Changing Countershft Sprocket for a sidecar?
« on: August 12, 2014, 01:19:27 PM »
Does anyone recommend or have changed out their countershaft sprocket on their RE motorcycle because of the sidecar?  I have a 2012 C5 with Inder sidecar and believe it comes standard with a 17-tooth sprocket.  What are the pros and cons of going to a 16-tooth sprocket?  I plan to keep the sidecar on all the time.  I want to change out the standard chain soon and what to do the sprocket also if it is advisable.  Thanks in advance for your valuable input.

here's note from Kevin from another post:  "Dropping the front sprocket by a tooth is a good idea. The rear sprocket/drum really can't be changed. It is the same 1930's design"

I would recommend dropping a tooth on the front sprocket, it will put less stress on the motor and give you a little better acceleration, assuming you never ride it much faster than 55 mph.  Dan, if I remember correctly you live in Colorado not fat from me?   ???   If so I can give you a hand doing the sprocket change if you'd like.  I've had my primary cover off a few times now.

Hello, I am new to the forum.  Just bought an Inder sidecar to install on a 2012 military c5.  Sounds like the unit you have.  Can you post a couple of photos that show your installation and hardware placement.  I have zero references for installation that give good clear directions.
Thanks in advance.
