now mine has a 27mm intake port , ?? is this a swap head from the 79 ?

Not sure about the port size difference between the early head and the later type. Do you have the carbs that match the boots on the head? If the boots match the CV carbs you have the later head, and visa versa; VM carbs & boots mean you have an early head.

Some of the early VM heads don't have the extra bolt in the front center of the engine either. If your head doesn't that's an immediate tell it's an early head.

The 1000G was not made in 79, started in 80

The 79 850 had 26mm carbs. You sure it's a 1000g motor?

The 1000G was not made in 79, started in 80.

Yes and no. It started with the 1980 model year, but the early ones were asssembled in late 1979.

Don't know exactly when they started assembly, but August or September was not out of the question.

Yes,but he's talking about a 1000G engine with 27 mm intakes

Suzuki didn't make such a motor (at least in the US)

That's why I'm asking him to look at the front of the motor and confirm it's a 1000
