I know most of you don't have this option, but we have 2 choices for fuel, 93 unleaded and 93 leaded, I am wondering if they ever adapted these engines, I believe mine is a '94, to run with unleaded fuel, I would prefer to run without, tonight I topped off the tank with leaded. I guess it would depend on what fuels were available in India...

Leaded fuel is not necessary in these engines, unless you have a model built before the lead-ban, such as in the 1960s.
All the newer models have hard valve seats, and are perfectly fine with unleaded.

In your case, you could pick either leaded or unleaded, as you please.
Either one would work fine.

Where do you live?

Thanks Ace, I will stick with the unleaded then.

Hi RGT
I have a number of bikes that should run leaded . I don;t worry about it, uaually it takes quite a while for the seats to need attention through using unleaded. I'll fix them then, meanwhile I  ride them.

 I wonder if all post 1990 Bullets are built for no lead fuel or just the ones exported to Europe and the U.S. ?

Generally speaking,  a single type of valve seat will be used on all the engines, for the sake of manufacturing simplicity.
The hard seats will work for either type of fuel, and that would be the default selection when dealing with diverse markets.

Makes sense.
 Ttandard non hardened valves and seats went the way of dinosaur in the ( U.S. anyway) circa 1973-74.   
 Still I wonder though how much longer hardened valves and seats would last if we had lead in our fuels today.

If I had my choice I'd run the leaded.

How about lead substitute, I there any reason to consider this additive as a possible benefit...

[clamp]

I think you will find that India is using ethenol fuels too. They certainly are here in Thailand and for some time, infact sometimes its all I can get and soon will be all I can get.

     I have given up worrying about it,-- if I ever did.

   I cant tell the difference on any of my bikes.  I use B5 diesel in the car too.

Anyone here using lead substitute,or any other fuel additives?

There are several of us that use Sea Foam in the gas. It is the only known additive that will actually clean an oxygen sensor. A little Sea Foam was a lot cheaper than $249 for the sensor on a Mazda...    I can also tell you from my own experience that it will help keep the carbon from accumulating on the the head and piston. When mine was tore down for the first time after 18,000 miles the mechanic called and asked me how long it had been since I had done a de-carb...  never.
   yup, I just tip a "glug" in every tank or so...  - Mike

Thanks,Mike...I've been adding an ounce or so of Marvel Mystery Oil every tankful,and haven't had to clean my carburetor in over 500 miles...I'll try a little Sea Foam next fill-up...

bullethead63, Sea Foam is indeed a good carbon remover. Do not be surprised if black cloud of carbon comes out of your bikes tail pipe. It will stop after a minute or so.
