Some rather fuzzy pics of my home ported throttle body.
I basically-
1. removed the ridge right in front of the throttle plate
2. epoxied the PVC/choke hole
3. smoothed and bell-mouthed the inlet to the ridge I removed
4. trimmed the screws that hold the plate to the throttle shaft
5. trimmed the throttle shaft
6. knife edged the leading edge of the throttle blade
7. finally I did the throttle stop mod.
