Splash,
As costly as it may be taking it to the dealer for the first two years it may be your best bet.
Suzuki tried to have me when there were non-genuine Suzuki parts on the bike, the dealer I bought it from serviced it! The bike then died two weeks later and I was facing the bill for a new engine until the receipts came out that stated what had been put on the bike.
I know Honda's are nigh on bulletproof but be wary if you install something that isn't manufacturer approved it may bite you hard in the pocket. As soon as it is out of warranty then do as much as you can yourself because it does save a fortune.
