31L is listed as 1983/4 RD250 which would make it a version of a 29L YPVS 250
If number is genuine untampered it has came in from another country but have never heard of 31L other than superceded tail lights and looms starting 31L so must have been used somewhere

I guess it will be the same bottom end as 350 just like the rest of the lc's

The cranks are the same,if the wiring fits yours then there's no probs,I'm not totally sure the stators are different as mine went back in the same bike,Matt
