1977 FLH SPROCKET___???? help
I want to get the rpms' lower at highway speeds. I want to get a small rear sprocket and a larger front sprocket.
DOes anyone know what the smallest sprocket I can get for the rear, and what the largest would be for the front?
Thanks.

You can get (I would not ) a 26 T trany sprocket and a 48 T rear wheel sprocket The 26 T trany sprocket that big will eat the inner primary starter boss (you will have to clear ) One thing about this set up No fat chicks allowed or you will never get out of the hole ! Then again this will probably mean you will never get in the hole either ! What humor !!

Yeap sqdealgeorge is right ! You have to grind some metal away for the front sprocket and burn-up the clutch to get moving.Once you are moving it will lower the rpms but is it worth it? Thats why they came out with the 5 speed in a 4 speed case 20 or so years ago!

Try a 24 front and a 49 rear. That was my combo-of-choice on my '78 FLH w the 3 speed/reverse transmission. The 24 will not tend to eat into the starter boss if the chain is kept adjusted. But it will chow down on it as soon as it's not tended to properly! We used to take a piece of steel flatbar and heat and bend to shape to put around the area. Haven't seen that in years, but the how-to is in one of the early volumes of the EasyRiders magazine Tech Tips books. The books are available from the J&P catalog, and are well worth having if you're pushing an older bike down the road.

Make it easy and go to a 49 on the rear wheel. That will get you a bit more leg, and you'll know if it works for your riding. Don't have to go into the primary removal business, either.

The baker really rocks. If you ever get one you will think you got a new bike. I have had one for 3 years...best thing I ever done to my bike!
