New 400ex owner!!!

Just rescued an 03 400ex from a guy who had it sitting in his garage for over a year. I already started breaking it down for rebuild and powder coating. I'm thinking about getting the 460 stroker big bore kit for it but don't know much about it and I was wondering if someone who knows a bit more about that kit could tell me if it's even worth it...

Hey someone from Mass,,,I am in Seekonk,,,

In regards to the kit, I would be concerned about heat, need extra cooling...?

I actually never heard of seekonk a d I've lived here for a little over 20 years. Where abouts is that located?

Well the manufacturer makes there own custom 89mm sleeve, so besides the the piston the only other thing that's different is the crank, but I am not sure about the heat issue. I'll have to call the manufacturer and ask. I've YouTubed the 460 kit and only found 2 videos and I didn't notice that they had some type of diffrent cooling medium.

By the way, do you know of any places to ride in Mass and not get chased out lol...?

that's a little ways from me but not bad. My cousin also has a 400ex and our buddy has the kfx700 but as it is right now we are looking for a consistent place we could ride locally on the weekends. If you could name a couple websites that would be swell...
