I'm gonna sample some degree of T-Man's kit "stages" to do on my 110"s. I'm not sure how much hp-chasing I want to do utlimately.
The Thumper Kit is about $2,500, including labor and shipping.
The Bottom End work is about $1,500, including labor and shipping (more for reliability and peace of mind than hp.)
The 58mm TB, roller rockers, 3-stage oil pump, and other goodies is about $3,000, including labor and shipping.
This $7,000 gets reliable 125-130hp/tq squared numbers, depending on pipe choice (and solves the majority of "issues" for the 110" in the process).
The upgrade to 124" while doing all the above is about $2,500.
This $9,500 gets reliable 135-140hp/tq squared numbers, depending on pipe choice.
My main question is... Which "stages" would you do or not do? I'm after decently big numbers with reliability. I'm also looking for the best answer to the compensator issue. Can/should I do a solid compensator? What are the options? Just pay the ~$400 total replacement cost every year/10K miles?
What else or different would anyone suggest?
Here's the info from T-Man's site:
T-Man's 110" CVO Signature Thumper Series Kit
This is our CVO 110” kit that lives on the edge. It delivers a smooth but aggressive power band throughout the power range. This is a fully CNC ported head that includes our oversized valve seats and valve size of 2.180 intake and 1.700 exhaust with a inlet opening of 1.800.
Our T-Man pistons are a must with this combination, coupled with our T-Man cam set specifically designed for this kit and you have an aggressive performance package that maintains its rideablity and durability for distance riders.
Please note that an oversized throttle body and roller rockers are needed to utilize this kit’s full potential.

To pre-empt the inevitable... I don't want to do the 120R. I don't prefer the power delivery characteristics, and there's a big $ number to complete a package. And I also don't want to pull the 110" and sell it to offset the 120R cost. I know that is a viable option, but isn't my preference overall with T-Man's bottom-end and other pricey options for durability, etc. And the 124" is tempting while everything is out and being done. It's just a money choice relative to value.
And yes, I know 115+ hp/tq squared is possible with a milder upper end build, and the lower end is not inherently necessary with such a milder build. I'm chasing bigger numbers with reliability, but there's a diminishing point of return on value of hp per $. I'm looking for opinions about how far to go based on preference and experience. There isn't necessarily a right or wrong answer, so all input is appreciated.
Thanx in advance to all.
