blaster dirtbike engine swap

[86SICKSTANG]

I bought a non running blaster for cheap a month ago and so far Ive spent $200 in parts and about 10 hours working on it. I finally pulled the jug to fix the broken intake bolt. The piston rattles a little bit in the head, rings are gone, crank has rust on it, there is metal discoloration (purple) at the bottom of the rod and left side of the crank. Im to the point that I dont want to deal with rebuilding this engine or buying another blaster engine. I want to convert a bigger dirt bike engine onto the blaster to have a quick super blaster. I have a welder and all other tools needed. Im going to try and find a cheap running bike to use for parts. Heres a couple link of bikes near me.

im going with a 1985 YZ250 motor. from all the research ive done its a pretty easy swap except for the exhaust. exhaust will be the hardest. and there will be some pretty good vibration so make sure you lock tight everything

It would be a sin not to restore that 465.

Id like to use the it 465 but it is a sweet bike and Id hate to part it out. I bet it isnt easy kickin it. Ill find something soon.
