Fuel pump problem solved
I got reminded of this recently and thought you might find it funny -
When I was 19 & bought my first streetbike (the 750 turbo) it did not run. I didn't know anything & the dealer admitted he'd never worked on one. After 3 months of him not fixing it I took it home & figured out the fuel pump wasn't.
Kaw wanted $400 for a new one (they're over 500 now) and the breakers wanted half that.
I took my bad pump to the auto parts store (Pep Boys), asked the guy if he had anything close to which he scratched his head and said here as he handed me a BorgWarner fuel pump catalog. The first half of the catalog was photo's & part #'s, the second half was part #'s with specs. I'd find a pic that looked close then see if the specs matched what I needed (50psi).
I still have that bike and for the last 17 yrs it's been running just fine on a '79 Cadillac Eldorado fuel pump that cost me a whopping $100 and was made in the good ole USA. Direct bolt in.
I bought one last year for my other bike too. They're still just over a hundred bucks but it looks like they come from China now.
