Swapping a cr125 into a trx 70

[oldo]

So I'm wanting to swap a cr125 or 85 into my trx 70. I'm thinking the 125 because there is an additional engine mount on the cylinder head to secure the engine better? And more power of course.

I know it's a bucket load of work but keen to build one.

One of my questions, with radiators: cr125's run two, would running a single banshee sized radiator do the job?

If I run an 85 I'll just mount the single one it has from factory

 

Any insight would be great thanks. I'm in Aus by the way. Here's a pic of the trx frame ??

 

[S.O.A.N.Z]

will the 125 fit in the frame - no clearance issues ?

are you handy with a welder ?

Yeah pretty handy with a welder/ know multiple fabricators that can help me out if need be

By gauging the engine size of my yz125 it should fit. But I will make some templates to double check
