How to hook up your motor and use fat rear tire [ Coaster brake Arm Mod ]



Brake arm modification

I was waiting until I needed to remove my rear wheel so I could photograph my brake arm modification.(I did my install before I knew about this GREAT forum or I would have taken progress pics.) Any way today I pulled my rear wheel to adjust the bearings, and while I was at it, I took photos.

To make a long story short, I'll say that is is nice having a metal cutting band saw and a MIG welder.

All I did was cut the brake arm off so that the axle end fit inside the (opened) hole in the motor sprocket, over lapped it and welded it back together.Oh yeah I also counter sunk the bolt holes in the sprocket.

Ratz! Well I tried several times to post photos but it wouldn't work.
