I am wanting to add some more power to my scoot and been thinking about a 107 kit. Here is where I am undecided:

Do I spend the money to do the T-man stage 3 or 4 kit or just do the Fuel Moto kit with the stock heads? Yes, I know the two kits are drastically different, but I cannot decide if I am opening a can of worms by doing this. Meaning would I be sacrificing reliability going to the more radical combo?

I am thinking about buying some take-off heads to send to them (T-man)so I won't be down too long and I have emailed them about thier kit and having to send my cylinders to them. The kit says it has Nikasil cylinders, but I am not sure if that is just the liners or the actual cylinders?

Of course, money is a concern, but I don't mind spending it up front to do it right.

Can you guys give me your opinions? Is there any other kits you guys would do instead? Am I going to have to upgrade the intake and TB for these mods? Bigger injectors? Upgrade the clutch pack?

The bike is a 2011 Rocker. I have VH 2 into 2, high flow ac, and a PCV.

I know what I want to do, but thought I would ask what others would recommend, since this is my first HD and I thought I could learn from some more seasoned riders past experiences.

 

I've noticed opinions are a dime a dozen around here so prepare yourself for hearing it all.

I know I've done alot of sole searching since I went the route I did with my 103 upgrade.

Knowing what I know now and having no desire to split my cases for a 110+ ci build, I wish I had gone with a 107 upgrade. Doing it now is difficult to justify the expense of gaining 4 cubes and a small gain in power.

But I have done the research, for no other reason other than to make 100% certain its more money I am willing to spend for that extra power. It is.....!

There a number of good builders out there. Some hang around this forum answering our questions.

If I had it to do over again, I would do a 107 with heads done by either TMan or Hillside. I like the Nikasil cylinders, rather than honing 96 bored cylinders. I like TMan's head work and larger valves...stage III or IV whatever. Whatever pistons TMan suggests for the CR needed. A Tman cam...probably the 625 or 650 depending on your type of riding style. An HPI 54 mm tb with 5.3 g/s injectors and one of the auto-tuners out there.

If you want max HP/Torque, I'd ditch your Vance and Hines and get a D&D Fat Cat 2 into 1 system. It may not be the exact sound your looking for but no one will have a faster 107. Oh, and take care of the clutch. Add a heavier spring.

 

I really like the VH exhaust and didn't really want to get into changing the injectors/tb, but I guess that is something i need to decide.

I guess I just need to pick a supplier and get their recommendation on which route to take.

I don't mind losing a few hp's for the exhaust. Are we talking big loss? I mean 4-5hp I don't care, but 15-20 would suck.

 

JMHO but there is a lot to be said for boring seasoned cylinders. I know Hillside will bore your cylinders and fit some Wiseco pistons, not sure if Tman offers that service. Nikasil is the cylinder lining and it was all the rage a while back until Rev Performance started having problems. Actually, I believe TMan's kit include Rev Performance cylinders. From what I have read, that's all behind them and nikasil is not a bad word anymore.

Most important thing is to pay attention to how you ride and decide when/where you want the power and work toward a combination of components that will deliver the power when/where you want it.

The other thing to remember is that most folks have a tendency to over do things and the spend more money than necessary gains at the margin and the cost per foot pound of torque goes up exponentially. You can build a strong runner with minimal head work if the heads are "blue printed"; a lot of porting points things toward higher HP numbers. Long duration, hi lift cams same same; bigger is definitely more expensive but not that much better that a good baseline build.

 

The Fuel Moto kit seems to be a great value..you can get your heads done by Hillside..they know how to make power with this combo

and it even works pretty darn good with the stock heads

Nikasill has had some issues , I understand it had more to do with the ring pack..
I am in the middle of a 107 build myself, and decided to go with the CP pistons an woods 555, because I got a great deal on a set of pistons..I dont think you can go wrong either way...

 

A 107" engine can be brought to hot-rod level, or kept in check for very strong touring duty as well.
One of our 5 different cylinder head packages, combined with the proper cam grind, will expose all the potential of the 107"er to it's fullest, while still maintaining great reliability, for either a lighter weight Dyna street fighter, or a fully loaded Road Glide combo.
Our Wiesco's with your cylinders bored,(88-98", 96-107") have proven themselves for over 3 1/2 years now, to be, a go-to set-up.
We do not sell you folks pieces/parts that you don't need, but our combinations, surrounded by the products we reccomend/supply, most certainly un-cork, what is in it.
Feel free to contact us.
Thanks,
Scott

 

...my 96" stock cylinders and heads arrived at Hillside yesterday. Getting Stage III heads, 107/Wiseco & TW555's plus a couple of other parts. Stock TB/injectors and a Fatcat w/a std louvered baffle are waiting. Now if the 25+" inches of snow on the ground would ever melt....
