[@jonthelamb4549]

That cylinder sleeve is probably from detonation witch is mainly caused by low octane fuel. I might also be wrong but I’m pretty confident

[@supertedogpriken]

was thinking the same thing. Detonation damage. But i think the fuel "quality" could be low because of way to much oil. All that oil that kept running down from the power valve, and the sparkplug being all black and oily. same with the cylinder head, thick coating of burnt oil....

This is why we always raced YZs back in the day. The guys who ran RMs were always having to tear into the engines and do major stuff like re-sleeving the cylinders. We would just do a top end every 8-10 races and they were always in great shape.

Ol' Joe loves his dirtbikes. Great looking cycle, now let's tear it apart! 2Vinney is excited, smells lots of Gravy Train coming his way Love the diagnostics. Custom Air Filter? Where can i get one of those? Why not commercial (big) coffee filters?

[@beaker89825]

I had a '70s Yamaha YZ80 that had a pin in the piston ring groove to keep the ring from rotating. That pin came out and the ring rotated until the gap was in the exhaust port. That caused the cylinder to wear badly at one side of the exhaust port. In my case it was easy to see because the pin was embedded in the top of the piston. For your stuck hydraulic hose check out the Captain Kleeman video named "Blown Hoses and Rotted Cab - Gaining Ground on the Backhoe Rebuild" around the 50 second mark. He uses a hammer drill to vibrate and loosen the fitting. Love your videos!

I would definitely consider a bobcat or case skidsteer. You can get over the tire metal tracks that will definitely help with traction. And they are pretty common and easy to find parts for.

[@GapRecordingsNamibia]

Hey Joe, so, there are a few good comments under the section, I most certainly would second a Boro scope especially when going to view a bike that won't start or has no compression, it may help with diagnosing costlier repairs up front and could help negotiate a better price....

The Tak as we use to call them 15-20yrs ago is a badass skid steer. The TL series with the rubber tracks are a beast in sandy soil and out perform most CATs and Bobcats due to the weight differences and power displacement. I use to own 2 and grew up on the beach and did a many of beach sand pushes around ocean front houses without the slightest struggle. $150 per hour 10hrs a day was our rate back then to move sand away from homes and it was a money maker.

Heads up on that year, I have 2000 modle which is the same bike. The spark plugs are a special type as the ground is not welded as the engine frequency will loosen the weld and you will destroy the cylinder.

[@danstump3686]

@@Bert805b R6918B is about $36 at Autozone. When the ground electrode on BR8ES and BR9ES fails due to the severe vibration it bounces around leaving indentations in the cylinder head and the top of the piston. If your lucky it will blow out the port - if not it gets stuck between cyl and piston and wipes out the engine.

The split in the piston was around on the exhaust side. Isn’t the locator pin on the intake side? So either the locator pic came out, allowing the ring to spin around or the ring was installed without and regard for the locator pin

[@chrishanlon6550]

Great videos. Your page gives me so much confidence to try and fix my own break downs.

[@robh3267]

One of the first things you should always check when buying a used dirt bike is the air filter and that is the reason why this bike has no compression, I've never liked 2 stroke engine designs that use a single piston ring, the thicker ring has a tendency to generate more frictional heat because of the larger surface contact area with the cylinder, also that cylinder shouldn't have a sleeve, it should have a Nikasil coated cylinder which does a much better job of handling the heat, using a Steele sleeve is a cheap alternative to having the cylinder recoated but they don't usually last, judging by the air filter you can bet the suspension internals are quite hammered also, to get this bike back to the level of performance it's capable of it's going to cost more than you paid for it, that air filter or the lack there of tells you for the most part everything you need to know about this bike, good luck with this project, these older 2 strokes are getting hard to find parts for which makes the parts quite expensive.

[@billhenry7833]

You are telling all this to a guy who rebuilds three a week…

[@bmarcstrail]

I suggest getting a Toro Dingo or Bobcat MT 55 mini skid. Lots of attachments.

[@adrianm.2043]

Regarding skid steer If you can get to it with a punch in an SDS drill with rotary stop or an air hammer you could try hammering on the flats of the nuts of the hose, that might loosen them enough for a spanner to undo them. Its a trick I learned from Clint of C&C Equipment who is another or my favourite KZbinrs. Love your video's, always interesting.

One reason you might have a hard time with taking the hose off is because it might be under pressure. You might want to turn the machine on not running and move the levers to release the pressure.

[@greenstreak750]

I had a RM 250 do the same thing yours did. Turns out it was not a standard size bore and the bigger piston size interfered with the power valve. Bike ran great and then it just died and no compression. Mine took a small chunk of the top of the piston off on the exhaust size. The power valve needs to be relieved a little bit to work with the larger piston.

[@jksynergy311]

at 28:26 there is a ?broken? brass nipple in the carb. Look into what detonation is. Thats what it does to the metal on the top of cylinders/heads/pistons. Like the top if your cylinder. It is very common on 2 strokes. Also, doesnt it look like the power valve hit? Then cracked the cylinder?

For the one wondering what happened The ring gap is normally located over a cylinder part without any port. In that case the gap was not put over the piston locator pin or the ring was too lose and rotated. This result in the open edge of the ring catching the cylinder bore opening

[@TheEvilive]

send the cylinder to power seal USA. or sometimes even local dealerships can re-sleeve cylinders

[@brianpiper3188]

My advice on the hydraulic line isn't conventional, but I hit the wrench with a hammer in extreme cases. It's a bit risky, but my experience has been that such extremes tend to require replacing more parts anyway.
