trx 450 motor in a hybrid 250r frame

[jeremy444]

Has anyone tried this? I have been looking around but have yet to see anything. I found a hybrid but it is set up for a 426.

I am building one right now. I have a 03 LSR yz426 chassis I am going to put an 07 trx450r motor in.

how is the swing arm and motor matching up?

Have not got the engine from my brother yet. I have the crf no link swingarm. There is pictures of the rolling chassis on trx250r.org under the hybrid section(My LSR hybrid build). It would be done by now but I pulled a muscle in my shoulder racing. I was off work for two months and had to put tires on my truck. So that took all my money to buy the 07 450 from my brother.Now iI am trying to save up some more money.
