Help identifying head

Recommended Posts

Hi guys I’m having a bit of trouble with an engine that I was given for my project. The barrel says 748cc which makes it an 88/89 dot head but the clutch cover I think is off a 90/91 but the head is missing the casting dots so I’m guessing that the head has been swapped but I have no idea off of what.

I have no idea lol i did also notice where the inlet rubbers bolt on the hole of the rubber don’t line up perfectly with the inlet holes of the head and came with 36mm carbs which I have just fully rebuilt and stage 3 jetted to now find I don’t have a dot head

If you took the head off you could measure the valves. 750 dot head has the same size valves as the 1100 ones long stroke 750 have smaller valves. Only other way is the carb rubbers as you say they dont match, but can be trimmed to sort out the steps. All the carb rubbers match the head they were designed for.
