250 Motor in my RM125

[1999RM125RIDER]

Will a 250 engine and tranny from a 2000 RM250 bolt straight into my 1999 RM125? I know Suzuki did not appreciably change their bikes from 1999-2000 but I'm not sure if the engines mount exactly the same way. Is there anything else on the bike i'd have to change other than the pipe/silencer and maybe sprockets?? Also, on the 250 motor that i am looking at the flange around where the pipe attaches to the engine is broken (missing about a half inch on the bottom) ...the pipe o-ring sits inside the motor and not on this flange, so i figure it doesn't matter that its broken...comments????

I am pretty sure it wont fit. most 125s have a different frame than 250s. engine mounts are not the same. If Im wrong and it did fit you would also need to change carb-jetting and ignition.
