well, i have run just about every carb you can imagine, on alky and gas....I LOVE LECTRONS on ALKY!!!!! i have had gas lectrons, but the keihin 40.5 or the mikuni 41.5tmxx just seems to work so much better on gas IMO. i have lectrons on all my alky motors. i really like the keihin 40.5. It has been my Gas choice forever. I recently just bought a 88 from a buddy that has a 350 non PV cyl, and t has the 41.5 tmxx, and im in loe with that carb. Super torquey, and a ton of top end. I thnk if you are just duning, the 40.5 keihin is the way to roll. Now, as for the alky......everyone gets alky mixed up with battery acid.....and thats not the case. it will not eat aluminum...You do use about twice as much alky to gas. you will need a fuel pump, depending on if you have a billet bowl, and what kinda riding you are doing. for just duning, stick with gas. Alky and oil do seperate depending on what oil you use. We run REDLINE ALKY PREMIX. it is different from your regular redline oil. THE TUFF IS AWESOME. i have heard of guys not even purging when they use it, but i always do. Alky on the other hand does gum up....kinda turns to a milky white chalk.... so it is important to keep your carb clean.
