Engine and Bottom End / Re: Coolant Leak - ESR E2 363 PV Cylinder

« on: May 03, 2026, 08:27:11 AM »

Interesting. I don't think the sleeve cuts into the water jacket. Can you see the crack in the water jacket? Not sure if you can clean it and get epoxy in there. Would be best to try and epoxy the crack from both sides. Good luck with the race.

Best regards

Thanks, Jason!

The leaks were at the cylinder and the sleeve seam at the transfer ports and the exhaust port.

It survived! Got the holeshot, 3rd in Vet class, and 11th overall of 78 riders.

After I get everything cleaned up, I?ll be able to better assess the situation. It didn?t get overly hot during the race, so that?s good news. I?ve got until June 13th before the next race to figure out a better solution. Or maybe it?s good enough and I?ll be able to keep running it?

Huge shoutout to Blake at DBC Racing for all the last minute help!!

Thank you for all of the feedback. I was able to pressurize the cylinder and find the leak with some Windex. It took awhile, but I finally found it. There's some very minor leaking at the cylinder exhaust ports where it meets the sleeve. It's not an ideal fix, but since the cylinder is on its final bore, I added some epoxy to the leak site in hopes that it fixes it. We'll see. My goal is to get it back together in time for a race on Saturday. Fingers-crossed it works.

Engine and Bottom End / Coolant Leak - ESR E2 363 PV Cylinder

Anyone have any luck with ESR cylinder repair?

Had what I thought was a leaking head oring. After pressure testing the coolant system, found out that I was getting coolant leaks from the exhaust side of the cylinder. I found this crack when inspecting the cylinder. 

Could this crack cause the coolant leaks? Does anyone have any experience or tips to repair it?

Wanted / Re: Round/Aftermarket Frame Coil Mount

« on: February 14, 2025, 09:31:49 AM »

Actually, I just found this pic of what looks to be an ESR coil mount plate with a rubber strap to mount it to the frame. I already have the ESR OEM frame mount with plate, so I think I'll just try to find a rubber strap to mount it to the round frame.

Wanted / Round/Aftermarket Frame Coil Mount

I’m trying to track down some pieces for my Arens frame swap.

I’ll need a round tube/aftermarket frame coil mount; does anyone have one that they’d like to part with?

Thank you,
Wes

Do you mind if I ask what you paid?   I’m considering selling my Arens frame.  You can message me if you don’t want to broadcast it to the public.

$3,200 shipped. The shipping quote that he shared with me was ~$250.

Congratulations on the new purchase.  Hoping to see a build thread.

By chance have you heard anything from John Arens?  I have not.  It’s been years since Arens said he was going to build frames.

Joe

Thank you! I’ve been looking for a while. I’ve gotten sick of having to tear down and repair the cracks on my OEM frame. It turns out that racing is hard on stuff, especially 40 year old stuff.

I’ll try to do a build thread, if I can find the time. It’ll be more of a frame swap than a full rebuild, though.

John was the chairman for D-14 XC last year. I talked to him at a couple MOXC/D-14 combined races about making frames again, selfishly for me but in general as well. It’s the same old response. He’s got a few other projects to finish up and then he might be making some more. I was hoping to be able to play the racing series angle and have an in. I wouldn’t hold your breath.

John is the 2024 chairman for the D14 ATV XC series here in MI. I’ll be seeing him at future combined MOXC/D-14 races. I’ll try to ask him about the status of the frames when I see him next. I want one, too😊

Hi Guys,

I’m looking to do some upgrades before the upcoming race season.

Like the title says, I’m looking for an Afco radiator and an IMS 4 gal dry break tank setup.

Please let me know if you have either available.

Thanks,

Wow, those are beautiful! No surprise, though, being that they’re from Sonny.

I haven’t measured either of them, nor do I know how to.

All I know is how my Zeel is currently configured: 50.0* static angle and 31.3* lobe length.

Are your base settings from DRW the same as mine?
