Your english is good but I bet your mom's perogies are better.
You could kinda measure the bore and stroke.
The 82 link 600 chain fits so tightly that it would be impossible to use a 78 link chain in a 600.
The 600 piston leaves about 3mm or so of bore at TDC (the piston does not go all the way to the top of the cylinder).
The cylinder should have a stamp on it showing the CC.
Take a lot of pics of your 98 cylinder and I will compare to my 97 & 98 600.
Measure the length of your cylinder and post the results.
It may take a little while to get back to you as I am at so called work right now.
