GT750 Port timing heights
Hi all! i was wondering, was 1977 a stand alone year for port timing height? or were 75, 76 and 77 all the same. im asking because i have a 1977 cylinder and all i can find to re sleeve it is a sleeve for a 1976. i know the port timing changed in 1975 i was wondering if it changed again or 75 was the only change?

J, K were same, L, M were same and A, B were same AFAIK.
Think of how stupid the average person is, then realise that half of them are more stupid than that.

Not quite right,
The J.K.L.were the same.Porting was changed in 75 and continued with the same through 76.77.

Correct Old Racer.
JAycee, if you don't mind sharing, who has liners in stock or can supply them? LA Sleeve used to list them IIRC.
