I was going to do the FuelMoto 107" Big Bore kit but once I got into it more, I decided to change things up a bit. First, FuelMoto does great work and they have a great reputation here so its not a knock on them, I just wanted to support my local shop (Chris Rivas VTwin).

I got the bored 107" Cylinders (core exchange) from Rivas, along with some CP Pistons (10.75:1). I then decided to switch my cams from the Wood 555's to the 574 Easy Start Crane Cams (Chris "Rocket" Rivas Endorsed Cams) and the cams are all they are cracked up to be! I was afraid that with going with the 107" and the 10.75:1 pistons that my starter may burn out quickly. I felt as though my bike had a hard time starting at times with just the 555 cams in my 96" motor. With the easy starts cams, you can tell they work as advertised. The bike fires right up...even better than it did when it was a 96" with Wood 555 cams.

I also did a 2" tank lift and the deluxe option (that raises the rear part of the tank up 1/2"). I don't have pics yet but should be the weekend, just gotta clean up the scoot...she's dirty from doing the 107" build. I will post those pics here once I get them... I love the way the tank lift looks.

Here is my dyno sheet:



She runs like a raped ape.... IT'S AMAZING!!!!

Here is the post with the pics:

pretty darn good. I love my 107", it's crazysauce. Did you do your heads, too?

 

No, no headwork. I friggin love it!

 

Awesome! Glad you're happy with it.

 

Till you get restless again...

 

I'm confused, if I am reading the Crane info right those cams should only have 9.5:1 compression but you have around 10.75:1?

 

Probably a minimum compression. Like the 555 prefers more than the 9.5 CR.

 

Intake closing is so early that it makes sense to me to have a lower static compression:

 

Thanks man!

Hahaha maybe

 

I honestly have no idea. I went with what Chris, who helped designed the cam, recommended with what I was doing. I do think I remember him saying it closes earlier than the wood 555 cqm so it helps with more compression.
