Post subject: Dellorto Kit Problems  Posted: Fri May 26, 2006 9:59 pm |

I just installed a Dellorto PHF 36 kits on my 1990 750 Sport and the bike is running terrible. Starts up and idles fine, but hesitates, stumbles, lacks power, backfires and eventually the RPMs drop and the engine dies.
I've removed the fuel pump and am letting the carbs be feed fuel by gravity from the tank. The pump just overflowed the bowls everytime. The fuel is getting to the carbs though.
I don't understand this. Can anyone help?

I just fitted a Mikuni set.
I kept the returnline intact
So I:
- kept the fuel pump
- kept the T-split in the fuel line
- 1 direction to the carburettors
- 1 direction to the Fueltank (returnline)
Engine starts good, Idels good, runs good.
Used a special needle and Jet Kit of Dynojet for a 750 Ducati.
