It took me 6 month's from start 2 finish, a couple night's a week, sometimes not working on it for a couple week's. Not just on the fab work, we had to replace every bushing/berring and completly rebuild the entire engine.
The engine has a FST 500cc stroker crank and a 1mm over Honda piston, whatever that comes out to. I like to say it's a 510 cuz it sound's cool.
I started this project with just making a waterproof IRS Foreman in mind butt it turned into the Sledgehammer, it took on a life of it's own. I comited myself to it when I started and it took 3 month's longer than I expected.
I have absolutly no plans to build another one and would not do it for $$$. I don't have time and I realy don't like doing stuff after work, I get enuf of it at work and work is not fun. I'm hoping to not be in this buisnes at all in less than 6 months. I will still do stuff for myself and my family but that's it.
