    What a wealth of information! Learned quite a bit. If I had to guess more damage was caused by ignorance than anything else. Before the internet, owners (mostly young people) had no readily available sources to research what to do and how to do it. Thanks to Dale, we do now!

      Thanks Jim, I learned a lot also, everyday, its what keeps our minds sharp as we age. Im not sure if its ignorance or they simply dont know better. Yes info is out there for sure, it is still up to each person to decide if the info is bullshit or good quality. I remember as a young man, pouring over magazine articles to find the info I was looking for. Remember before the internet you had to know a mechanic or a machinist to ask questions, but they may not answer because they needed to protect their livelyhood. They would just say....leave it I will fix it. But you cant watch. Hey thanks for hanging out with me in the shop.

    Great video Dale!
    That drives me crazy! I also often find welded shifters, Kickstarters and I had a crank/lower end rebuild done by a local shop (which is no longer in business), I got my lower end back and noticed deep vice jaw marks all over the counterweights. He said that’s normal with a crank rebuild. Got home to do the top end and the piston was sticking out of the cylinder at TDC. He installed the wrong rod. Wouldn’t return my calls. Lol. It boggles my mind why people can’t do things the right way.

      Right on Noah...just recently had a welded on shifter, boy what a mess. Wow what a bummer about the crankshaft rebuild. The story you shared is very typical, this had a lot to do with me picking up the equipment to do my own machining, this way if its messed up, I only have me to blame. (I do mess things up too) I just consider it part of learning. But when you pay someone to work on your stuff, you expect the learning curve to be over. Thanks for hanging out in the shop with me.

    Indicate the small end of the taper too to verify its square in the 4-jaw. Nice job

      Hi thanks for hanging out in the shop with me, you bet, if you dont it will never be straight, that is also when you find out that the snout is bent from being beat on. Not this one though it does appear to be a good canidate for repair. Keep in mind though, I am not a machinist...learning as I go, the job is not finished yet, so we will see the results soon. I will show indicating that in the next part, I appreciate you pointing that out. Thanks for the support and following the channel.

    Just my kind of thing Dale, it's shaping up to be a nice repair. It bothers me that people would rather destroy hundreds of pounds worth of crankshaft than shell out a few pounds for the correct tool. Those of us that tinker with old bikes just have to accept that they have probably passed through unskilled hands in their time.
    Great machining shots, I very much enjoyed the video. May I ask what makes of lathe you have in your shop Dale?
    Best wishes, Dean.

      Thanks Dean, yes folks just dont pay attention to what they are doing, and to what, the results may be.
      My bigger lathe is a Jet 1340, 13 inch swing, 40 inch bed. The smaller one is a Atlas 618, 6 inch swing, 18 inch bed.
      Thanks for hanging out with me Dean.

    What I've seen on the Yamahas is that someone will stick the fingers of a puller through the holes in the flywheel and as they crank it out they totally tear up the source and lighting coils.

    • @montana2strokeracer
      @montana2strokeracer  2 ปีที่แล้ว

      Hi Jack, yes I have seen this also, folks really must look before the do something like this, I saw a TS250 Suzuki that uses 3 bolts screwed into the flywheel attached to a puller to remove the flywheel, Well....someone screwed the bolts into the flywheel too far and then turned the flywheel and it just ripped the lighting and cdi coils. But I guess my pet peeve is the hitting of crankshafts with hammers....

    The pinion flange in my car has a small groove in it that's causing a leak. I knew there was an easy fix for it. Well, "easy".

    • @montana2strokeracer
      @montana2strokeracer  2 ปีที่แล้ว +1

      Awe yes, I think in your case I would use a speedi sleeve. I have used several on pinion flanges and driveshaft yokes. Lots cheaper and no machine work. Yes "easy" is a relative term in this case. Ha, ha, ha. Hey thanks for hanging out in the shop with me.
