I 'm a fairly new rider (2 1/2 mo.) and I just replaced both the tires on my 99 SV650. I went from the stock metz that were on the bike to the Dunlop B220. I didn't change the tire size, the bike was dropped but that was at about 10mph about 2 months ago. Now it seems as though the rear of the bike doesn't turn with the front of the bike, like it's lagging behind. I check the tire pressure regularly and it's normal. How do I check the alignment or should I just take it to a shop?
