What do you guys think of the CT racing cylinders? I've been in contact with Allen about a cylinder that is getting repaired for a friend but after looking at the website I was leaning towards their 330 kit that is $1500 and that includes a complete rebuild of the crank, new bearing and seals, check everything in the bottomend, machine the cases and reassemble the engine. Cylinder is ported for what ever its going to be used for with proper dome. It seems like a pretty good deal or is there a better option? ESR, LRD ???
-
they are good but know that your getting a cookie cutter set up my org 310 came from ct and i had to do extensive porting to get it where i wanted it. price sounds good though
-
that is a great price.

I bought a blank cylinder from CT and had it drop shipped to Neil for a full port job. I had the crank work done locally.
Is the rebuild of the crank just labor or does it includes parts? Same thing for the bottom end, will everything be replaced or just checked out?
-
This is exactly what I got from Allen...
Yes for that price you send us your bottom end, we split it, inspect it, and re-build the crank main bearings and seals are included, with the exception of the water pump seal, we don't go through the water pump, as there is nothing to see, it's either good or leaking. Cutting cases and all is included we assemble the top end onto your bottom end. Cylinder is fully ported, and race ready. Compression is set to what you are willing to burn for fuel.

If you want to know about CT there is plenty of bad publicity out there to knaw on. CT's cylinders are made by ProX(if i remember correctly, basically a ProX with nikasil plating), CT's porting is lack luster and nothing special in my eyes equal to the esr clean up porting.
if you want a big bore with basic bolt it together horsepower/performance levels thats what you will get. if you want to maximize the performance/horsepower of the setup your paying for i recommend to continue searching for your porter/builder there are many to choose from.

whats the price of just a cylinder?

Motofool,
thank you and that's why i'm asking. I may just have Neil port a cylinder for me and just be done with it. I would love to have a BB but I'm starting to feel that my best bang for the buck will be Neil
John,
I believe it's a $1000 for the cylinder. I haven't checked ESR prices to compare.
-
Blank cylinder was 900 (330) when I got mine a few years back.
Also, it sounds like it's just crank bearings and seals, not all throughout the bottom end. If you were gonna send CT your whole motor, why not just send it to Neil? You'll get a better bang for your buck and not some cookie cutter porting. He spends 2-3 hours a day for a few days porting a cylinder. The guy simply loves 2 strokes and working on them. Just talk to him on the phone and you'll realize.
And if you're gonna spend that much, go all the way and get it done right. That's just my opinion Joe!
-
I agree Fear and will probably just go down that road and be done with it. I know I will be pleased with the results just The sales pitch sounded good from CT! LOL
-
if my choices were limited to Niel or CT there would be no choice.
last time i had a cylinder done i went with an ESR (blank no porting no boring)
500$ was the special at that time.
450$ port job on the cylinder
dont remember the dome cutting price.
put in +4mm crank and new bearings and seals and gasket kit and new clutch plates and was ready to go.
Hybrid assembled and ported/bored/machined this setup and its almost more fun then the PUMA as it just works great
-
imo I would go with the esr cyl and put the saved money toward whatever else you want to do.
Example, if you are going to have neil port what you get you can get an esr and hotrods 4mil for the ct prox cost....
-
Excellent info guys and thank you so much!
This may be a stupid question but who is Hybrid?
-
Just wondering who is Neil that all of you are talking about? ESR?

Neil Pritchard, C-Leigh Racing, you can find him on the other site or facebook. I had him port my stock cylinder and it runs great, and he's also a great guy to talk too as he knows 250R's.
-
allen at ct is real slow to get your parts back if you have in house work done

guess he/they have no website

If you are planning on MX or similar with it, CT is a good choice. You will get a very tractable power from whatever he sends you, will have good torque numbers HP is not real high on his priority list similar to LRD/LED if you get to talking to them. Allen will build you a engine that is not flashy but puts power to the ground and doesn't wear you out, if that's not what you are after I would continue shopping. One should also keep in mind that when they look at a CT Pro X it probably isn't altered much considering he was the designer of it, my LRD Pro X looks very plain also for the record but runs nothing like a unported cylinder.

I have one of the first 40 310jugs that did not need a spacerplate and was unported.I was never unhappy with the power,only unhappy with how long it takes to get your stuff back when they do shop work.a year ago I sent my jug to them when I finaly got it back the piston would not even slide all the way thru the bore
-

He surely does not. He's an ol timer. I only found him through the forums myself. And I'll tell ya, my 330 that he ported runs like an f'n raped ape. She cooks for an mx style port let me tell ya!!
-
I have 2 CT power valve cylinders and my turn around time was actually rather fast for sending a cylinder from California and also I sent him another one I had and had him set it up with a new piston and it was just as quick. I have talked extensively with Allen and he is very knowledgable. His "porting" is lack luster unless you really talk with HIM and make sure he does the porting. I would recommend him for sure, more so then ESR, but then again I wouldn't recommend ESR to anyone. My opinion so people don't jump on me.
-
Im glad your happy with him.I was not and will never use him again.he is real sharp and knows how to make the sale,we do have to give him credit because him and la sleeve got the big bore thing off the ground .pretty much everybody I know in vegas has the same complaints that I do

Are you referring to CT Fred?

Just got of the phone with CT and apparently the cylinder I sent them has a Rotax power valve and they said it's on old design and to upgrade to their new style. Isn't the rotax PV a fairly good design if I remember correctly? The upgrade is $175 and not sure if it's worth it. I'm not sure if this PV works as the engine came in pieces but it looked OK. I do need a gasket it for it so if i decided to run the rotax PV then where do i get parts?
-
I believe the rotax were the good pv's.

Not sure about older/newer Rotax setups, you might do some investigation. My biggest concern with a Rotax is the fact that it is exposed somewhat, I've got one of those little Duncan bonnets for it but it fits less than great. The CT one is sealed up like an ESR one I believe, I like that idea better but as far as performance I have no idea how they compare. I'm happy with my Rotax, just pees juice all over, no idea what they may have changed in the guts and how that would effect it though. CT has been good with service for me, sent a cylinder and I have sent a few counter balancers there and everything went quickly and the work was good, my experiences have been good but other have apparently had bad ones.

You should be able to get the PV parts at your local Ski Doo dealer if you know the part number. Service Honda also sells them. The part number for the gasket is 420250239. The Rotax PV is a robust and time tested design are they updating to a newer Rotax PV or their own design?
-
They updated to their own design.
