Help with BCB EFI Throttle Linkage

[TOOLMAN]

Initially I just hooked up the throttle cable and realized there was no way the cable was going to get me from idle all the way to WOT. So then, I decided to do Viperwolf's lovely progressive pulley setup and I still can't get the range from idle to WOT. Should I just be reserved to the fact that I can't get to WOT, or is there something I'm doing wrong? Bigger pulley perhaps (I used an 1-1/2")? I'm kind of stuck.

Keep in mind the TB isn't a finished product. I still need to get the helper return spring.

Is the travel restricted or does it not have enough return spring pressure?

are you able to cut the cable a bit to get WOT and then adjust the pulley for full closed?

No travel restrictions. I doesn't have the return pressure yet because I don't have the return spring yet.

The way it sits, the pedal is in it's most upright position I can get it and the pulley is adjusted all the way out from the TB. If I cut the cable any more it would essentially shorten the throw, correct? I think what I'm trying to achieve is a longer throw (thus the need for a larger pulley?). Tell me if I'm not thinking about this correctly. I was never any good at trigonometry. Calculus, on the other hand...

Bigger pulley and take the slack out of the cable.

This is basically the pulley I bought.

I'll go try a bigger one tonight. Along with the return spring. That should get the slack out of the cable that's shown. The TB is slightly open in pic because that spring isn't there yet. Didn't know which spring to get when I was at the store last night. After measuring, it should be ~3.5".

I have the adjustment slot cut in the TB arm like you have.

Thanks guys for the input!

2" Pulley seemed to nearly do the trick. It gets to about 85-90% of WOT. I think this will at least get me going.

Did you cut any part of the cable? I had to cut at least an inch off mine.

Oh yeah. That was actually my third cable. 1/16" cable at HD is .26/foot.

Now cut a little off the cable, maybe 1/4", then move the pulley in until the throttle closes with the pedal at rest. Repeat as necessary to get full throttle.

Cool. Will probably tune that after I get it running. Thanks Phil!
