Cylinder ?

[bountyhunter]

Ok are all the stock Cylinders the same year to year or did they change porting some years?
I Know on SRX 440 snowmobile engines 76 & 77 were ported differant than 78 - 80
sorry just a example!

all stock blaster cylinders are identical minus a casting flaw here and there

A little further info:

The liquid cooled 32hp (84-87)DT200 cylinder is almost identical too, mostly the valved exhaust port (and the cylinder head) is different.

The aftermarket cylinders are very different. Extra ports and additional transfer and exhaust duration.
I do not know about the cheap cylinders offered on Ebay at the moment.
