What to do?
I would probably flush the coolant. I ordered the Yamacool which is about $8 bucks at Apache Motorcycle off Power and the 60. It's supposedly a 60/40 blend with aluminimum engine protection specifically for the yammy. You'll need a little over 2 bottles. They may not have any over there, I know they have some at the Scottsdale location and they ship between the 2 stores all the time. I was told that if the bike sits the coolant can gel up and the bike will run a little warm. I figure for $25 it's worth not having to think about it.
On the center stand I would check the brake fluid, I took my reservoir cap off and looked into it for the front and the rear brake fluid you can see the resrevoir on the right. If it is nice golden and clear then great. If it was dark at all I would take it into the shop and have them service it because you don't want any bubbles in your break lines.
I would lift the tank and check the airfilter. I replaced mine at 8000 miles. I think you can go longer but I jsut wanted to do everything when I got the bike since I wanted to have my own maintenance schedule setup. A hotly debated topic is using OEM filter vs K&N or other aftermarket highflow air filters. After talking to several people and reading the forums I would stick to the stock filter. I have heard of the K&N causing the bikes to run lean and also causing a reduction in gas mileage.
As for cleaning I would go to the car wash and use the sprayers there. I didn't even think about the high pressure issue so I did use it a couple times but not right up on the bike. I would wipe down with a micro-fiber towels that you can get at autozone. The next day when it was all dry I would use the Original Motorcycle Spirits Polish & Cleaner. I would never spray directly on the bike but rather would spray on the microfiber towel and then apply, then using a separate towel I would buff/polish.
After polishing, I would go for a short ride and then when back I would use P&J chain lube/cleaner (blue bottle) to clean and lube the chain. It is recommended for chain health/longevity to clean and lube the chain every time after you wash the bike as the soap can begin to degrade the lubricant and get crud into the chain. What I screwed up at first is that I didnt' wipe off all the gunk as I was cleaning and lubing the chain. I found it to be a lot better when I would use another micro-fiber cloth to clean and lube the chain (although this could prove to be expensive I'm sure, LOL)
Here's a little note on the shops in town. RideNow will try to pressure sale you and rarely cut a deal. I like the guys at Apache Motorcycle in Scottsdale. The guys in the Mesa store are still pretty good but so much busier they kind of just don't care. Also Apache if you do your internet homework and tell them a price a lot of time they will cut you a deal.
Good luck man and have fun, I'm kind of jealous since I'm waiting for my bike to be delivered.
