Sometimes you gotta keep it simple. Some 97mm round forging pistons for Frank at ATK USA.

Here we go again, crank pins off to be heat treated. The batch had to be scrapped. Hoping to have these before Christmas.

If you plan on rebuilding your crank any time soon, order a pin kit before its too late. First batch sold before they even came in.

Making an update to our piston kits.

Thanks to the ongoing shortage of just about everything. All new piston kits will be equipped with CPs shelf ring sets only.

Nice work man

People always get surprised about what it costs to get a good ported head. Especially a Rotax head. The math says this should be making 70+ hp on a 600.

What do you guys think?

its hard to break .38 - .40 hp per cfm @ 12 INCHES , goal is maintaining a nice flat tq cure with good peak hp

I’d rather see what the torque curve looks like.

Michael does phenomenal work. He fixed my XL350 head a few years ago that HRT in Chico completely fucked up. HRT (Hansen Race Technologies) didn’t listen AT ALL, closed my chamber in to adjust the squish band, which launched my compression beyond 13to1 with new guilds and seats. It blew a hole in the head next to the valve guide to the exhaust port. Moral of my story is, don’t use word of mouth only use people such as Elliott Iverson. Saddest part when I picked up my fixed head Michael truly felt bad how much he charged me his quote “I’m sorry, but I had to fix someone else’s fuck up!”

Beautiful work.

Dyno numbers are as widely exaggerated as a mans girth. Believe what ya want to is my thought.

Got compression?

A model of some custom pistons going on a short stroke build. 13.2:1 compression on 103.1x70.4mm means a big dome, around .250". A big dome means more weight, to counter that these will receive the underhead milling to shave as much weight as possible to get to 11k rpm safely (relatively).

Another batch of parts going to a customer, just in time for next year's builds.

If you'll be needing anything CP-Carrillo for an upcoming project plan ahead. Demand is high and production can hardly keep up.

We are a CP-Carrillo distributor, dealer pricing is available to qualifying engine builders.

Working on the XL/RS600 bastard motor today. Got to a stopping point. Unfortunately, what is left to do was undone by someone else and still remains in the one single bag it came in. Time to dump it all out and figure out what goes where. ... See MoreSee Less

Does it have extended head fins?

Sometimes length is what matters most. Custom Carrillo rods for a short stroke project. One might even make it in a 676. ... See MoreSee Less

Received a batch of timing pulley pullers. These have been on backorder all year. Get them while you can.

Made in the USA!

Long awaited pistons for a customer. It always pays to have extras. Just have to wait patiently for the rods to accompany these pistons. ... See MoreSee Less
