So my title says 1973 - the manufacture plate says 8/72 (VIN is GT750-25247). Engine serial number is 25639. Color is the red burgundy.
I You Tubed "1972 GT750" the other night and watched a dozen or so videos of 72's and all but one video shows a 2-bolt plate design mounted on the head intake port of each cylinder. Only one video had the nozzles cast with the heads.
Mine does not have the 2-bolt plates but has a nozzle as part of the head casting to accept a carburetor-to-head boot utilizing two "hose" clamps to affix the carburetor to the head.
Does anyone know about the dating of the nozzle design change ? Was it a mid year change, or a Asian/European/US location issue ?
My parts engine is 200 miles away and has the two bolt design but I think the engine serial number is a later model (but not sure).
Plan on seeing what it'll take to correct the title sometime this year

Re: Head inlet nozzle question on a 72J
Found the answer here ... https://www.oldjapanesebikes.com/GT750_ ... de/page-61
"The carburetor mount was bolted to the engine during the early production and then switched to a spigot mount as was used on the 1973 models, starting at frame number 21134. The photo to the right is of the earlier bolted flange mount."

Re: Head inlet nozzle question on a 72J
Hi Steve 72J.
Does your tank etc look anything like this enclosed photo.
Ok this is an 73 USA ONLY colour, but I think some found their way to West Germany.
By the way the double disc was also listed as an optional extra on the J models, also find confusing is your remarks about the barrels carb mounts, having viewed two internet sites listed, makes me think this is either an extraordinary early K model or someone has changed the barrels over for a K set, for whatever reason. Only your piccies will help to confirm one way or the other.

Re: Head inlet nozzle question on a 72J
My bike was a late 71J and had the cast intake stubbs with the rubber adapters on the barrels. I always thought it was only the L, M, A, B bikes that had the bolt on stubbs?
They're rubbish them Jap bikes lad they won't last five minutes! you want to get yourself a nice Royal Enfield!

Your bike is right same as my bike.

The later JAnd K Had slip on flange
