Are rally 180 and rally 200 cases the same? My rally 200 cases are crap, but the internals are good. I found a set of rally 180 cases and was thinking I could put my 200 internals into them. And one more thing, my rally 200 is a femsa motor. Thanks
Not the same mate, crankcase mouth smaller on the 180cc cases........
I did the swap youre describing, got the full motor built right up too the Rally 200 piston on the conrod slid the barrel down the studs, then realised the neck of the 200 barrel was a couple of mm larger diameter than 180 cases would allow.......... Dohhhh..
Its a pic I posted in the racing section a long while ago mate... I have got a 6 X 4 actual snap somewhere, I have reposted the 1991 racing thread (racing section) in the hope it shows up... cheers Col
If you want to make sure, you could measure the crankcase mouth inside diameter of the 180cc cases I can send you the measurements of Rally 200 cases and the neck of a 200cc barrel.. the barrel stud spacing is the same on both 180 & 200. hope this helps cheers Col
