Please resume Fireballing?.

Still trying to get my parts back from NC. They don't return my phone calls. 

[Richard Ebersole]

Count me in too...would love to buy one of your performance head for my Enfield ?

[High On Octane]

Any updates Ace?

Latest update.
I got all my parts and stuff from NC. That is the end of that era.

We are working on getting a new CAD program done, modeled on one of the existing heads. This is estimated to take a month or so. Then we will seek manufacturing again.

I have a couple sets of the rockers and some other parts in the box of stuff from NC.

So, we are going to try to pull this together once again.

That sounds promising, I can't believe the trials you have been through.

[ace.cafe]

First step, digital scan.

I've been on and off following this thread for a while. Don't know if I heard what the numbers were as far as added horsepower and torque to a GT with the stage 1 Performance Kit installed. With the installation of the new heads, what other engine modifications need to be done?

The available dyno graphs are posted somewhere in this thread, or Otto's thread, Mevocgt's thread.

Basically, with the head added and no cams, it's about 7hp more than a Stage 1 kit. Stage 1 is about 25hp, and our head added gives about 32.5hp. I  can't remember the tq figure. With the cams it's about 36hp/36tq.
This all comes below the factory 5500rpm rev limit. Tq curve is real flat and comes up high real early. Rides well.

Still working on getting mfg back on line. A lot of tribulations have occured, losing mfg several times and having to start up fresh each time. Still plugging away.

Sounds promising.

Some news.

Programming is still progressing, and we are very appreciative for the efforts of our friend who is contributing his time and talents to the project.

Guaire is also now involved in sales and marketing and website activities. When you see his postings about Ace parts for sale, it is legit.

One of the latest user reports includes a power increase which is causing repeated clutch slipping at anything over 5500 rpm, after some inlet tract mods. The factory clutch just cannot hold the power in this stage of tune. We are looking at solutions for improving clutch holding. Then a dyno run will be scheduled to see exactly how much power increase is actually there now.

Here is something we have been experimenting with.
 

New hardened cam spindles, roller cam bearings, and hardened cam races. Now a full roller valve train from cams to valves.

It drastically reduces the hated valve train noise. Quieter than a KTM or modern Triumph now.
Also helps with the valve train strength which is very helpful with the high lift and valve spring force with our high performance head kit.

We will have some dyno data on all the developments forthcoming when we can.

ace.cafe -- are these cam spindles, bearings and races compatible with the 500cc UCE and Peter's C5 cams?  I just purchased a 2010 C5 for Peter (and GHG?) to use as a test bed for his piston, valve, etc plus crankshaft alignment upgrades and would like to incorporate both the 500cc and 535cc worlds when possible.  As I've stated before my goal is comfortable running in the 45-65mph range on suburban and rural including mountain surface roads.  I have the BMW for when I want a freeway cruiser.

I carefully considered your head, a beautiful piece of work and I really enjoy looking at your pictures, but decided to retain the stock exterior looks of the 500cc UCE.

Compatibility with any UCE model. The cams must be modified with the new races.

As of this moment,  we have no pricing or release date. Still in testing.

Thank you.

We will also be testing it with the Carberry plate.
