Front sprocket

[Str8up]

I'm sorry I have to ask this but I'm not much of a wrench turner. Is changing the front sprocket something easily done myself? If so, I would like to lower the RPM's at cruising speed a touch and have the stock one on my 07 BA. Should I go with an 18 or a 19 tooth. Any help is greatly appreciated.

yes...its easy enough. Your 07 has an 18t so youll want a 19t.

Remove cover.
Remove nut holding on front sprocket.
Loosen rear tire.
Loosen adjusters.
Slide rear wheel forward loosening chain around front sprocket.
Swap sprocket and do everything in reverse.

Oh, and make sure you have all the torque specs.

I have a '09 Speedmaster. it came with a 18 & 42 tooth. I changed to a 17 tooth. Max 15 minute job! Difference is night and day. 70mph cruise is another 300-400 rpm. No big deal. The added acceleration is well worth it!
