I may need to sell this soon and was wondering what a realistic price would be? There is considerable work done on the engine and I was wondering if it might be worth more to sell the motor separate from the other parts?
That would reduce your 60 MPH RPM's to 4531 with a 18 tooth front and a 49 tooth rear with a 18" wheel. Much more livable.
You could then install Mikes 5th gear and reduce the RPM's further to 4342 at 60 MPH. You're getting there!
By comparison, a 17/34 sprocket ratio with a 16" wheel is 4280 RPM. That's stock on an '80 to '83 Special.
Here is a modified Xcel Spreadsheet that includes a 49 tooth rear sprocket and Heidens primary gear ratio to allow you to see the RPM vs MPH for all combinations of primary gear ratios, gears and sprockets.
Just click on the numbers in the cells for front sprocket, rear sprocket, rolling distance and primary ratio to reveal pull downs to select whatever numbers you want.
Hi, Thanks for all this advice, it really helped. I've been riding the bike and think I could use a bit more help if you don't mind. I was wondering if having a custom sprocket made for my sprocket/brake sprotor setup might help? www.rebelgears.com/vintagesprockets.html I thought maybe if I had a custom one made with 46-48 teeth. I want to get as close to stock on the lower gears as I can.
