Race Fuel in late 80's bikes?

[mattman]

So I got an 89 Ninja 250 and my Dads got a 87 Kawasaki 900. We were thinking we would put in some racingfuel mix in but dont know if you can run leaded Fuel through. there old enough to not have Carbs. so i think it would work but want to know if anyone else has done it and what mix.

Thanks

they don't have carburetors?

No they do. At least the 250 does. Never made a EFI 250.

You can run race gas through them but you'll have to check on your jet size and emulsion tubes. They clog easily with leaded gas on that small of carbs. Why not get some no lead race gas?
