Ty175 Barrel Questions

Hey all,

Just started a long overdue restore on my TY175 in Australia. The engine will be rebored with a Wossner piston.

Is there any differences between the model 525 barrel and the 1N4 barrel? I have a spare 1N4 barrel that will take a 1st oversize rebore better than the 525.

thanks for any help!

    I know the barrels are interchangeable but was wondering if anyone knew if the port timing or sizes were different.
