Hello everyone my name is Ryan and i am new to the forum. I have a question that I’m hoping one of you will be able to help me with. i have a 2005 yamaha kodiak 450 that needs a engine replacement and i found someone on craigslist that is selling the engine from a 2004 yamaha kodiak 450. I looked up the OEM part numbers for the crankcase and the head gaskets and everything seems to match up besides for the drive shaft assembly is slightly different the 2004 has a solid rear axle and 2005 has irs. i might have to replace the you joint or something but i think it should work. Do any of you have any experience with this or have an insight that might help me figure out if this is possible. Thanks for your time.
