Injector Weight/Brand Recommendations, 2013 Super Glide
Hi all,
I have a 2013 Super Glide (96) with a DK 636 intake, MagnaFlow F-Bomb 2-into-1, and Accel On-Plug coils. Engine internals stock. Electronics stock (although probably a tuner at some point).
I'm looking for recommendations on injector flow rate and what brand to buy. When I bought the bike a few years ago, the stock injectors were bad, so I replaced them with 5.4gm/sec injectors from Twin Tec. The bike sat again while paint and other work was done and the injectors are gummed up again. I might try to resurrect them, but I'm looking for feedback about weight/brand before attempting that.
Thoughts?
Chris

You mean a larger bore throttle body? The intake should flow more air than the original, but the throttle body is still OE.

What TC said. Higher flow injectors give too rich a mixture with stock ECM, throttle body, and narrow band sensors. Even if you adjust the tune and add wide band sensors the higher fuel flow injectors will just not pulse as long without a larger bore throttle body to increase the mixture flow as well. Even then some head work may be needed to allow the flow to enter the combustion chamber.

I see. What about the suspicion that the factory installs lower flow rate injectors to meet emissions requirements? Any influence there?
I still have the OE injectors, but suspect that one is dead. I'll try energizing them and see if they actuate.

You have at least 2/3 of a stage 1 since you're not sure if there is/has been a tuner on the bike. Stage 1 setups will perform very well with stock injectors. Before you start second guessing the factory engineering you should probably get a good tuner and go from there. Make sure you're getting as much as possible with your mods, and I have a feeling you'll get more power that way rather than experimenting.
