The test of time.
Today is 12/18/2012 and on 12/23 I will be taking the old girl to the dealer for a new 750
My final thoughts are as follows.
Best single upgrade you can have. (clutch kit)
1. All the factory lag is gone and the bike just go's. It isnt that the bike is faster it is just quick.
2. This upgrade has been very good to me with over 1,000 miles on it I have had ZERO issues.
3. I have enjoyed this mod so much that next time I will buy mods 1-5 and spend the 640 dollars vs the 200 or so that I spent the first time.

I have not been on a King 750 so I am no sure how long I will ride it stock.
I am hoping that trading in 493 cc's for 723 will be enough for now.

I created this post because I could not find a decent one that talked about the mod and gave some seat of the pants info.
If you read it all thanks and yes it was all worth it.
