86 250R Swing arm lenght?

[dgould]

I purchased an 1986 ATC250R and was wondering what the lenght of the stock swing arm should be. It has a West Coast Swing arm on it and measures from the center of the swing arm bolt to the center of the axle 21 1/2 inches. So what lenght of a West Coast do I have? Thanks,,,,,,

You've got a +2 over stock. 85 to 87 are 19 1/2" 88/89 are 18 1/2" center to center.
