I bought a used 2007 450 er I dont know anything about them. I dont know if it has a hrc kit installed on it or not. Can I look at the exhaust and tell. The guy said it was stock but Im not sure. The engine also ticks but I read that is pretty common.

How big is the head pipe? Does it bog when you punch the gas hard? Is the airbox lod off? Also, the restrictor in the rear of the pipe stock is like 3/4 of an inch, the HRC is an inch and something I believe, it is substantially larger.

Thanks for the info. The restrictor is 3/4of an inch. The header is about 1 1/2 its stock
