Engine Question???

Does any one know if a 900 engine will fit in a 650 or 750 frame?

 

There were some factory 750's with 900 frames.

The reverse may work as well, at least the mounting points will line up.

 

kool thanks

 

maxims and seca were allk derived from the 650 maxim ok well all 650 700 750 900 secas in the early 80s were the same outside diminsions they were like the medium blocks small blocks were like 550s and 600s then 650 700 750 900 the 850 was a triple and a nightmare. i have a 900 hundred block sitting in my garage that was in my 83 maxim 650 that looks like a 650 turbo seca but it does fit exactly the same same everything except bore and stroke. i do need a piston for a 853cc 900 seca if anyone knows where to find one. just standard size 67mm.
