Hi all, I'm making a little progress on the bike....
I will sort some pictures at some point.
I've given the whole bike a proper clean up, & managed to pull the injectors out of the bike.
Wowzers! they were really stuck in!
They were incredibly rusty old things.
I've carefully sanded down the rusty outsides of the injectors, and painted them so they shouldn't re-rust. Also cleaned the plastic parts carefully, along with the electrical connectors with contact cleaner.
I've cleaned out the injectors using a small 9v battery and then squirting high pressure injector cleaner through to unblock them. (all 3 were blocked)
I did that about 6-8 times on each injector, until they squirted consistently the same level.
As I said earlier i'd pulled out the fuel pump and bench tested it. It was busted!
I've since then replaced the Fuel pump, internal fuel lines and fuel filter. Along with the rubber gasket around the fuel level sender.
Then added fresh fuel to the tank. re-assembled as much of the bike as I could, then I wired up the bike to a battery and turned it over. It ran for 30 seconds or so.
Since then I've not gotten it to start up though, which is odd as the pump is running, electrics are good, spark was present last time I checked and fuel pressure is good to the injectors, with the injectors having been cleaned...I'm going to try pulling the spark plugs to check them again, they were sparking fine, but I just want to be sure. And I'll also pull the injectors again to make sure they're not clogged back up again... I may need to buy new ones if they are?
Would you recommend original spec injectors or an alternative like the 4 hole jobbies?
