Crank Welding?


Recommended Posts

I have a few a questions, and the only way to learn is to ask.

What exactly IS your crank, and what does welding it do?

And what HP and top speed do you think Im looking at on my bike with the mods listed below? (It also has some crazy carb <not stock>) Thanks for any help, its cool to have a place to ask questions.

How Stuff Works

 

good stuff about Cranks, and how they transfer energy from the pistons, into rotational energy.

What do you mean it has some crazy carb?

Do you only have 1? Trinity setup?

 

What is your rear tyre size and what size sprockets are you using, your top speed is affected by these

Holy shit, I was JUST at this exact spot online the other day. I know what a CRANKSHAFT is, I didnt know what a crank is, and apparently Im an idiot cause theyre the SAME thing. Ok, so what does getting it welded do? And no, I have 2 carbs, I just dont remember the name so I said crazy. Let me go into my garage and check the name, BRB. Whatever, I dont know, maybe they ARE stock after all.

getting the crank welded is just reenforcing the mating surfaces of the Crankshaft. Allowing you to run higher compression for more power.

I'll elaborate, mostly because its late, and I'm bored.

The stock banshee crank isn't forged like a crank in a dragster engine. All out of one piece of steel, and the grain follows along the lines and bends.

The stock banshee crank is pressed together, something like 7 individual pieces all pressed together to make up the crank. Now, if you get enough HP out of your engine, and your clutch can back it up, there is so much pressure between the clutch side of the crank, and the connecting rod journals trying to turn it, that one side will actually slip due to its being pressed together. I have a twisted crank at my shop I can take a picture of to put up here tomorrow if you would like.

When you weld your crank, you are welding the individual pieces together to make them all one piece. It isn't a HUGE weld. Usually its a smaller TIG weld on a section of the piece being welded. Something that can be ground off later should the need arise for some crank work to be done.
