So I have been using my '86 Brat for 40 miles commuting and I just love it.
I've got a question for you today.
What octane should I use? It still has a stock single carb under the hood.
I have been running with the lowest octane(87?) and so far so good.
But just realized the owner's manual says 90????
So I need some feed back from you guys.
Thanks in advance,
