hey guys. i have a yamaha 2008 yz250f that i currently blew my motor. the motors shot and is not repairable. i am looking to drop a 450f motor into my 250 frame. After a little bit of researh i have discovered that the 450 motor will fit into my frame but my issue is the 250 electrical such as the c.d.i unit or magneto and other parts will not support or give the 450 motor enough power to run. I’m not a total expert on doing this and need some guidance on where to go and what i need to get to make this swap doable. if anyone has done this before and can help me it would be greatly appreciated!
