Just split the crankcases on my 1600CT, found both centre main saddles (centre main bearing) are cracked right the way through. Guessing this means the cases are scrap?
Was planning to build a 1776 (got barrels & pistons) but going to have to rethink now. Anybody reckon it would be worth getting new/good 2nd hand cases or go back to buying 2nd hand 2.0 CU and rebuild that.
Cheers
Pretty common on the CT. Another of its little quirks. I'm sure someone on here will have a case that you can get machined. You'll need to check the crank for straightness.
