Hi guys
I was reading tbat ESR & CT Racing started producing cylinder again. Is that any true to that.

Thank you Paul

Hey Paul, yes cylinders are slowly trickling back.  ESR has had a few batches (CEO cylinders) lately but they sell fast.  CT was working on releasing  some as was Duncan racing.  And then we have CP industries…I heard that guys have been waiting on the Puma cylinders (many months)….I’ll reply back next week as I will be calling CP to make  an order.

Esr never stopped.  He’s just been held up by a bad cnc machine and foundry issues.  It seems he’s got a handful of 363s available here and there lately.  They are up on the site and then shortly taken down.  Must be selling a handful at a time.  I believe lynx and Sphynx are available.

I was just on duncan site. They are saying they will have cylinders spring/ summer

ESR has recently had batches of CEO PV 310s and 363s; you just have to check their website for availability.  Note that the 310s are the latest E2B cylinder, whereas the 363s are the E2. I picked up one of the 363s several weeks ago now, which I was surprised that it was the E2 cylinder when it arrived. He had it clearly marked as the E2 on his website, but I overlooked that with my excitement of the availability when purchasing.

Eddie is setting up a 350 CEO for me.  Not sure if it’s gonna be E2 or E2b.  E2b has the taller studs on the intake and the water flowing into the front instead of the back.  Correct?

[bushwesl]

Yep, exactly. Here’s a couple of pics I found of the E2 and the E2B cylinders for comparison.

If you think about the change in the cooling port location it makes sense. Honda even changed the cr500 cylinder to this cooling port patern.

Here is mine.  Eddie is shipping it soon.

That's awesome. You should really enjoy it
