Trying to verify what size injectors are in my bike. Previous owner, who had big bore kit installed can’t tell me any details. I went in today to install SE Extreme 64mm manifold and pulled injectors to see what size, but can’t find any info regarding make or size. #64137 on injector, but can’t find anything with that number. Any of you who did the Stage 3 or 4 kits with 5.5 SE injectors notice or make note of a number on injector, like on pics below?

I saw this post and got curious. Did some research and the number that matches your injector to what I could find was #0280158413 that was stamped on HD Screaming Eagle injectors. Its the 5.5 High Flow part #27400040. Do a search thread as I think its been brought up before. Hope this helps.

 

Thanks - I could not find any numbers on pics of the SE 5.5 injectors, and have never seen HD give any details on their parts descriptions. Appreciate the help. I went ahead and ordered some Fuel Moto 6.3 injectors.

 

Those FM injectors should work out great for you. Let us know how the build ends up.
