If you're gonna use a rope seal like you'd use on a car or truck tire said:
The tar strips do not work well in MC tires- trust me. They'll hold long enough to limp home, assuming you drive easy and no high speeds. MC tires flex in a way car tires really don't, and the cords/belting in a MC tire is much much thinner than in a car, so there's less for the tar rope to "grip". But while they can be considered a permanent fix for a car tire, they are an emergency, get-you-off the shoulder fix only for bikes. The mushroom style plugs (Stop n Go) do work better, but still to me are an emergency fix only. I would not ride aggressively or assume it is permanently fixed. Don't combine a sealant (Slime) with the external plugs- the lubricant properties of slime will let the plug pop out in no time.
If you ask the tire companies, there is NO "safe" way to repair a MC tire and replacement is the only option. Then again, if you ask insurance companies, there is no such thing as a "safe" motorcycle, and you should probably just take a car everywhere. However, if I get a nail on a nearly-new tire, I will generally dismount it and use an internal patch. I have had 100% success with these. No leaks for the life of the tire. Including on sportbike tires that were ridden very aggressively on. If the tire is almost worn out, I'll probably just suck it up and replace it. Not worth the hassle of a dismount/remount/rebalance for a tire that's only got a few weeks left on it.
Was there an object in that little tear? I have found nails/staples/ect that went in at a very sharp angle, so they didn't actually puncture the tire and just tore the tread a little. If it's not losing air (put a dab of spit on it and look for bubbles), I wouldn't worry about it.
