Fuel Pump Function Query

Just consider alignment of the pickup is probably critical....

Just consider alignment of the pickup is probably critical....

 

Point taken, however both the arm and the coil onto the arm are both straight bolt on application.. comparing the two for alignment should resolve that issue.. Thanks for pointing that out.

this kind of thing has to me always been the achilles heel of electronic ignition parts. work now, then maybe not, then maybe. And no parts house will guarantee stuff once it leaves the door. but for the most part its pretty reliable stuff. But when it goes bad, brother as you have seen it can be a snowball effect. One part goes bad, draws more juice and burns something else up and .......

New pickup coil installed. No adjustment on those, straight bolt off, bolt on and re-install everything.. Well that's making it sound TOO easy.. but it is.. a biotch to get at.. (something like doing valves)

 

The old pickup coil is deader than door shyte.. the new one metered at 222 ohms, even after soldering the connector. And the bike starts every time.. awesome.. not bad for $23 vice $150..

 

Unfortunately, though the bike starts ok, rides well (very well!), the idle is crap.. no poppping or backfire what so ever.. but at 1,000 rpm it will hold idle for a bit and then start to falter and engine dies if not attended to.... but a shot of gas keeps it humming.. but it doesn't hold.. If I set idle at 1,500 rpm then there's no probs.. it'll hold idle for quite a while.. but that's not correct.. Hmmm let's check carb synch.

 

Though I did a carb synch not long before the bike died, it was waaaay off this time. Each side was off a few notches but the two banks were way off.. Though I have it synch'd for 1,000 rpm, the idle still won't hold.. its a little better but not something I would say is good.. setting idle at 1,500 (or somewhere in between where it won't falter) gives close enough to the same readings..

 

SO, close but not quite yet.. Checked all electrical connectors, fuel, vents etc.. can't find the problem.. yet..

ok....are you using same igniter....you had the Dyna 3000 before this episode.

Then I think you tried the stock unit.
