I had a second 295 cylinder built this year for ice racing. My first was broad 110 olney, I put a ton of hours on it no problem. My new jug was a 295 110 olney mid high with a ported piston. I just wanted more of a top end screamer for the ice/dunes this year. I had the bike out 2 times and it was nothing but problems. Pv shaft has tons of slop and wont hold a seal because of it. The spring mounts by the exhaust flange were about wore through in 2 spots and about to break off. 2 striped out bolt holes. Head flange was wore and I would of had to use silicone to seal the pipe. The best was after 2-4 hours the cylinder cracked at both exhaust bridges and ate the piston to hell. I noticed this when you would start the bike it was pressurizing the coolant system and when you would rev the bike cooolant would puke out the overflow tube. Bike still had compression and ran but ive never been able to lean the bike out like I should of. Burning coolant = lean conditons.
Anyways I ripped the jug off today after not beeing able to ride yestrerday and im sending it off to Gorr. My ice riding season is short so this is a major downer. I have a spare yz250 but its stock bore and low mid ported for the woods so ill be going slow till I get my race bike back together. Im shure gorr will make this right ive delt with him for years.
I started this post to cuss out you who have sent in clapped out core cylinders to gorr and not informed him of the problems they had. I ended up with somebody clapped out core they sent in and its a killer. I know for a fact I sent him a cylinder that was mint and had less then 2 hours on it from new that a friend sold me.
Ive delt with gorr for years he always makes things right.
The killer of it all is he tells me Sunday when he answered the phone. Yes he picks up on Sunday. He wont have head gaskets for 2 weeks and I gave my last new one to my buddy when I sold him my other 295 jug. So my race bike is down for 2 + weeks ouch.
Talked to Gorr this morning hes sending out a new cylinder today. He said I shouold have it by Monday. Gorr tells me the new 295 cylinders hes starting to make are iron sleeved now for realiability. He is sending me the new designed piston as well with better oiling holes.
He explained why there is a backorder in head gaskets. Gorr is in the process of redesigning his head gaskets so they can not be put on upside down or backwards. Hes adding more rubber coating to them so they seal better.
This is why people are experiacing delays or shortages in parts coming from eric.
This is why I olney trust gorr to do work for me. Always improving his product and I dont think anybody would of had the turn around time that he did getting me new parts to get my race bike back running again. He recieved my crap 295 jug wendsday in the mail and a new 295 jug, piston, gaskets, and 2 new heads are getting shipped out to me Friday. Top notch service. He said 295 kits are beeing made for hondas verry soon. Now that hes lining the cylinders with an iron sleeve for the 295's just about any 2 stroke can be bored out to a 295 and be reliable.
He also said hes been dyno testing 295 kits and the dep pipe was the best performer for his 295 so far. He said 295 are made to work best with a stock pipe. He said a 300 pipe wouldnt have to be made unless you had a stroker crank thats were the pipe timing would be thrown off. Hes sending me a head gasket also out of his reserve stash also so I can get back to racing the bike. He said the new head gaskets will be in in a week most likely..
This is why eric is above all after he makes enoufgh and revises his kits 295 kits will be as reliable if not more then a stock bore.
:bonk: to eric hes always raising the bar.....

Eric did tell me people have been testing 500 silancers as higher flowing then most 250 silancers you can buy. It might be worth it to play around with a 500 silancer to see how hard it is to adapt to a yz. You can use all the power in the world on the ice spining a studded lined rear wheel on the ice that gets insane traction realy tames a bike out.
I was just about to try a bills shorty on my dep pipe before the top end crapped out. I do like mid high 295 with wr gears. For every gear I pulled most 4 strokes were shifting twice. Bike was tapped at about 90 with 14/48. The bike was slowly becoming easy to kick so I think I rode the bike for 2 hours with a cracked cylinder and still went fast.

Wow... I'm bummed to hear that. I just can't get my head around an iron liner.

+1 I hated the old days. I always looked a NicaSil as a God send.

I'm would assume he is plating the liner to eliminate wear.....

Suprised to hear about the iron sleeving. I talked to him the other month and he was still sending them to get coated. I was always under the impression he was against sleeving. I had a powervalve let loose on my cylinder last year, destroyed my piston but my cylinder did not have one scratch in it.

Im assuming he will still plate the sleeve. I just hope it runs for more then 2-3 hours so I can ride the tar out of it.

It should. You must've gotten a bad cylinder. I have well over 100 hours on my cylinder and its still in perfect condition. Sometimes he lets shit slip, but you always know he will make good of it.

I had over 200 hours on my 1st 295 jug and never 1 problem. He always makes things right. I think thats jug # 9 ive sent into him and ive had him rebuild 3 full engines too before back in the day when I was first getting into bikes. I had problems with a 144 jug back in the day too but hes always made things right.

So is the steel linner plated? I was going to do the 295 kit, now I don't know. I didn't know there was a reliablity issues with the 295.

I'm not sure on the lining but Eric's plating work is extremely good. I'm sitting at 160 hours with no issues. I've actually stretched my piston change intervals with the 295 pistons from 50-75 hours and everything has always looked good inside. I'm 240lbs and am on it hard most of that time. Very impressed to say the least.

Is anyone running the 295 kit with a stroked crank? I asked Eric about it today and he suggested 3mm. I'm thinking between that and the step up to race gas required to run it might be pretty nice.

Did he suggest building one for you or just dropping in a modded crank & rod yourself?
Changes to the porting?
What about connecting rod length?
Cylinder spacer?

I thought about building a YZ stroker crank using a longer KTM rod.
Either CNC a chromoly crank, or weld & modify a stock one.

Crankworks is local for me and do awesome work so I would have them do the crank +3mm or +4mm and any mods to the bottom half. I'm due for a bottom end pretty soon so while I'm at it throw the wr gears in. I would then send the cylinder back to Eric for porting and Head mods.

The only thing that is a hold up for me is running race gas. I guess with a stroked crank there just isn't enough room to keep the compression lower.
The thing is the bike is plenty of engine everywhere but the dunes. Actually its plenty of power there to but a little more can never hurt in the sand.

I may just stick with a straight rebuild and buy a 500af for dunes and cinders and use the 295 for desert and occasional track use.

Apparently a few guys have stroked it without any negative effect on vibrations.

Just read that e.s.r. is developing a 325cc power valved cylinder and head for the yz.Gonna call them today.

Yes the new jug I installed yesterday had a steel sleeve in it. It was also the fist time I used his new piston, That has better oiling and is now coated. I wouldnt worry about reliability. The last jug I got was clearly a lemon. Eric had new parts to me in a couple days no charge.
Eric told me if you stroke the 295 you would have to build a custom pipe also because the port timing would be off to that of a stock pipe. As far as I know nobody builds a pipe to suit this.

Is the new jug sleeved and then plated?

i just received my 295 kit from EG today and it is NOT sleeved.

the new style coated piston with TIN coated rings are a work of art. it's a shame to hide them inside the motor.

let the games begin!
