Thanks for all the help and wisdom guys.
I'll try the practical stuff first but will end up fabing up case splitter eventually because my 2stroke is next.
Id have you buy a splitter if youre going that route. You want to push on things in a straight line. I just split the cases on a 1986 ATC 250R engine. It put up a significant argument but still only needed 10 minutes to get it done.
The Tusk case separator is a piece of shit. There are several copies of the K&L separator (the one I have) that look identical for a lot less money. Amazon and a couple other places I saw online were offering it for roughly 40% of what the K&L tool costs. A steering wheel or pully puller really doesnt work. A two leg puller works with a lot of the newer two strokes. You can find those at most Auto parts stores for 15 bucks. At that point all you need is a length of 6mmx1.00 threaded rod for the pulling studs.
