spray starting fluid where the JB weld is while holding the throttle at a steady RPM and see if it revs higher due to a leak and sucking air...

[@minnesotatomcat]

Yes I was gonna suggest the same, I use that trick on vehicles all the time to find vacuum leaks. I’d spray it around the carb too, could be a crack in the intake boot or anything else, that’s a pretty old bike now.

[@ajc5370]

Great idea and quite honestly is a pretty easy fix to depending. A good TIG welder can button it up quick if it's not terrible

[@tuberNunya]

The intake doesn't suck air from the crankcase, Mr Mechanic.

[@oriancunningham]

@@tuberNunya youre trolling, a bad seal, or small crack in the case would cause a vacuum leak

[@PurpleMonkeyWaffle]

If it was sucking in air then fatting the jets would have helped. He went all the way down to 130 and still same problem.

[@dougaranda6187]

Since re-jetting didn’t have much effect, I wouldn’t rule out electrical just yet. Just because the spark plug checker shows a plug is ok, that doesn’t mean the other components aren’t breaking down.

[@anthonyjacobs8773]

Excatly what I was thinking. Does that look like a tape job coming from the stator wire?

[@2strokeme64]

Cracked stator plate, throws it out of time at higher rpm, figured this out on a banshee, only after countless hours fukin with dual carbs....

[@PurpleMonkeyWaffle]

I'm thinking the flywheel has gone bad. He needs to check if there is fuel in the exhaust. If so the ignition system is faulty.

[@PurpleMonkeyWaffle]

@@anthonyjacobs8773 I recently had a loose coil wire its more like a complete loss of power than a backfire then FULL power then no power, backfire etc. I've also had bad flywheel which was very similar to this.

[@stevefirth6472]

Before you tear anything down, check the power valve. That's what it sounds like to me.

Yep, gotta be the ol’ power valve. Free her up. (I have no idea, just agreeing)

[@OldmanADV]

check pipe , to make sure there is no obstruction ! I had this issue with a 2001 cr250

[@DavidPhelps-du1mx]

Could bent places in pipe have caused an airflow restriction? Spark arrestor plugged?

[@HenkkaEuro]

@@DavidPhelps-du1mxdepends on where on the pipe its located

[@bruceprosser4283]

Agree 110%.. When you pulled the plug the first time and it was wet, I said pull the pipe and check for oil residue. I have had to clear out a CR 250R pipe by burning it out with a propane torch. It did the trick. Peace

[@Yz4Life]

And re pack the silencer!!! Every 20 hours is the spec in most manuals, the packing degrades and gets soaked with oil inhibiting the top end of the power band

[@HenkkaEuro]

@@Yz4Life fax

[@steveaustin1984]

Take your pick of which to tackle first: 1. Crank seal 2. Power valve 3. JB weld

[@stkyfngrszmooth]

I'd go with the power valve first only because I had this same exact issue with my '90 YZ 125. Turned out the mechanic reassembled the bike with the power valve backward. After fixing the issue, it was business as usual, with the bike revving out with zero hindrance.

[@michaelesposito6678]

3 first 2 second tear down 3rd

[@Proxiir]

Could definitely be a sticking power valve or air leak.

[@louieuribe3343]

Leak down test… that will narrow it down quickly. All the carb adjusting in the world won’t fix the issue if there’s an air leak. Good luck and keep up the great work and content.

[@brendans7489]

definitely a crank seal i think, my 250r did the same thing.

[@JonRoundtree-mu5gb]

Mid range bog=power valve sticking or misadjusted. Set the power valves up right and try a 170-175 jet. You should solve it that way.

[@ronsherfy6291]

Do a leak down test first and while doing so spray soapy water around the jb weld case repair. Check power valve for excessive carbon build up or possibly worn or broken power valve. Silencer may need cleaned and re packed. Clean up all ground contact points on the frame. Had a bike years ago with a bad port job done by a goon that acted just like this. Rule out the above mentioned before tearing it down. Good Luck! It’s a good looking bike!

[@staygold902]

I've said that many times. It's critical to leak test 2 strokes. He's not once done one on video. Never

[@jakeowens1770]

Word up on the power valves. Had that same problem. Don't think its vacuum case issue as the plug would be white

[@staygold902]

@@jakeowens1770 he has no idea what the plug is actually reading he didn't do a plug chop

[@jakeowens1770]

@staygold902 if it had vacuum leak, it would run better with more fuel and higher main jet.

