I will mount a CRF70 swingarm on a CRF 50.

Which chain length do I need with the stock gearing?

we only sell 130 link ,,,,you can just cut it

Ok.

Does anyone know about how many links I should cut it down to get the right length?

Move adjusters to full-forward, wrap chain in place, with overlap at rear of back sprocket, pulling tight. Hold thumb on plate to grind.





Or, look up a 70 length, find the difference in stock sprocket sizes, and math it out.
