I just got a 1984 GPZ900 Ninja. My front end was lowered 2 inches and it spins instead of coming up as well. This is an incredible bike though. My first bike was a 2000 Yamaha R-1, my neighbor had this one sitting in his garage for 10 years, perfect shape, still had the stock exhaust and springs. The lowered front end deffinately makes it spin worse, you can sit back on the seat and pull wheelies fine, but I would suggest fitting a slightly larger / stickier tire on the rear. I will be doing that soon myself. The tires on this 130 x 18 x 70 arenĀ“t really good performance tires by todays standards...