[@staygold902]

@jakeowens1770 depends how bad it's leaking and he only tried one larger jet It's nothing to go to the hardware store and fab up a leak tester. Fresh rebuild should have it done every time. He's never done one in his life. It's necessary. You can't rule out something you haven't even checked. But I agree something could be going wrong in the power valves too. Might have to check lol

[@arrobrewer2730]

I'm amazed at how many times you miss 2nd 😊

Never cared for the "95" purple. I had a new 94, which was gorgeous. Either way, this was a nice score on your behalf.👍🏼 With some patience, this bike will return a hefty sum at some point. Detail the hell out of it and keep it in the showroom condition that it is.

[@ajc5370]

[@Wantobefit]

You beat me to another bike, had this one saved on Market Place myself and was pondering about purchasing. Awesome find and enjoy the videos.

[@TheHowitz]

Man i'm stoked you're making this video. I have a 97 that has a similar problem. I replaced the right side crank seal with no improvement.

[@dixoncider7256]

Just saw this comment a couple of lines below yours, "My buddy's yz 250 sounded like that, and to find out it was a partially clogged silencer"

[@dixoncider7256]

Read through all these video comments. Lots of great information. Here is another one, "Before you tear anything down, check the power valve. That's what it sounds like to me"

[@benburton8463]

I know its not the crack seal. The bike would rev all over the place like high low tick overs takes ages for revs to drop down. Power valve or stator or coil, even a bad cdi

[@Deathtrap617]

Pro circuit pipes work amazing on these bikes, I raced cr250’s from 1990 to 2008 the I switched to Yamaha 450’s

[@mikenielsen8738]

whats the diffrent between 250 - and 450 topspeed ? Iam 186 cm 150 kg and i didnt no is 250 enough power for my weight the bike is for fun and speeding and a bit enduro

[@jeffmckc2081]

Those spark checker can be a simple check but they have no combustion chamber pressure on them so don't rely on it completely or it can bite you

[@bret44]

First thought when you pulled it off was the crank seals, they get hard and brittle after 20 years on a 2T. All that junk around the flywheel made me think it was blowing premix out on that side. I didn’t see any oil coming out the muffler so I don’t think it is the rhs seal. I guess it could be the power valve not opening.

[@harrybosch5720]

Yeah, Id think your chasing your tail with the jetting, I suspect air ingression thru the crank seals or that crack in the crankcase... somewhere its getting in. These faults are real buggers to solve but great when you nail it. At least you can shut the garage door on it and dont have to ride it home. Have fun!!

[@jasonblankenagel5412]

Since the bog is at the mid to upper RPM's only, It would likely be an obstruction in air flow. Check Power valves to make sure they are fully opening at the higher RPM. Also, make sure your pipe and muffler are clear.

[@dixoncider7256]

👍

[@Dismantledgarage]

I had a 93 same exact bike alot of good times on that machine!!

[@jbro238]

I just bought a 03 cr250 with bad bog! It ended up being the power valves were adjusted wrong. the servo motor wasnt opening the ports for mine at the right time. If this ytear has that motor, definitely worth checking! It still has the slightest bog at low rpm so i will be doing a carb tuning like this in the near future. great video, hope you find the cause on this bike, these things EAT!

[@karl6823]

I would go for the crank seals, after checking the power valves

[@kootenaycat]

Check the power valves for sure, they need regular cleaning anyways. But my money is on a bad coil, it's breaking down at high rpm. If it had an air leak from that JB weld or flywheel side crank seal you'd think smaller main jet would make it worse. Looking forward to seeing the fix! Retired auto mechanic here but recently got into small engine stuff and enjoying the change!

[@julianp4787]

JB Weld on cranckcase is letting in air. The higher the revs, the more it sucks in, the more lean the mix :)

[@bwfreel]

That’s what I thought, JB weld is a clue for sure

[@greathornedowl3644]

Ding Ding Ding - I think that is the right answer

[@Aint9sk8rd9]

My 89 CR250 had a very similar issue and it was the power valves not working correctly. The power valves are a different setup on this but it's worth looking into.

[@zachfarkash6430]

Love my 89CR250R great bike

[@truthsetsyoufree77]

I reckon power valve sticking as its bogged hard at the beginning. I've had that happen to two yz 125's. If not could be the JB weld, or crank seals.

[@rickashea2114]

Did you check that ground where the frame was painted

[@PaulHigginbothamSr]

If I had one a small hole would be much better than a crack, which will need drill at the ends to make sure it doesn't travel laterally.

[@qacomputers3344]

yep, the same thing when I repair cast water lines,, drill a hole on each side of the crack, tap the pipe till the crack reaches the holes, then clamp it...

