I bought skean1 hybrid Sphinx motor and can tell you it is a beast. Great top and mid but still has bottom end as well. Hydrid would be good option for you.

id send it to Pete at Hybrid, Neil is more of a MX guy and not sure how much he's done with CPI cylinders. Don't short on the bottom end and transmission. Do it rite the first time, it's not fun looking down and seeing pieces of 2nd gear laying in the sand. I have a Sphynx built by K&T(not my first choice) but I bought it 2nd hand. Gonna run Pwk 40.5 and LED 350G pipe. I had 2 Pumas 1 built by Pete and 1 built by Packard. Those 2 are the only ones I'd use for a CPI Cylinder.

I wouldn't say mx by no mean...Neil (Neil Pritchard),(c-Leigh) has done 4 engines/ cylinders for me.. his engines perform a certain way... like a signature of him speaking through his work or something ..and he can defiantly do what a customer asks for.... I'm not sure but I think I have the only cp cylinder Neil will ever do from what he said..And it's not cause he can't because my puma mid range ported was 51 ft pounds of torque and 71hp on the last dyno pull, way rich no smaller jets to lean out and make another pull . It's blowed out Arlen's billet gears and a set of oem cryo treated,magna flux,micro polished gears as well on a tt track  .we all know trannys are a problem..This not a drag cylinder was not looking to squeeze ever ounce out of it..it was built for torque and pull and it's exactly what I ordered... Neil don't like building the cp stuff do to cost. He likes the 2 stoke to be cheap to fix and build and not rob the customer out of thousands like a 4 poke does... I'm sure he will slide in here soon..cp stuff is just so costly to build and time consuming with shipping and all the stuff that comes with these cylinders,but as stated many excellent builders out ther for cp cylinders...

My hybrid engineering Sphinx pulled a jerry hall and klemm lt 500 by a quad length. The jerry hall 500 was dyno'd at 75hp on Jerrys dyno. Petes motors pull hard.

I believe that it might be the other Neil some of you are thinking about. Cant remember his last name, but he does a lot of drag stuff like Pete does. Was a member the other day asking about him, he hadnt seen or heard from him in a while & was wondering what was up.

kb250r is correct, he has the 1 & only CPI cylinder I'll ever touch.
My reason, I've been in 2 strokes for many years & as I went through those years, I got gut feeling on how some things operated & some things produced I just didnt have a good feeling about it. Its kinda like all these new 4 pokers, has something to do with it, by them being so high priced off the floor & for parts & up keep.
When you design a 2 stroke product, your not dealing with the main stream everyday used type of machines sitting on the show room floor, so consideration needs to be made for who it might be will use your products.
With our ol 250Rs, the price of some of these things produced today, the moneys just not there from the regular consumer. Granted there are some owners with deep pockets, but it is a slim few. So, why produce a product that will take every penny a regular person has.
Now I'm not knocking the CPI stuff in any way, I consider it to the highest quality you can buy, but, how many ways can you design a 2 stroke cylinder & make it into something never ever produced any years before it. There are some projects out there though, that are breaking new ground in design. In the end though, they will probably be in the to high priced range for many to afford.
With the 4 pokes on the market today & the parts offered, high as they are, it sets a sight that some will try to match up to & it just cant be, not for a 2 stroke world of today.

Getting back on the transmissions, any of the hollow OEM gears in the TRX250R transmission will be the failing point of all of them. There may be some stock Rs transmissions out there that are holding up, but if you really check into them close, they are probably not binding those rear tires up grabbing every inch of traction they can get. Check out just about any drag quad, long swingarm & real high speed wheel spin. You bind a quad down, short swingarm like in TT racing, placing those rear tires close as you can under that riders butt & your hunting for all the traction you can find to push that rider & quad forward. Wheel spin in TT racing, = going to the back of the pack.
Out of all that, you can see the strain on all those gears & the job that they have to do & stay alive.
If all the gears were solid, wider & thicker, they probably could stand a lot more HP thrown to them, but what most of us have, old, beat up & weak, we are lucky any of them are still in the cases on the first pull or lap.

kb250r racing his trike in TT, after the build, busted a set of checked close for cracks, cryo hardened, back cut & polished gears. Next he got the ones LED offers & busted those, so what is a 250R owner to do. It does look like the Baldwin gears over the years must be the best, but I have no clue who produced them.

Jerry hall(HPR) out of Glendale, az is great with two strokes. I don't think he's built too many cpi cylinders tho. Give Pete or him a call your be good.

They are in the making.  There has been a medical issue come up and put us two weeks behind.  But I assure you they will be coming soon.

I always liked the idea of needle bearings instead of bushings under the gears. was this a consideration with the new batch ?
to much power is almost enough
