What is the best fuel injector cleaner for a older sportbike?

Answer 1

BG 44K, it's a little pricy but it's the only one that not just oil and fuel, don't know what I could say to make you take my word for it other than I've been working on cars for years and I put it in all my cars and bikes and I heard of it through a very experienced mechanic.

they have it at advanced auto parts stores.

Answer 2

I vote for Sea Foam.  Cleans all the varnish out, right away.

Answer 3

Chevron "Techron"

Should be able to find it at the big box auto stores no problem, or BMW dealers sell it too
