Was going to go with the RK QA (-1) kit with gold chain OR the RK OEM kit with gold, but have a few concerns:

-Is there a significant increase in accel or just a decent noticeable one? Aka is it worth it?
-I've been told the speedo will be off by about 10%? What's that translate to in regards to miles travelled vs clocked and actual speed vs clocked?
-Most importantly, what's the jump in RPM at freeway cruising speeds with the dropped tooth?

Also, spotted the RK QA kit with gold chain for $149 online, is this the best I can do?

 

1) It's a noticeable increase, but nothing super dramatic. You won't be doing stand up wheelies every time you're a little hard on the gas.

2) The mileage will also be off by 10%. So if you changed it, then went 500 miles, you only went 450 miles.

3) I don't remember the difference, but I did -1/+1, and run at 7k @ 74 MPH.

 

Double post, not sure why... Move along.

 

Thanks man, just checked out your bike in the repaint thread, pretty sick
