Title: RPM on Bullet 65
Post by: hoppyre on August 14, 2007, 12:52:04 pm

I have installed a Smith's tach on my 06 Bullet 65, stock 17 tooth c/s sprocket, Classic exhaust, S&B pancake filter, rejet carb. Engine runs at 3500rpm at 55 mph. It seems like the engine is running too hard. Is this normal, or do I need an 18 tooth sprocket?? If I change the sprocket, how much lower will the rpm be??
                                                                                           Thanks,
                                                                                            Mark

It does feel a little high when you hit 55-60mph (although the bullet speedo on my 04 65 is at least 5mph optimistic)

Here is a chart off of one of the other Bullet list-srv discussion sites:

19T
50MPH-2870 RPM
60 MPH - 3450 RPM
70 MPH - 4025 RPM
80MPH - 4600 RPM

18T
50MPH-3029 RPM
60MPH-3642 RPM
70MPH-4249 RPM
80MPH-4855 RPM

17T (stock)
50MPH-3207 RPM
60MPH-3855 RPM
70MPH-4498 RPM
80MPH-5141 RPM

Thanks alot Blowout, that is just what I needed!!!!! When I get a few more miles in her, I might go to an 18 T sprocket.

Don't the new 5 speeds come with 18 tooth sprockets?
