommend mixing it half-half with pump gas and burning through it. I have about 20 gallons of Sunoco 110 that I am going through now mixed half with 93 pump.
