What model and engine size 107 - 117 etc? Is this a good belt drive?

[Sevrokev]

I just bought an 03 big dog, I am not sure the correct model name or engine size.

You can also call s&s and give them your engine numbers and they can tell you exactly what's in it and what it is.

It's the same. Yours is the 4,787th 4" bore crankcase made in 2003.

Thank you. I had already watched this video, but it didn't tell me what ci it was. The guy that sold it to me said it was a 117. Thanks to people like yourself, I now know that it is actually a 107.

Anyone that knows big dogs, knows the '03s have a 107. If we knew nothing about the motor, there is a way to figure it out. From the engine code, we know that it is a 4" bore. To find the stroke, you could remove the flywheel inspection plug from the crankcase and rotate the motor until you see the number in the second part of the flywheel code. It should be a "5". This is the code for a 4.25" stroke. 4" bore x 4.25" stroke = 107ci.
