I thought I was the only one. When I sent my jug to Eric I was excited. Nearly 6 months went by with zero responses regarding status. I was beginning to think I got scammed or the guy died or something. My frustration and disappointment grew as I was beginning to believe I better be on the hunt for a new jug. Then finally one day I get a notification that he wants to deliver it to me via the Midwest Engine shop near my home instead of just shipping it back to me. I figured no harm, good to meet the guy. So I agree to meet him there. All seems well. Eric seemed genuine. I get home with new gaskets, "a" cylinder, a piston and rings. When I got ready to install, which was that day I realized the cylinder wasn't bored at all, and the piston was significantly incapable of fitting in that bore. So I reached out to Eric. I met him again about two weeks later for the work to be redone. At this point my faith was waivered as I am wondering about his attention detail and to a customer's paid for service.
Another three months goes by. I'm thinking I've already waiting 6 months. Why the hell isn't my long since paid work prioritized? Finally, he set a time to meet again to pick up the jug and piston/rings, etc. all seemed well. However, the piston has what I would say is too much play in the cylinder. What do I know, right? Eric is supposed to be "the man.".
I assembled the bike (100% restoration). The bike started on the 2nd kick and sounded great. The first time I took it out it blew a head gasket after 20 minutes. Got a new head gasket, installed and torqued the head as always. Back out again. I had a couple of short rides and all seemed well, but I noticed engine knock on the top-end of 2nd gear or highigher. So I pulled the head to make check the piston and cylinder. All seemed well, and spark plug was a nice Caramel brown. So I reinstalled with a new head gasket and again, torqued etc. Next ride, coolant and was gushing out of the head. That ride ended in 5 minutes. New head gasket, same deal. Another new head gasket and brand new OEM head. Still gushing coolant. Another new head gasket, and the bike just won't start. Turns out coolant is getting into the cylinder. After 8 hrs of trying everything I can to keep the coolant head leak to stop. Finally I got it. Took the bike out and it rode great for 15 minutes. I chose to stop, let it cool and check the coolant level. It was low again. I topped it off and tried restarting. Clearly the plug was being fouled again and it would not start. I checked the coolant level after a few minutes of kick starting and it was low already not having even started.
At this point I believe there is a hairline crack somewhere in the jug. I am almost certain it is not my jug. Now I have a beautiful restoration worth little as is. Can I blame Eric? I cannot for certain, but this isn't my first rodeo when it comes to restorations or top end rebuilds. All I know is that I have a jug gushing coolant into the cylinder and have had head gasket issues repeatedly, even with a new head. In fact the second head gasket was broken with pieces I know not where, likely in the case now as sometimes kicking it feels like something is getting jammed up. My guess is that because the piston is not a snug fit it is hitting the head gasket unevenly, which cause the gasket to break the 2nd replacement. Now I'm looking at a full engine rebuild again with only a few short rides. I ordered the last used jug I can find on the Internet and will make sure it is in pristine condition before installing, but hopefully it's not bored out. Another builder I follow says he's not a fan of BB kits due to unknown issues that arise. I am beginning to side with that. However, I have a Eddie Sanders 325 BB kit on my 250 and it has been fine with greater quality of work and customer service than Eric Gore and Eddie is or was just as busy with orders. At least with my 250 I can revert to my old jug if need be. I'd inquire with Eric Gore, but at this point I believe I had dealt with someone that these days lacks integrity of work and communication. So, it's not worth the headache and months of lost time if I even allowed him to do any work.
Some companies just get so big, in their mind, that it just don't matter. That pitting.... end, immediately, send it back. ZERO is acceptable. Gorr is meant to be setting the standard, that's a joke.
If I got a piston with relief holes drilled like that I wouldn't even bother emailing him, I would just file a CC charge back. Stevie Wonder could do it better after 6 beers.
Why and how would a piston ever hit a head gasket?
Do you mean the cylinder head?

I locked up my bike in 98 . I honed it my Honer kinda sucked some metal was stuck on the walls. I called his shop drove to Madison he honed it I bought a piston . I think I was there 10 minutes. I couldn’t believe how many cylinders where there shelf’s all the way around the room full of cylinders. Could’ve been exchange program cylinders.
Weird thread since he’s been retired for yrs.
He does work for a bunch of guys racing the Midwest Vintage series... Just did a modern YZ 144 for my buddy and he loves it 😎
He's been back at it for awhile. https://eric-gorr.com/
I’ve seen this happen on Harley and sport bike engines when the cylinders are over bored and a stock or wrong diameter bore head gasket is used.
Feel like I have stumbled across dirtrider.net forums
I never even got a response after my shit port job and non existent replating I was charged for from a tuner. My bank helped me get my money back, then I got a response to my email asking why I did a charge back.
Not that weird considering I started this thread in 2017....
Me and a friend got our Yz’s 144:ed many years ago.
No problems at all!
He did a 155cc big bore/stroker kit for a cr125 back in like 2011 or something like that.
I wanted his race/top end porting and head cut for race gas.
When I got the parts back the cylinder was unported and the head was cut to much since I had a 2mm squish gap with a stock base gasket.
Since I live in Sweden i was not interested in sending the parts back to him again so i just sent the parts to another tuner instead.
My first and last experience with Eric Gorr
The 144 is bored larger than the head gasket opening, which is for a 125. If the piston is hitting the head it is also hitting the gasket, which is what was causing the gasket to get destroyed.
I doubled up the gasket under the cylinder and it gives just enough space to not top out and break the gasket. If there was a correct size gasket for 144 bores that would solve the issue as well.
I can’t believe there isn’t a specific gasket for 144 kits?

Sounds like Eric got overloaded.

Plenty of us that build them use a head with o-rings instead like a VHM, or some stock heads can be modified to use O-rings.
When it comes to Honda cr125 00-07 you can’t cut groves in the head with a lathe because of the shape of the coolant ports and placement of the head bolts so you would need to use a CNC machine to do it and it instantly becomes easier to buy a aftermarket head with O-rings instead.
Cometic had a gasket kit for the big bore where the head gasket was oversized. Or maybe double up the base gasket or order a thicker one.
BINGO! All of our big bores came with Cometic gasket kits,
I was sitting in a hotel bar one night in Ohio on a business trip and ended up talking with some random dude. Eventualy me building engines came up. He asked what kind of gaskets I used, seemed like a weird question but I said Cometic, they're the best. He smiled a bit, and told me he was the founder. Had pictures on his phone of him hanging out with Carmichael, tons of race car drivers etc. Rob Gorman seemed like a really nice unassuming guy, invited me to tour the plant if I wanted but sadly I never made it over there.
HTH did I stumble into this thread?
It’s like a time warp.
Used to deal with them a lot with custom gaskets. They were top notch not only as a product but also customer service. I was desperately in need of a top end kit at one time and they said that the gaskets would be made but couldn’t guarantee on expedited delivery. Jokingly I said so if I make the drive can I just pick them up. Their response was absolutely. Long story short, my buddy was going through that area the next day and stopped by to grab them. Ended up with my gaskets, tee shirt and stickers. lol. Never had a bad experience.
He retired a few years ago. The website is used to sell parts.
I had good experiences with him (10+ cylinders).
Ive only had good experiences dealing with him. A few times I was surprised how fast my motor got back
