Please please pleaseeeee make more😅 im sotting here in my garage putting a new Rocker cover gasket on my 06 zx10 and I needed a break so I watched the vid and damn man gave me some motivation to keep going on my 10🤙🤙🤙 love the vids I've been watching since the bmw plz keep them coming
Awesome vid. You made it look so easy and straightforward; don't recall any of my engineering classes were that straightforward... Anyway, ride safe, god bless u.
Gentle 'tapping' with a very-small engineers-hammer , gives more-even-torques and helps-release any binding-tensions ie ; on big-end-caps, nuts etc , then re-torque , obviously taking-care where you-tap, not distorting the 'flats' on nuts etc . The same-technique can be used when welding 'Cast' , stops stress-fractures by relieving tensions in the metal . Dave NZ
Looks real nice! I have never had a leak using Yamabond 4. It's meant for gasketless metal surfaces and is great stuff! I have always wanted to try it on aircraft engine cases and oilpumps but have not yet. We have to use inferior FAA approved substances that many times do not work!
Motorcycle engines are put under stress quite often but never seem to leak unless impacted. Downdog, when you apply Yamabond, do you apply it in a bead (which will flatten out once the case halfs are bolted together) or do you apply in a thin coat?
@@blipco5 Yamabond 4 is kind of runny so a bead is not really possible. It doesn't take much. It also should be said it doesn't have a long shelf life once opened. I usually buy a new tube when assembling a bottom end. A thin coat is all that it takes on nice surfaces.
@@upsidedowndog1256 Ok thank you. My favorite of all time for side covers is Hylomar HPF made by Permatex. My twenty year old tube with a few drops left in it is still good like the day I bought it, while the new Hylomar skins over quickly and the opened tube goes bad in a year or so.
@@blipco5 I have used lots of Hylomar over the years. We used it on aircraft engine case halves for years. It was invented by Rolls Royce for imperfect machined surfaces on aircraft engines and can actually be used where oil never quits running out like a prop governor. DO NOT USE IT NEAR ANTIFREEZE!! I like that stuff bt Yamabond 4 is next level better in my experience (33 years aircraft, 42 auto and motorcycle).
I respect the skill and dedication. I have never heard of a split cam before. I would think a regular cam would be better to prevent gear lash because it is one moving part instead of being split. Very interesting.
For about a year or two Honda had a split journal crank in the Shadow, I think it made more hp, and slightly better fuel economy. Would like to find one. They stopped making them because they didn't sound "like a harley".
I plan on doing a virago 81-83, it's a bitch to find a donor bike near me though. The only 3 I've found within driving distance are either too rusted out or too perfect. The only reason i want a Virago is for that monoshock. If i could just find one with a decent frame I'd be happy, I'd even do an engine swap and I had planned to do a custom carbon fiber tank and levers/pegs. If I did the engine swap I'd definitely look at doing a forged carbon swing arm as well to reduce sprung weight and look good. Your build is coming along dope though.
Something that might be helpful when deciding to reuse or not if anything has a torque to a number then angle that's is torque to yeald and should not be reused. In theory anything else that is in good condition can be used agian. Most race teams will only use a bolt 2 times. Any stud, and nut can be used agian and agian. By the way. love watching your builds. because of you I'm going to be going pretty deep in to a cheap bike I just got. I have a nicer bike I do matince on and mild modifications but I haven't done an engine yet.
Good video with great details, but why are you opening up the engine? Is something wrong from the inside? I am also working on my '82 XV750 but so far I don't see any reason to open it up.
I got two questions. One being can they vapor blast an engine without a complete teardown? 2 the smaller wire brush where did you get? Is it something you made or something that can be bought?
If you get the engine parts blasted they have to be completely stripped because the "media" or grit material can get embedded in places and ruin the engine when you run it. The wire brush is available here
Not all V-twins have a single shared crank pin like yours. That design limits horse power which explains why Harley engines have lower specific output compared to, say a Shadow 1100. Several Japanese V-twins have seperate crank pins offset to make if fire closer to 180 degrees.
