I have a honda 400ex that is all set up for mx. I had a 440 motor in it but was wanting to possibly build a hybrid with that frame using a CRF450r motor.

I was wondering if anyone could guide me a little bit on how to find a mount kit for the motor and radiator and anything else that is different.

I would really appreciate the help or if anyone is selling the parts please let me know.

Pictures of my quad as it sits now.

You would most likely be on your own as far as fab work.
Do a search, there's tons of crf threads in here to look at.
Or sell your 440 and buy this guy's: http://www.exriders.com/vbb/showthread.php?s=&threadid=448591&highlight=crf450

It will probably be cheaper than building a nice one. Especially if its still on ebay
