Not heard good things about the big bores on these bikes to be fair. I will do the ap mod, I did it on my drz with fcr39mx. Also need to check my throttle stop and jetting. For the short time I rode it the only real thing that stood out was that when getting on the throttle there was hesitation until reaching a certain RPM and then it takes off!

I had the same issue with my 08 WR that I got from a dealership back in Jan.
I got around the issue by installing the JD kit (comes with o-ring mod), along with the stock exhaust, both acquired on eBay via the US
The exhaust it came with was an FMF which was horribly loud so I wanted the stock exhaust.
I'm not sure what fixed it, but it still got more than enough oomph for me, it now starts much easier and the hesitation is gone.
