sorry about the grammer i cant read my kids text message so i understand.I for one believe the 07 had the best mapping in the ecu but i never rode a or but did get the reflash.have you ever taken a bicycle wheel and spun it and held it in your hands while spinning?Its really hard to turn it while spinning I beieve the the 1000 crank is the same way it enershia i think thats how its spelled just my opinion I took my 1000 and put on a bdx air box 10lbs lighter speedwerx y,pipe,and can they say around 22lbs heck i even had the cylinders ported what that a few ounces lol boss seat 2 wheel kit and when riding it it was still nose heavy comapred to a friends 09 m8.When that big crank gets moving it really is alot of force to deal with while boondocking but im only a 170lbs jmho if it was me id wait for the market to drop out of the 10-11 m8 same horse power way lighter if your under 225lbs id buy a m8 if not buy a 1000 the one in that pic i sold for 5500 without the seat or pipe or cylinders.If you get one have brent linderman port them pipe it then try to hang on to it you will smoke a pump gas on short pulls.JMHO
