Break In?

I called ToyTech (which is further then my other husky dealer, but I'm going to try him out first because of his reputation here) and he said i should have my initial service for my sm510r around 600 miles, I bought it with 700 something. So I am planning on taking it over to get that done within a week or two, but do you guys think its ok to ride it still? I mean im not beating the piss out of it, just cruising around. What milage should I definitely stay under? Thanks!

Hopefully the previous owner changed the oil at less than 100 mi. Should have had a couple more before 600. At 700 you should be good to go to ride it like you stole it. I'm sure they'll check the valves too so ask them if they needed adjustment just for reference.

Its bone stock, but I think it had the power up kit installed at the dealer when the original owner bought it?

Oil changes are the thing to be concerned with. It should have had a couple done by now. Break in is just about done as far as the engine go's. Just change oil and get on her!
