even if the rear brakes are not running tight , it must be problem of rear disc(not brake), it might have disformed, i am damn sure.....

Set the tappets on a cold engine, dont try the circus urself. head to the SC and get it done . Go there on a weekday when ther is no crowd and get it done in a relaxed manner.

If the tappets are tight , you could feel vibes and the engine does not build revs easily.

Check the RPM meter first , rev it to 9k on neutral and if it doesn go ,do other checks like ,
clogged filter,check plug gap.
Do this and lets think of something else later.
Oh yeah , check ur chain also, if its too tight or too lose , u aint gonna go fast

i think its impossible that your bike does 140 at 8k rpm.....its the problem with your rpm meter...

+1 ....... i too think so .... is the problem still lingering ? or is it solved....

pls stop this!!
he never said that he has done 140 at 8K, he only said that he had done 140 earlier..

@ all , if u cant help , dont bother posting.
Feels like ur just here to point at him prove him wrong , Make him apologise to u .
oly then will leave him.

Santa

hes saying that his needle doesnt go beyond 8k...and he has touched 140 till now...meaning 140 kmph at 8k rpm right???

dude...we are telling him that his rpm meter might be wrong...if that doesnt constitue helping...then what is it..

A few reasons why an engine will fail to rev freely
1. Clogged air filter and running too rich
2. Tight tappets
3. Wrong cam timing (unlikely in this case)
4. Tight chain (if its not revving thru gears)
5. low cylinder compression
6. High viscosity in engine oil

So do the checks in stages.
Set tappets when the engine is warm always. Cold clearances will vary and thats why new engines end up in trouble like this. Always, tappets have to be mandatorily adjusted after the first 500-700kms.

I have started to believe that it seems to be RPM meter after all.

I did rev my bike on Neutral, and it did cross 8K, but touched 9K max.. nothing beyond.. I'm getting more confused. Spark Plugs are NGK G-Power, not more than 1000Kms old.

I feel the bike is not revving freely, and then takes ages to reach 7.K and sycks at 8K. But my bike does 140 @ 8K RPM, looks like it's the meter after all!

Got to go to SVC.. let's see what happens.

I will get it checked as well, as it is I need to replace my rear disc pads.

As you mentioned the feelings are similar to a tight tappet settings. But it's also true that my bike does 140 at 8K.. so it looks like a RPM meter problem now.
On Neutral it does go to 9K (slightly short of 9K) but nothing beyond. Air Filter is cleaned (checked visually), Spark Plugs are NGK G-Power.. Chain is also rightly set.



Guys.. Peace! I think I did'nt clarify.. Yes my bike does 140 at 8K RPM.. it seems to be RPM meter problem after all. But again I feel the bike is not revving freely.

Thanks Joel. I need to check on problem 2 and 5 if it's the case. I don't think the Oil is the problem here, Motul hasn't given me a problem so far. My tappets haven't been touched so far..


@All, Thanks guys for your support. I'm heading to SVC on either Sunday or Monday (Diwali), and would be doing a run on Roller Bench, to check first. I will keep updated on it.

Will the bike revv freely if running excessively lean. So lean that the engine is gasping for fuel till 4k rpm.

I get little noise as if the tappets are loose when the engine is cold. After the engine heats the sound is gone. Anything to do with tappets?

Iam running very lean. The acceleration from idle to around 4.5k rpm is not gradual, progressive or linear. Shall i get the engine compression checked?

My bike is 16000kms old and i havent got the tappets adjusted yet. Shall i get them done?

Joel, what should be the clearance for a hot engine? When cold, intake is 0.06mm, exhaust is 0.1mm. (if I have not forgotten! ) What values do you suggest for a warm Pulsar engine?

hey guyz
just curious about valve clearance
as i m also facing the problem of hard revving in fifth gear beyond 7.5k rpm , and if the valve clearance is the culprit and if i get the valve clearance adjusted properly ,will the low and mid range also improve or only the top range(i.e. 7.5 k rpm ) will show improvement ?
thnx neways ! !
