Suzuki 2 Strokes

A friend needs the measurement of GT550 cylinder spacing , he says the measurement between spark plugs would work .. thanx

I will measure mine when I get home from work tonight if no one else responds before then.

FYI, the spark plugs are NOT centered in the cylinder domes & they are all at various angles, making it kinda hard to get a good measurement.

I measured on the underside of an old head between similar points on the cylinder domes
(i.e. Right edge of the Right Dome to the Right edge of the Center Dome). ABOUT 4-1/2".
I don't know how accurate you need to be, but the best I could do is:

Right cylinder to Center cylinder = 4.53125" (4-17/32")
Center cylinder to Left cylinder = 4.484375" (4-31/64")

See if this is close to what others might have for you.

Thank you for your help

Measured one of my heads as well and came up with the same 4.5 inches, center to center, on all three. Just curious, why does he need this measurement??
Cliff.

Thanks so much for the input but alas he didnt tell me what the need for the measurement was for

The way the pictures were taken makes it look off, but I also got 4.5" from my heads as well.

Thanx all for your help with the measurement , he said his interest was in attempting to fit other cylinders to the 550 cases .

As in RD 350/400 top ends per chance?

OMG. Let me see. CPI Cheetah makes about 130HP or more so a triple would make around 200HP and the GT bottom end would just twist itself into a pretzel.

I wonder if I could get away with one of those in the Phat Trakka without anyone noticing that it's not stock?

More to the point, how long before someone builds one of those for SE in a custom chassis and starts to set a new all time record for a triple two stroke.

I think you guys are on to something. That would be one insane triple.
