A few notes here.
1) We rarely give Enhancement Bonus to loot drop weapons. By far and large we prefer to go with attack bonuses instead. I do not feel you need to add any here anyway. You already give it damage bonuses and that suffices. The enhancement bonuses are very easily covered through Greater Magic Weapon buffs or easily available magical varnishes that will make them +3. And that leads to my next point.
2) Taking out the EB on the suggestion would reduce the cost value and therefore allow you to tone down the penalties on the item. We try to keep away from items with prohibitive penalties. Items with a -10 to a skill are less likely to be considered.
3) You ought to pick more meaningful penalties too. An influence penalty on a weapon is pointless. Influence is never a skill used in combat making your penalty toothless. I think a -1 on Universal Saving Throws would be better for balance. You want penalties that will apply in situations where the kama is actually wielded and used. That means you need penalties impacting battles.
4) The cost does not refer to a suggested market value, but the actual GP value when you make the item in the toolset. Please be sure to follow the instructions in the Item Request thread. Make your item in the toolset before suggesting it. This will allw you to see what is possible and what is not. It is the cost value returned by the system that helps us gauge it's drop probability. Be sure to keep the item below 8k value else it will likely never drop.
