As I read what is highlighted the first thing that came to my mind was Exile Choppers. Have you checked w/them?

Thanks Gary, yes I did. Russel's site says he makes on to fit with electric start, but check it out!
OB15 'electric start' oilbag, 15" width, 7" diameter, 5.5"x3.7"x4.7" deep battery box $699
OB15 has clearance on the underside to clear the electric start. Both ends are fully round, but some clearancing of the lower left side of the oilbag may be necessary to clear the starter nose on your primary. This part of the oilbag contains no oil and can simply be filed into shape for a perfect fit for your project. Oilbags are internally plumbed allowing all three lines to exit at the lower rear right-side of the bag, perfect for running the lines under the transmission end cover to the oil-pump. From left to right (of bike) the outlets are RETURN, FEED, VENT. Oilbags are supplied in a ready-to-paint raw state.
Additional charge to polish oilbag $40
612089 Oilbag mounting bushings (4) $25
492700 Outlet fittings, straight (3) $15
58-1322 Yuasa YTX20HL-BS -fits OB15 $99

This is an extremely low budget build. For that $$$, I'll live with a Horseshoe Tank!

Hoist!
