Was there any pitting on the fork stanchions? It there was it could have damaged the new seal. Did you fill the oil to the correct level? Did you use Yamaha seals or aftermarket ones? Aftermarket seals can be a bit hit and miss and not seal properly.
It would be unusual to happen on new seals but sometimes a seal leaks because a bit of dirt gets trapped between the seal and the stanchion. I used a sheet of printer paper rolled tight around the stanchion and then pushed the paper past the seal to remove some dirt and it stopped the leak. That was on an old seal but it might be worth a try. The alternative is buy another set of seals and do the job again. I'd recommend Yamaha seals.
