I'm not a fan of Da Jumping meganobz, I prefer putting them into vehicles. I think 3 trukks are not enough though,
IMHO the 8th edition bullyboyz could work better with five min units of meganobz in five trukks.
In my games bikes worked better in min units as well.
KMKs are ok, but they don't have a long range, split them into two units of two and a solo
KMK or a unit of two and a unit of three.
You could take a regular warboss to save some points, now the biker one is only 99 points. I'd also recommend a killsaw for the big mek or the killchoppa. The painboy and the banner seem appropriate in a list like this, I wouldn't drop them.
Overall I love the list and I'd really like to try something similar