[@CezaryAkakios]

When the jetting wasn't having much effect I was back to thinking ignition. Maybe check the gaps in the magneto pickups, the magnets in the flywheel, coil resistance, ignition module, etc. I could see one of those having an RPM dependent failure, such that it works fine below a certain RPM but then breaks up at higher.

[@TheBababa420]

See what s up the JB weld.

[@thebigguy8306]

IMHO always a RED FLAG - run away

[@Larry-w1r]

Why can't jb weld fix it?

I also have a 91 125 which had a similar bog as your bike tested everything changed stator cdi exhaust system crank seals and put a new pwk carb on her still had bog. Only thing left to change was coil and ht cap I changed them the bog was gone. Love your channel man hope this helps 🛵💨

[@chrisharriman9017]

I've dealt with that I'm in outboard business see it alot above 1/2 loses or weakens spark

[@nickgruber2593]

Wow a CR! Nice 👍

[@crazychad2720]

2 stroke dirtbike go-to checklist for me when it comes to performance issues. *Jetting/Spark Plug *Reeds *Powervalve issue/dirty *Crank Seals -stator side will cause air to be. sucked in, causing lean condition. -clutch side will suck trans fluid into crank cavity making bike run very rich Usually one of these is always the cause, of a consistent performance issue. If it's intermittent, especially once warmed up, usually electrical. I see you touched these basis and took all the right steps.

[@97delkron]

doesn't seem like crank seals. no weird hanging idle or excessive smoking. my first thought was old fuel. but i think you used fresh fuel? i would remove exhaust and verify no blockage then check power valves. they may be gummed up and sticking. if those check out, i would look at ignition system. maybe swap out coil. i have had weird coil issues in the past where bike would start and idle fine but break up at high rpm. change coil and no more issue.

[@rs5001988]

I agree with some other posters, check exhaust for an obstruction before a teardown. Never hurts to check it.

[@tylerhosner9011]

I had a 96 kx250 that ran identical to that. It ended up being the power valves not functioning properly

[@jetenginethrust863]

I have a suspicion the bog might have something to do with the JB Welded cracked engine case or a bad CDI Ignition or even a sheared off Woodruff key on the rotor/flywheel. Also check the ignition plug wire real good while running with the lights off and make sure it's not grounding out to the frame or engine. FYI I'm a 59 yr old FAA Certificated Airframe & Powerplant Mechanic since 1992 and have been repairing engines of many types from a young age approx. 7yrs old and I have 2 CR 500's for about 20yrs. 👍

[@PurpleMonkeyWaffle]

Bog can be lean, rich, bad reeds, burning other fluids or bad ignition. Idle down sounded lean, but it runs worse when fatting the mains?🤔And better when thinning? Sounds like a lean idle circuit but a rich main. An air leak would be helped by fatting the jets not thinning so I don't think you have an air leak but you need to do a leak down test to confirm. Leak down tests are a MUST! The needle clip is stock at second from top but is it the correct needle? Plugs looked rich but not too rich but they were way too wet. I think you have an ignition problem or the carb itself is faulty. I had one on my Yamaha TZR 250 that ended up being the flywheel/rotor. EDIIT: Check the exhaust pipe for fuel. If you have fuel in the pipe your ignition system is the problem. Its not firing as often as it should and fuel is getting thrown out the exhaust port. Also yes the PV could be the problem too. Check that the pully was not put in backwards. Its common with the Yamaha RZ350.

[@sammycoppens5470]

I would check the idle jet (the brass thing the needle moves through), since you are changing jetting and reacts in a weird way, I believe it is still related to jetting but most things you already checked. I once forgot to put it back in and had some similar issues.

[@larryburrough3024]

I'm going with the power valve. Seen it before on the Honda. Also had a similar issue with a Cat snowmobile. Pretty much similar symptoms. Both were dirty/sticking power valves.

[@wiggie7420]

Power valve stuck shut

[@charlesgoss3521]

Not for this occasion, but for hard starting,and especially big bores, tilt the bike on it's side until you see gas overflow, put the bike in gear and rock it back and forth. Fuel is sucked into the engine and really helps promote firing. 2 strokes only, unless you want cam chain and valve timing problems. As a long term CR500 Honda owner and rider in all weather conditions, this really saves your right leg and all of it's components.

[@dezrtrat702]

There may be an issue with the power valve. Cole seely posted a video about a week ago on 94 cr250 with power valve issues and shows that you can check it running with the cover off. His channel is Cole Seely. And I remember this being common in the 90s with the Hondas Update: Cole’s newest video shows his mechanic explain a little about the power valve at like 3-4 minutes in.

