I'm not a big believer in an additive that claims to turn pump gas into race gas. Octane is not just octane as far as real racing fuel is concerned. Now having addressed that, there is probably no need for you to think a higher octane gasoline will help your miss/sputter in any way. You say you have a 95" but you decline to say whether or not you have changed your cams and/or exhaust and most importantly did you have the bike tuned after you completed the big bore and any other changes that were done? Most likely it just needs to be tuned.

Hello Boys,
Have or do any of you use the product Race Gas? I've had problems the last two times that I have ridden, when my bike feels like it misses or spits and sputters a little around the 2300-2800 rpm range. When I ride it hard, it runs great, but going about 70mph for a period of time I will get a missing, sputtering action??? I will also get it when I come to a stop, it idles fine, then I take off through 1, 2, and 3 and I will hold it in third gear about 2700rpm and it will do the missing/sputtering thing...I will go through the rest of the gears and it will run fine? No codes, new spark plugs, and it's a 95" build...Just thinking is this product might help...Thanks!

You bike/motor has a mech & or tuning issue (or both!) that needs to be addressed that no additive can fix.
Get your bike to a pro that knows what they are doing to fix your ride.

True but it should not make a bike/motor perform as poorly as his motor/bike is at times,thats for sure.

tried it once and bike liked it to a degree. ran cooler but i have already managed that issue. seemed to run a slight bit better over all but maybe thats cause it was 7.99 a gallon. nope its not worth it.

Hello men,
I think we have resolved the problem, I had a small hole (bigger than a pin hole) in my fuel line that was connected to the regulator. I had them replace all lines and filter and the problem is fixed for now! Thanks for all the replies.

Updated from last post...well the problem still exists...after changing spark plug wires, new injectors, time on dyno, calling tuner that tuned the bike and the engine builder, FINALLY I believe I solved the mystery...I did extensive reading and research and found that I may need to switch out the TPS and I believe this has fixed the problem. Expensive lesson to learn, my Harley Dealership told me that they can replace it, but it won't help. Well, I told them to do it anyway and it ended up fixing the problem. Hopefully this is the end to the gremlins for now!
