OK, I guess I'll go ahead and do it if a couple people had tighter exhaust valves. Probably I'll wait until 1000 miles though. The Grom is running great. I'm cynical about this though. It does seem a lot of what is recommended in the way of maintenance is somehow related to maximizing profits for dealers in some fashion. If you buy a car without free oil changes, they recommend one at 6 months or 3000 miles whichever comes first. Buy a car that includes free oil changes and they won't change the oil until you get 10,000 miles on it even if it takes 2 years. Here the idea might just be to get you coming into the dealership early on. Afterall, there are people who do oil changes if anything and that's about it. I plan to do everything, including mount and balance my own tires. My master plan is to keep the bike out of the dealership.
