I got the green light from my wife to snowcheck an 07'But after some serious thought I am trying to decide if I should just keep the '05 800 and put a RK Tech 827 kit on it for $2000 or spend $10000 on a new one. My '05 runs great, has lots of power and great clutching (thanks to the S8X) but I am pushing almost 4000 miles. I know that there is going to be a melt down sometime in the future. Just wondering from those of you who have ridden the new '07 800R if you think it is worth the extra jack or if I should just upgrade the '05. The 151 hp of the '07 is tantalizing, but the 827 RK Tech kit claims 150-160 hp. I like the idea of a two ring piston in the 827 kit, but it would be nice to have a new 2 year warranty on the '07 also......What to do......What to do.....????
