Few things i wud like to tell you Chinmay:
1. Air filter is new (3 months old) K&N.
2. I have told u before that i have upjetted to the ZMA's 125jets( which u told me is wrong fit) and Bajaj guy told me that the carb tuning is perfect.
3. spark plug cleaned recently using a spark plug cleaning machine.
so that makes it Valve clearance and timing chain tension and timing chain pad only and my extra heavy weight.

Thanks Chinmay: It would be nice if you post this on the common thread so that it could be helpful for other people also. here's the link

u said u will let me know the value of vale clearance. I am taing the bike to the service centre this saturday. According to what u say, i think even my weight is a big load. I am 90kilos bro.

4.Check for plug gap.5.Check the Air Filter.Some of the point I am giving u coz I have considered that the vehicle is not serviced. If u have recently serviced the bike then omit some points like plug cleaning and air filter cleaning.
Let me know......

well i couldn't find d thread in common blog. so will tell u here only.1.Check d valve clearance. Check the setting of valve clearance adjuster.(since d sound of valve & rocker comes A LOT,after heat.coz 3rd 4th gear means bike already ran 4 long time. This sound usually comes after hot engine & under load. If d cleanrance is wrong or gone out of recomandation. so check it n get it done from Bajaj Guy. If u want clearance value then I will check it tormorrw n will let u know.)2.Check 4 timing chain tension and timing chain pad.3.Recheck d carb setting. AF screw 2.5to3 full turns.(sometimes lean mixture gives problem,coz rider generally try 2 rev high. coz he is 0 aware of mixture setting. So high reving makes engine under stress,so becomes hot either.)

K bro no worries. I will post the comment in common blog.

I have posted this query on the Bajaj Pulsar 180 thread. I would love to hear from YOU specially. Could you throw some light on this issue of mine on the thread?

Hi Chinmay,
I have a small query....
My P180UG-III has done 18000km now. For the past 10000km i have been getting this knocking sound from the engine.. dunnno how to describe it... its like a fast repetition of this (katak katak) sound. How about the sound of nuts being ground in a grinder.. like that
I notice this knocking in 3rd, 4th and 5th gears esp in the 4000 to 4500rpm.
I am using a good synthetic engine oil for the past 8000km( not the same one-changed it twice)..
Could the experienced gurus out there explain what exactly this knocking is and how it can be rectified ( if possible).

HI Chinmay. I was about to ask u what ur profession was because u explain so much in detail. But I dropped the idea when i got an email from **********.in with ur article on high & low profile tyres. So ur profession became evident..!!
I like ur style of explanation.
