Payback (in km) when you go for a second hand bike

I decided to go for a second hand bike as I do not prefer to go on a bike in city traffic.
I intend to use the bike for long distance drives on weekends. As you see in the calculations below,
one recovers the cost of a new pulsar in 24,500 km while a second hand pulsar's price is recovered in 16,000 km. The maintainance cost has been factored in the calculations ( it is twice the amount that a regular bike would have).

btw, I bought this bike from bike galaxy at basappa circle on lalbagh road. There are a lot of second hand bike dealers (agents in fact) near minerva circle and VV puram. The same bike would have cost be 3 to 4 thousand cheaper if I would have bought it from the seller directly. I had to pay 1000 Rs to the agent to buy this bike.
The agent gathers this bike from exchange melas, direct sellers, etc.
How far my calculations are correct?
Only time will tell :)

Bought a bike. Ready to go

The bike, a 2003 pulsar (non DTSI , non alloy wheels, non kickstart) cost be 28,600 (This includes 750 Rs as insurance, 1000 Rs as commission, 450 Rs as registration charges). I bargained with the owner o reduce the price from 29,000 to 26,600.
The odometer reading has been manipulated, so I don’t know how many KM it has run. No idea of the mileage (trying to figure that out now), the RPM meter malfunctions and the idlng RPM has been set to 4,000 (2,200 should be ideal).
Meter has started, and I am in the process of learning the bike internals at present. I intend to use this mike for long distance rides, and the target would be to make a trip to Kolhapur from Bangalore (600 km one way on NH4).

Actually, it is always better to buy a bike directly from the owner as you can save the commission. But you can do this only if you have the ability to gauge the condition of the bike and judge the price of the bike correctly. I feel that I paid a bit more for the bike (I had started with a budge of 25,000!), but since I have already bought it, it is okay.

Here are a few tips that I found useful:

btw, I bought the bike from Minerva circle. You will find a lot of shops selling used bikes there. Do check for the Road tax papers and the RC book before buying the bike. It is always good to take along a friend who is knowledgeable about bikes.

Yahoo Ad "Sense" screwed up

I come to office on a monday morning, log on to Yahoo Mail and notice something
different. The banner ad was in Chinese! (Could be Japanese too). I am trying to understand the logic behind being presented this ad! There are no Chinese e-mails in my mailbox, no Chinese girlfriends. The only thing that is vaguely related to Chinese lying in my inbox is the eBay correspondence about the purchase of a Mobile Phone (CECT make) which is manufactured in china.
Funny!

PS: I use google Adsense on my blog, and most of the times, the textual ad's that are displayed related to the context of the blogpost.
