It looks pretty level to me, and even if it's not, it's likely only a tiny & inconsequential difference, possibly caused by some 'not exactly aligned' panels or bolted connections put together during manufacture, or maybe even just due to the crappy tires these things leave the factory on!! Are you positive that your wheels & tires are truly 'round' & even? :dontknow:
So, all that said, if you are still concerned, it's probably time to break out a spirit level & do some checking before getting too worried - are you sure that the ground your Ryker is sitting on is level; that your (front) tires & wheels are actually round & inflated to pretty close to the same pressure; and that your shocks & springs are also adjusted correctly & evenly? If all those things pan out correct & level, then try getting the spirit level in to compare those frame lugs/brackets shown in your pics are level; and I'd probably look to compare more spots too - both the left & right inner mounting points for the suspension arms; the lower ball joints on each side; across the width of the swing arm bushes; the rear wheel hub.... anywhere you can check that has points that should be level from one side to the other, the wider apart the better! And I wouldn't worry too much about any difference much less than saaayyy, one half of an inch over points 6 inches apart - anything less could simply be due to the poorly constructed Kenda tires... I've seen lumps in the tread & out of round bulges in them that were bigger than that!! :sour:
But seriously, I don't think there's anything there to worry about. :thumbup:
