No I didn't find any problems with the suspension or with handling. Someone with more experience may feel a change in the handling, but I did not. My change was only 20mm at the rear seat, so it wasn't that radical. I ride a lot up at the Angeles Crest so the bike handles pretty well anyway. I just wanted to get my but a little higher when riding so I could have put on flatter bars but I didn't want to go that far. Very happy with the change. By the way, the bike has been in the shop for four weeks as when they installed the new clutch they didn't mesh up ALL the gears properly so when they tightened the basket they broke teeth from the oil gear on the generator gear and the oil idler gear. Gear between the oil pump gear and the oil gear on the generator gear. The dealer tells me that the generator gear is on the ship(from Japan) arriving April 4th. Another week to get it back to the dealer in LA. Then a few days for them to get everything back together.(Without breaking the gear again) Yes I am pissed off. But what can I do. I feel better now.
