Hey guys, Merry Christmas! This is the 1998 YZ125 engine I got in bins (literally.) I decided to restore it and turn it into a mild 144 big bore and it became the heart of the Grape Ape build! What bike should I build next? For people using this as a tutorial, all chapters and tools are listed in the description 🤘

You can do it. Get a great manual like Clymers. Go step by step! Double check yourself. Mainly u need some good basic tools & a TORQUE WRENCH 🔧. Learn how to use one! Use Maxima oils /chemicals or Yamalube ONLY.
@MichaelSabo2 жыл бұрын
Hey Troy, I'm glad you like my videos; Like David said, you can do it yourself too! There's no better way to learn that to get your hands on an engine and learn from experience. You can grab a lawn mower or weed wacker from the trash and pull it apart then throw it away if you mess it up. Yes... I used to do stuff like that as a kid 😂

I ended up putting small washers that were the same size as the power valve shaft to hold my springs in place on my stock bore Athena kit for my yz125. Works as it should. Really wish I didn’t have to do that though since you pay a premium price for that kit. That’s honestly my only complaint about it though. Other than that it runs like a champ.
@MichaelSabo2 жыл бұрын
I think I see what you're saying with the washers. I agree, it's a shame because it's such a small inexpensive (I would think) for them to upgrade and make right.
@keithpeterson34472 жыл бұрын
Put the crank in the right side crankcase first & pull it tight. The gear/spacer will want to pull the crank that way. Lay the right case on a flat surface facing up & drop in the transmission. Drop the left side case down on it & pull until the surfaces touch with a very minor squeeze. Drop in the case bolts & tighten it up. This should be super free spinning bottom with everything "set" as far as bearings on the crank. Never hit the crank. The idea of "setting" the bearings would be best done with a thick brass punch & a steel hammer. Then hit the cases near the main bearing bosses with the hammer & punch. The high pitch "ring" or "shockwave" will let any races that are "bound" to "jump" into place. I use the hot cold thi g but that process is hit & miss for people until they know how to do it consistently successful. Learning how to heat a bearing in the case without burning (overheating) the bearings or seals ect. The other thing that is a huge "no non" is the impact on the shift drum bolt. You HAVE to use a hand tool for that & make sure to rotate the drum to the "stops" before tightening. If the power tool hammer on it & the gears don't happen to want to let the drum "freely" roll to the stops, one of the forks can get bent as the drum puts a sideload on the fork & the gear is bound. Yamabond 4 is the absolute best for the cases. Thers vintage sleds tgat are 40+ years old & have never had the cases opened & they still run like new. The stuff never broke down even after 40+ years. 👍 Don't "knife edge" anything in the intake or transfer area. A rounded "bull nose" edge is best for anything facing the airflow. You can "knife edge" any bridge in the exhaust if you want. I still go with a "slight bull nose" in the exhaust because there is movement both ways in exhaust port & the first part of the pipe. Anyway, not meant to offend. All things that a guy like you can see would be of benefit. Rad bike. I have a 2001 sitting that I had been thinking of pulling out & doing a build. I can do a pretty rad build for a lot less than buying a new bike. Seeing your vid has me motivated to start pulling ot out for a winter project (I live in Wisconsin).

Hey mike great Job on videos. Finally after 30+ years. Someone who tells the truth about the steps they use to build. Even the little common sense things that would have instruction police loosing their minds. Because just sometimes that $800 pencil sharpener just isn’t necessary. Lol. Great work. Oh and yes normally they always start torquing from inside working opposing sides working your way out especially with gaskets. So that the pressure works the gasket out pushing any buckles out to the edges. You were already on the right track though. Love my Yamaha. You are smart enough that you should do a 660 raptor speedwino fuel injection conversion. Or maybe a micro squirt? People have changed a lot of machines. But I can’t find a single 660 raptor anywhere. I think everyone is intimidated by the twin carbs. But I have a feeling you could figure it out. I have about 3 fb groups that have all had questions about aftermarket fi. On our machine’s. I’ve been doing research. But quickly found myself financially not able to experiment. Just a thought. Thank you

Hi dont know if anyone caught it but before installing the crank gear on the clutch side you have to screw in the crank seal retainer he left it off in the video and I saw there was a missing screw hole and I had an extra retainer left over so make sure yall put that on before you bolt your clutch pack on, waste your time and have to take it all off and redo it again just to screw on the seal retainer
