750 Frame help

Vierkan had cut the frame tubes that run from horizontally from seatpan to the front downtubes, then discovered that the frame section at the front of seatpan section was weak and had porous welds. So Nguyễn the weldor stopped by to fix things up. He smoothed off the old welds and cleaned off the paint.


Then down to business.


All welded up.


We didn't care, but Nguyễn wanted things to look good.


Now to stiffen to the back end a bit. The seat support behind the shock mounts will be coming off soon too. A little pipe right here should do.




Tacked in place.


Nguyễn does the full weld to the tube.

750 wired and starter working

Okay, still working on a wiring. The key switch is place and wired with the 30 amp breaker behind it, mounted to a existing frame tab.

Ground wire to the frame, to green wire from the harness, and to yellow/red for the starter switch.


12V+ one to the starter relay, and one through the circuit breaker and to the key switch.

Here's the circuit breaker.

Starter button.

Back of the starter button. It takes a ground to low side of the starter relay. The key switch is the high side of the relay.

Seems to work. Vierkan does the honors.

750 Oil lines revisited

Okay we didn't have the oil lines correct and that was causing out oil tank cap to blow off. Big thank to FXRSBIGBORE on the Shovelhead.us board. This is the correct oil line set-up.




We had the bottom crankcase vent going to the air and not connected to the tank.

750 fires on all four, now

Okay, we couldn't get spark to the inside cylinders. We tried every kind of troubleshoot only to be more confused about it. We swamped the condensors to see if one was bad. That's when Bierkan realized that the green wire to the condensor on the suspect point set was on the outside connector and not the inside connector. He swapped the wires and now there's a spark on all four. Not sure when it got crosswired, but we should be running next week.
