Yup, Same one I am working with. The intake is dry so the added plenum volume shouldn't hurt anything if the throttle body is relocated to the side and down. Stay tuned.
Do you have a pic of the engine? I think that is the same engine I am using on the OBW project. It looks like I will be relocating the throttle body with a custom 3d printed adapter to make some more vertical space.
Some general suggestions/observations after having my lo-rider flatty for a decent amount of time....
Getting the powertrain up for a flat belly is work, but worth it. The flatter the belly profile the better when you are building low. The powertrain is going to have to be mounted almost flat...
