Chinese Walbro

[avalonea]

Be careful of the old walbro copies. We had always used bosch 040's for all our cars ( fyi, my and my mate have had several track only cars, plus both have/had highly modified street cars ) . Although we had a pump die on the dyno so we replaced it with a walbro copy ( as its all we could get quickly and we were competing the next day ) .

The pump worked brilliantly for about 6 months, then i noticed the car heating up a bit. I slapped on the wideband to find it was running lean up top, Turns out the old pump didnâ€t just burn out and stop working. It had started to die slowly .

This concerned me greatly. if a pump burns out and stops working. thatâ€s one thing, you can replace it after the tow home. Although running a engine lean can do way more serious damage. (Especially in a turbo application, and big money spent on internals )

I learnt a while ago : do it cheap, do it twice.

Thanks for the advice. I'd say even the original American Walbro pumps are now made in China. Seen a Buell the other day, it was supposed to have an original American Walbro in it. New bike. Stuffed after 12000kms ! At the end of the day, I may only need the stock pump that's already in the K8, either that or fit something like an external Aeromotive. 12 injector K8, 1441s a small motor, 1580s more like it Blackzook
