Exhaust difference 71 and 74?
« on: March 03, 2008, 04:01:06 AM »
Will the stock exhaust system off a 1971 CB750 fit on a 1974 CB750?
If not, what is the reason?
Thanks for any info,

Yes it will fit. I have a 1970 exhaust on my 1974 CB750. 

Check and see if it says HM300 on the pipes or HM341. HM341 was used on 1972-1976 models and HM300 1970/1971. 1969 had unstamped pipes - rare.

cheers
