Yes he is! In fact he is very reputable. When he asked me this question, I looked at him strange to......
But he said in Snowmobile drag racing, they actually measure the stroke and the bore, so I am running a 1000 CC, the bore and the stroke both have to be that of what is for a 1000 CC, so you cant de-stroke it etc, if you do, you are in a different class, or DQ'd. In addition, he said that I could swap my crank out for a 800 or 900 CC, they have stronger main journals. But it changes the stroke.....
And you thought your rules that you have to do is strict.......
