Re: '75 suzuki gt250...Now onto fuel injection UPDATE 2/23

About the Map sensor, that's what I thought as well, the pulses from the ports being open at the same time would make for some interesting graphs. In the manual it specified using AlphaN when using a large duration cam, similar symptoms to what 2 strokes have to deal with. I wasn't planning on using one, but now that I have one I gave it a second thought. Many pages ago in this thread I posted my wideband o2 sensor that I tried out for a few runs. I'll definately have it hooked up and will make tuning go along very quickly. And, of course as soon as its dialed in it gets plugged. I've already got the coils and connectors shipped to me, so I guess I'm already going down that road. I'm looking forward to only having the points being used as a low amperage switch with no condenser. As far as injector flow goes, I have no idea. I saw how well the banshee idles and reved and assumed that it will at least get me started.
Of course, another update. I must have made some very wrong calculations when making my first set of intake adapters, because there is no way the tb's will fit on with the fuel rail up top. However, they do fit on "upside down" but that would make the installation of the fuel rail difficult.
So, I scrapped that idea and ended up with version II:
With an angle of 25 degrees, it isn't very steep and clears my oil lines by about an 1/8". I decided to bolt on the adapters to make sure they work before doing all the work drilling the big hole in the center.
I also found out that my unifilters are the same size and fit on the tb's
I took another look at modifying the existing fuel rail and have come up with some ideas based off of the same banshee thread. Hopefully I can get the tb spacers made, long bolts cut and rethreaded, and the fuel rail on the tb's this weekend. Thanks, Joe
