Some stealerships are keeping the PU kit to sell them later. An 09+ should come with the PU plug as
OEM equipment. BTW, you can make your own PU "jumper/plug" and buy an O2 bung plug very easily. A PU jumper is just a 2K resistor across the O2 sensor heater circuit. You can find alot of info about that on Cafehusky. It cost me a total of ~$10.
I have an '08 SMR and it needs ibeat EFI reflash/tuning. The '08 runs
VERY lean and will stall on occasion. From my research, they all run MUCH better with an aftermarket ECU module. As for breaking in, it's the same as any other bike. Just make sure your check all the engine case bolt torque settings. Most '08s are leaking oil from the case due to improper torque (the
manual has the torque settings). Also, the stock exhaust is heavy as hell. If you are lucky enough, you can find a used '08 TXC exhaust and use it. The TXC exhaust is a an Arrow without the catalytic converter. Otherwise, you will have to find a slip on. Plus, I don't think a '09 single will fit an '08 (somebody correct me on that if I'm wrong). I shelled out $375 for an Arrow.
One piece of advice, if you are planning to do any dirt/trail riding, can I suggest you get a TE so you can go SM much easier than you can go the other way around. A TE is essentially the same bike with a kick start, dirt wheels, and a 240mm? front rotor. That way you have two bikes in one for the price of a 17" front wheel and a caliper relocator from someone like Warp9. Just wished I had followed that advice.
Let me know if you have some other questions. It's just too bad you aren't near the DFW, TX area, since I am selling my '08. The bike is great, but I want to do some trail/dirt riding and want a true enduro. Hope that helps.
