Can't much argue with that logic.

In all seriousness don't treat this as a 'have to get it done in a weekend' project. If you've done a top end before, sure, have at it. But as a first time doing cylinders it's not something you want to rush into. With family and kids you'll be lucky to get it apart in one weekend, then you need quiet time to check ring gaps, clean the cylinders properly, and assemble. It's different than just bolting things up.

Now that you're on the west coast consider looking into shops over there. Shipping will be a lot less and faster. My head porter is in Washington, HD Street Performance.

 

Always easy for others to spend your money. Talk to Kirby; you don't need the expense and additional labor a 117" motor involves to build a hard running 107" or a 110" with a drop in kit. I have seen some drop in kits putting 120/125 numbers and 107" motor putting up numbers in the 115/120 range. If Kirby does the cylinder work, he will set ring gaps; all you need to do is properly clean the cylinders.

 

maybe look at cam with higher lift and the later intake closing number

 

I would call Jamie at fuel moto and tell him where your'e at and where you want to go. Listen to what he tells you.

 

Well, I appreciate all the encouragement, I always know what Suede is going to say, and he does spur me on so well!

Still in this case I am looking at more of a "B" word build (read, budget). And simplicity. I've been saving for a new road bike frame (I have a beautiful bike but have been lusting over a custom frame out of Portland for years), and I'm kind of close to having the spousal unit approving if I give up the next 3 birthdays and christmas' (yes this frame is that expensive). So I really don't want to upset the proverbial apple cart!

Kirby's 107 cylinders and pistons would work well apparently and only cost about $600 plus the additional tune so think I may go that route.

 

Good luck ! I have been thinking about tearing into mine. Pretty sure I will within the next month. Taking my time , and probably missing some of next summer's riding.

 

My plan was something like this. And I started a thread about it. And now I'm building a 117"

 

Yeah, I've been watching your thread, living vicariously. I have too many expensive hobbies and sports...

 

What frame are you looking at? I was a bicycle mechanic in a former life.

 

Would talk with Jaime or Bob at Fuelmoto about what you have and what you want. I have been working with Bob on my project, which is similar to the FM 107 Hellraiser setup with a few differences. For my 107 build I am looking at 120r2 or higher numbers using the Feuling 594g cams and C-head porting services. The bottom end will ride on a S&S crankshaft with dual lefty bearings for longevity. Compression will be set pretty high with a high ccp for the cams to wake up but should still run on 93 pump gas.
