Hey guys I'm new here and was hoping you could help us out,
My girlfriends bike is a 2001 CBR600F4I, I just put a 15 tooth front sprocket on and was wondering what the best speedo box would be the best for it.
Also does her bike have the plug in it for the cct? I mean the plug in the end that a bolt could be threaded into?
Also looking for ideas on a undertail for her bike.
thanks very much guys/gals

 

im curious why did you replace the front sprocket and nothing else ?

 

you have 2 choices in speedo correction- yellow box and Speedo healer.

it appears that most people lean towards the speedo healer as it recalibrates dead nuts on, I
have read that the yellow box is not as accurate as the speedo healer.

i dont know about the cct

and yeah did you only replace the sprocket, or did you also replace the chain and rear sprocket, but only changed the size of the front?
It is usually not a good idea to only replace one part of the chain drive. a worn chain will wear out a new sprocket, and a worn sprocket will wear out a new chain.

 

I just put a 15/46 and a new RK chain on my bike. I advise you to replace the rear sprocket and chain, otherwise you are wasting your money. In 6th gear, the speedometer is close to accurate. 1,2,3 gears its off bout 15 to 20 mph.

 

I was listing the sprocket because I wanted you guys to know I changed the gearing, of course everything is done properly, stock rear gear, new 525 chain. thanks anyways
