Getting the chain tension right, as well as making the semi-famous TPS adjustment, really smoothed out the throttle response on my bike.
I’m about ready now to swap the stock Dunlop D220 tires for some new sneakers (Shinko). At 6200 miles, there’s a lot of tread left, but after 4 years, I’m thinking they should be replaced anyway. Yours could well be at the end of their useful life anyway (I’ve heard of people getting as little as 6K miles out of the D220s). Tire pressure should be 33 in front, and 36 rear.
