It's a 1940 Indian Chief,74 cubic inch (1200cc) flathead 42degree V twin, with a three speed gearbox.
It has a hand gear change on the right hand side of the tank and a foot clutch on the left foot board (which operates the opposite way round to the one on my Shovel Electraglide). The throttle is on the left and the right twistgrip controls the advance and retard. The front brake is in the conventional position but is mainly ornamental.
The front suspension is by leaf with trailing links which is pretty good and the rear is by springs above and below the axle bracket resulting in about inch and half of travel. I think the rear springs were developed(?) as one in the eye for arch rivals HD who soldiered on with rigid rear ends for some years after.
I've tried to keep mine pretty original but because I intend to ride it a lot I have carried out a few mods although I still have the standard parts. I have replaced the 6V generator with a 12v alternator from a Kubota dump truck and a CV carb from HD.
I have finished running it in now and it and its loosening up a treat cruising nicely at around 65 mph, very relaxing.
