So, At what rpm does it do 60 kmph, in top gear?

Also, what's the silencer's state in terms of rust, leaks, etc?

hey mate..
i needed ur help urgently...
since today morning my bikes throttle response has gone bad n now it seems to be doing a top of 60kmph...
i try to speed up further the bike strts sounding like irs doin 10000 rpm..
i took it to the bajaj service centre d guys der are tellin me to get my clutch plate replaced.... am confused!!!!
i was supposed to ride tomorrow with some of my other friends...

The iridium plugs won't bring a noticeable change in performance. In fact, you might not even gain 1 PS ...

Their main benefit is efficient burning, clean emissions & long life...

We all know that the main performance/ mileage is still dependent on cc, fuel, its injection and oxygen mixed ...
A spark can only do a very minute change, which mostly is never noticeable...

i have sorted that prob i had with the engine..
i got the whole bore replaced..
also i am thinkin abt gettin iridium spark plugs on my ride..
could you tell me the difference it would make in my ride's performance..

Have you re-machined the head to match the new cc? Also, the gasket should be air tight upto high accuracy ...

Also, have you run-in properly after re-boring? Run in is necessary ... reply...

Bro, I don't have much experience about Re-boring, being in a small city... But, to say that reboring would cure the problem of engine sounding rough would not be correct.

In fact, reboring doesn't cure problems. In rare cases, it just causes more problems...

Engine sounding can be related to intake too. BTW one question, Did you try changing just the stock piston with a new stock one, before reboring?

In this problem, "Joel" would be helpful. Please send him a PM ... But, you'll have to give more details then this much ... like history, nature of sound, etc.

man i got a P180 UG2.
i got the engine rebored recently (it read 52300 km), due to the roughness of its sound and on advise of a bajaj service technician.
