I don't think it matters too much but I was just wondering about my 1980 CM400E. According to the on line PDF Manual there's a Type 1 and a Type 11. Not much difference from what I can see other than some of the Specs. The Manual says a Type 1 weighs 351 pounds and it has no Tach.......just Idiot Lights. Type 11 weight 370 pounds and it has a Tachometer. Well......my Title says mine weighs 370 pounds with no Tach. Does it make that much of a difference ?
