chain links?

[200x newby]

Ok I need a rough guesstament. I have a 1986 310r with a +9" extended swingarm a 44 tooth rear sprocket and a 15 tooth front sprocket. Will 120 links be enough or will I need more? Approxemently how many will I need? If someone will count there links on there +8 to +12 and get me a count I can add or subtract from there. I need to know within the next 2hours if someone could help me out.
Thanks

whats the stock gearing and chain on a 250r? if the stock chain would fit about right with your gearing, figure out how many links are in 18", and then add that to the stock chain plus a few to make sure you goto enough.

stock gearing is 13 39 but i have no clue on the stock chain MAYBE... 96?