[@AlAmantea]

Power valves, Joe... clean and adjust!!! Could also be a bad spring on the valves. Then go back to the stock jetting.

[@johngarris8463]

Love your show man beautiful Honda keeping ripping

[@Thuddster]

Clean pipe and silencer. Repack silencer. Revert back to stock main jet and needle setting. Test ride. If symptoms persist, check for case leaks (JB weld area is sus). There may still be a hairline crack in the case, maybe do a magnaflux check if/when you end up replacing the case seals...FWIW, back in the day I worked on a TZ that was missing like your CR at high rpm. Checked and changed damn near everything, eventually found a hairline crack that leaked only at high RPM due to case flex/distortion above ~8k revs. That was are real beech to diagnose.

[@davidcorder95]

Oh heck yeah I loved that bike same age as me

[@paulmarriott8645]

I had a 350jobs and as I remember it had to have a special plug with a resistor to stop it from interference with the power valve motor. Plug number had an R at the end.

[@PaulvanNieuwenhuyzen]

I once had a Yamaha 200 2 stroke 2 cylinder, as a boy of 14/15 year old, and at one point you had a mechanism on the ignition system with, when the engine made more rpm, the spark was made earlier by adjusting the moment that the points were opening. The ignition time was changing with more or less RPM. Now did I buy a complete little set and I just put it on, and the engine did run but did not have the higher rpm anymore. Same as with your bike. I also changed the carburetor, the exhaust pipes, and so on. He had more rpm when I made it leaner, but no power on the top.... I sold the thing before I found that. Then I got a Yamaha YZ250 from I think from around 1985, and there I got the same problem when I got trouble with the engine. The top of that Ignition changer was put on exactly the wrong way, so the ignition time didn't change but stayed the same all time. Again bought it in original parts of Yamaha and I think the did the same thing again: assembled it exactly wrong. I took the top of and turned it 180, so the time changed by more RPM and the problem was gone. It is a bit silly explained, but I am dutch and not very well know with the technical terms in English. I think it is about timing...

[@TroyRosenbaugh]

Kinda clanky kicking it over..

[@gmeister07]

My first thought when you first revved the bike in your driveway is power valves. If the bike bogs down right around the RPM it would be hitting the power band while riding and then that is confirmed through your test rides, that would be the first thing I tear down and check.

[@TroyRosenbaugh]

Beautiful bike, you really find nice ones...

[@geordimaul5380]

My thoughts is an air leak from the airbox boot or carb to engine boot. Maybe just swap the carb out Looking forward to the next vid and the solution

Before even watching the whole video, it is apparently the stock reed valve assembly. So the reeds are probably bad. Full carb rebuild and clean. Then check the Power valve when running to see if it's opening properly.

It's acting like an old 1964 jeep I had, when coil started to fail. While cold, it ran fine until it warmed up. As soon as the coil heated up, the spark just scattered. Replace the coil, she ran like a dream.

[@ngneer999]

Suggestion from someone who hasn't worked on these since the 1970s. Ignition coil could be having troubles at the higher RPMs. I assume everything is solid stage now but if possible, swap out the ignition system or come up with a way to test it.

[@zackk695]

This has me puzzled! You were in the gas coming towards us and a few times it sounded so incredible. I’m thinking the ignition is now not keeping up, maybe the stator or a rubber boot intake with fine cracks maybe

Crank seals on those things are notorious for sucking air. I think it’s worth the time and then at least you know! Put a new piston in with a set of reeds the FMF pipe would be a decent upgrade as well!

Sounds like the ignition system is breaking down as the revs rise. Try another coil or ign box. Put a timing light on it and check that the electronic advance has 3 definite steps and isn't splattering over a range of positions. Other stuff to check. 1 carboned up exhaust port and chamber/ silencer, 2 primary drive side crank seal.

[@dennisbrooks186]

U had this issue b4 on a rm125 at your parents house. Was the power valve the whole time. Deff need to check that out. I don't think it's crank seals. U would either be real smoke, or hanging idle, snappy revving from being lean. Go back to 175, 55, 1.5 turns, mid clip. Then dive into power valve and pull exhaust to make sure its not partially plugged.

A classic screwup when people replace the top end is to not get the power valve actuator pin lined up when setting the cylinder back down on the case

Its not the jetting. Could be bad cdi,Coil, stator, yes or power valve not opening. Its not crank seal. It would rev up n down very weird. Like revs stay high for long like running lean.
