Stock '87 XL600 gearing?

[skmcbride]

Trying to get an 87 XL600 back to original gearing. Anybody know OEM front and rear sprocket sizes?
Thanks, Keith.

According to the TJ Parts Express catalog I have here in front of me, the OEM gearing for an 83 - 87 XL600R is:

Front - 15 tooth
Rear - 43 tooth
