Query Approved.

its a new engine(under runin) so will heat more frequently, so no need for worrying for it..

^ heating has got to do nothing with a new engine!

adarsh : switching to speed / power / premium wont make a difference - if the bike really is heating up

Too lean a A/F mix can make a bike overheat . check it

a newe engine heats more than a older one???

Why in the world will a new engine heat more than an old one?

Air fuel ratio to lean .
Check the air screw pos

OverHeating

As per the description by you. All the air cooled engines requiered AIR to cool since you are riding your bike in the traffic in 2nd or 3rd gear with the RPM of 2500 to 3500.
1. 3rd gear, that means you need to control the bike with partucualry releted RPM.
2. Heating depends on load. (In first gear, continues riding means over heating issue. second slight less heat, third more less becuase till the time u have enough speed, forth gear means you have already with good speed n fifth is overdrive so speed, rpm and cooling is in ratio.)
3. In the traffic moving in 3rd gear is possible but lack of air for cooling.
4. try riding your bike where there is no traffic it won't heat.
5. Heating also depends on oil level and grade.
Since you have just completed your service then it is possible that your carb may be too much lean. general best ratio is 14.7 at AFR. Or 2.5 to 3 turns of AF screw. (if you feel moist gas from exhasut tail then no need to worry.)
Air cooled engines need air with with good quantity. Less speed with third gear means already in the load.
If the atm. temp. is higher side then that is more problematic. That adds more temp. Some times petrol quality also makes huge differance. Please check the quality either. Adultration increases the heat drastically.

so I feel first change the fuel (but normal unleaded only) and try to ride your bike on empty roads.

Correct me if I am wrong.....

Why in this whole world people add this blister line in last!!

"Its fine if ur confident, that dosn't mean u shuld make other's feel ur overconfident!!!"
Someone wrote this while "quoting" the line!!

No offences to you brother, just recollected the pharse when saw that line!!!

for me there is a reason...but anyways...don't worry no offence at all..

Because, all the moving parts have tighter than optimal clearances. Excessive friction generates excessive heat directly and indirectly. Directly due to rubbing of metals and indirectly because the engine has to work harder and overcome the friction.

Its a known fact dude!

Though u explained all that in a superb way!
Clap! clap!

In Chennai, You can always feel excessive heat bro ...Ok, jokes apart..
I think the reason might be the thing said by abhijeet080808

generally it should happen for the first 1000/1500 kms or so. Check your engine oil condition and level. Is the oil level ok? what is the condition of the oil. A lower oil level will/can also cause an engine to overheat. Can you compare it with any other bikes available??? ie FZ or some other bike??? maybe its normal and you are overfeeling it?? lol no offense just an idea. But check the oil.
