Another part for this series! Excited to see you back on this project

Unbelievable effort!! I have a 1989 YFM250. Managed to change a few gaskets and bit of a clean. But to tear down and rebuild, amazing 👏

It was a lot of work but it turned out pretty good I think! Thank you for that!

I've watched the whole series. Great work! I picked up an 89 moto 4 and have restored everything but the engine so far. I am really hoping you can help with a wiring question. I have what looks like an 8 to 10 guage cable with a ring terminal on each end, about 20 inches long. I am going through the manual and cannot find any reference to where it goes. Any idea?

[@ToyShopRestorations]

No idea 🤷🏻‍♂️ maybe an old winch wire?

I have to do the same engine because it won't shift right. It was running in second gear and just went into "neutral" and is now stuck between second and third gear. Won't shift up to four, and won't shift all the way down to neutral so can't start the engine either

Is the forward/reverse lever not engaged?

[@Viralvid2024]

@@ToyShopRestorations the forward/reverse lever was definitely tough to shift, but in this case I was riding slow in second gear and it just lost connection to the gears all together and ended up in false neutral. I wasn't in the middle of shifting, I was just on the throttle moving forward in second when something let go. I shut it down, and tried to downshift to restart it but couldn't get it to shift down to get the green neutral light to come on. I actually just pulled the motor yesterday and have the parts carefully organized in small groups, and don't see anything wrong or damaged in the left side where the middle gear is now exposed or the right side where the shift mechanism is. I'm now at the point where it's time to split the case but hesitant and still trying to determine if it's got anything to do with either side where I'm at now. When I try to shift it now and listen, I can hear the two gears shift up and down in the middle of the case and then silence as if whatever gears are affected are completely unattached because there's no grinding or junk rattling. No obvious metal shavings or chunks anywhere either, including in the oil that came out. Prior to this happening, I did hear a faint rattle (an occasional knock) somewhere in the case when it was running in neutral that wasn't in the top end, and may have been something in the gears near neutral, 1st, and second that almost sounded like something was loose. Any of that make any sense? I figured I'd ask you since you spent some serious time inside that engine and the diagrams both coming apart and going back together. Excellent job on this entire project by the way! I was extremely impressed with the level of detail and problem solving you put into it!

@@ToyShopRestorations also, the forward/reverse lever was engaged in forward because I was moving in second gear, and I assume it's still engaged because I can't get it to shift down to first and can't move the forward/reverse lever so it must still be engaged and working ok.

@@ToyShopRestorations i figured it out today after tearing the whole motor apart and didn't need to 😂 it was the shift mechanism. It popped off the two spring type prongs that come up on either side of the shaft closest to the outside of the case. It was so simple and I looked at that too and thought "nah, can't be that thing" and kept tearing it down until today I was trying to shift it to look at it to see what it was doing and I pushed the shift lever out by accident and when I put it back in I ended up snapping those prongs in and low and behold it shifts up and down through all the gears! Lesson learned, and I'm still inspired by your rebuild so I'm going to at least do the top end while I'm in there and already have the new parts sitting on a shelf, and will paint the frame

25:21 bruh.... Your neighbors dont want to see you do that in the middle of your yard.

😂😂😂 they’ll keep their eyes to themselves
