A/F meter for bike? (Page 1/1) FieroGT42 JUL 16, 09:34 PM Motorcycles are "other cars", right? Is there an inexpensive A/F trim meter that I can throw onto a bike? I'm getting my first bike and will be doing some intake and exhaust work that affects the fuel trim. It's an older carbed engine, so I may need to re-jet and I'd like to be able to see if I'm leaning out or rich.
