Ok, so some progress on my chosen bikers and lord on bike. As some of the bikes were missing the front spikes from the wheels, i replaced them with tentacles from the screamer and flamer kits. Then i used liquid green stuff to fill the cracks on the wheels and bike. Propably need to sand them a bit still. As for the lord, i added a scratchbuilt flamer to the bike and it will be the Burning Brand chaos artifact and it was made out of a demolisher squad kit lascannon and a spare flamer head i had over from my daemons army. Gotta love kitbashing

I filled some holes with green stuff on the models and now they are basically ready to be primed black and then painted as emperors children chaos space marines.
Here are a few pics. Will post the finished models when i have had time to paint them. Busy with work, so might take a while.
