All the Ways I BROKE the Engine - Yamaha Virago Build Ep12

Knowing that the bike runs isn't enough, we need to pull the top end and inspect. Turns out ~30k miles are pretty rough on these old v-twins as the cams are toasted. After breaking one of the pistons, gouging the cylinder head mating surface, and realizing I need new/rebuilt cams, we better settle in for a couple weeks of waiting for parts.

You're the guy who always knows the guy to rehab old parts!

I recall during the 80s a problem with the starter motor sorted by using or adapting one from an xs850.

I wouldn't turn that the starter gear around, I read that'll do more damage than good. I'm not 100% but there's tons of forums that say don't do it. I also read that removing the spring in the starter gear is recommended by yamaha and they actually provide replacement parts. But these are just based on research I was doing so if I'm wrong and there's a better fix then I'm all ears. I know classified moto talks about it vaguely but they eliminated the "box of bolts" sounds by removing the spring and upgrading the part.

Thanks for the tips! It's hard to keep all the info about the starter system straight, because everybody seems to talk about how much it sucks and offer different advice. Shortly after posting this video I decided, as you suggested, not to flip the gear around. It would be foolish to spend this much money on a project and then skimp out on something so important. I'll do a bit more research and either way end up going with new parts. Thanks again!

May I ask how you broke that piston skirt? I'm working on a 920 engine and I'm hoping not to do the same thing while turning the engine over by hand. Great video! Can't wait for the next one 🔥

With the cylinders off, the piston can lower into the crankcase an inch or two. While I was rotating the engine by hand with a wrench, I should have held the piston straight as it dropped into the crankcase. Instead, it was a bit crooked and the edge of the skirt rested on the crankcase. I felt it 'stop' but thought it was just a kink in a cam chain or something so I gave it a little 'oomph'......then it just sheared right off. I've made more expensive mistakes, but it still stinks!

@@two-cargarage I appreciate the explanation, Thank you!

How do you know where to source the parts from?

@two-cargarage Год назад

It's tough sometimes with these old bikes! The cylinder and piston I have to get used off of eBay, which is usually where I find used parts. The cam work, however, will be shipped out to a company in California that does it
