Ok...got your point..every gear shift from 3.5k-4k and top speed 60 even at 6th gear..
Well, I had seen one guy here saying that after 1000kms, he ripped his engine on every gear to high RPMs...and his engine is very smooth now..
how does that help? Does he mean that he took his bike to 8.5k even on 1st and 2nd gear?
Also, I've heard not to keep bike at constant RPM for long time. This scared me more because despite riding an old P150 for 2 years i never knew this. Can anyone explain more about this? What exactly is this RPM logic?
Are there more such bike related precautions which are very important?

+1 to that... it's up to u how to do the run-in... but i thing i would say is that for the first 750kms u can even go up to 5k RPM... But the only thing to remember is that don't give more stress to the engine. i.e. at what speed or RPM u ride dosen't matters... but one must gradually increase or decrease the speed and don't ride always at same speed/rpm(vary the speeds)...

Moral: Any thing u do, do it slowly... consider the bike as a small baby... first teach her how to walk, then run, jump etc. etc.

Highways? My question is, people vary speed in open highways also? Just so that RPM doesn't stay constant?
Also, I've heard that we can lock the accelerator to keep the speed in control. Can that be done with R15? To keep it in control initially...

Run her in the city before 1st service atleast. You will get enough of varying speeds&also this helps in setting the gearbox well too.

Hmmm...will do that...
Any info about the locking of accelerator?
One more thing..this RPM varying thingy is only for the first 1000 kms right?

keep her within 4000 RPM, concentrate more on the RPM meter than your odometer. Change gears at the right time(both while going up and down the gears). Also, keep check on your wrist, reaching 4000RPM should also be a gradual process.

I guess this rule more or less applies to all sub 160cc engines in India.

Treat her well for the first 1000 kms, she will treat you better, the rest of her life with you. Enjoy.

Sticking to one RPM for long can cause engine glazing. Avoid that. Go through the range of the RPM for good break-in.

Yup this is wan't i meant...
u wrote in single line... i wrote it as an essay... LOL...

Look here.

Truth behind "Hard Break In"

This is an Attempt to reveal the truth of the old, MOST debated subject.
Whereas Hard Breaking "Logically appeals" having proofs.
Manuals don't suggest so.
Confused and baffled I want to know the truth and survey is the best way to do this.


Please post your answers this way

In this Format

Bike:-

Run In way:- (hard run in or acc to Owners manual)

Fuel efficiency (mileage/average):-

0-60:-(If available)

Top End:-

IF HARD RUN IN
Season of Initial kms:- The Season in which you ran the bike the Hard way
(winter/summer/rainy)

Last option may sound crazy, but Indian bikes are not liquid cooled, and
stressing engine so hard takes it beyond its cooling capacity.
And acc to laws of cooling it will affect the cooling time as well as rate..


No debates , Direct comparison

NOTE:- Please post the true and confirmed figures.

Topic Moved and Approved.

Bike:- Pulsar 180 UG3 2007

Run In way:- Hard run in

Fuel efficiency (mileage/average):- never more than 35

0-60:- not sure but my bike was definitely quicker than other pulsar 180's

Top End:- touched 130+ , have a KnN with bigger jets.

IF HARD RUN IN
Season of Initial kms:- around september/october

Now done 20K kms, at 16K kms my bike started loosing all the oil within 700kms, later it decreased to 200kms.. now i have changed my piston and valves, bike is returning a never before mileage of 50kmpl, just completed running in the engine with new piston, performance needs to be seen.

Bike:- Apache RTR 160 2008

Run In way:- Hard run in

Fuel efficiency (mileage/average):- 40 kmpl

0-60:- 4.7 Register in the Meter.

Top End:- 112kmph i always run out of road.

IF HARD RUN IN
Season of Initial kms:- Summer

Bike:- CBZ* 2004

Run In way:- Hard run in

Fuel efficiency (mileage/average):- 36-38 kmpl

0-60:- NA

Top End:- 105 kmph

IF HARD RUN IN
Season of Initial kms:- Rains.

I am writing this because Breaking in of both the bikes had different reaults due to the Different characters of both of them. One of my friend was also the owner of both the bikes simultaneously. After breakin of the CBZ the performance was definitely better than most other CBZ's but the reliability factor had decreased. Clutch plate, Timing Chain replaced in warranty etc and the engine lasted for only 60k kms i ran the bike for 80k kms without repairing the engine after 80k kms i sold it. Due to worn out timing chain tensioner the engine gave away.
But result with RTR was totally different because its performance is good and the vibes are way less than my friends RTR. I dont know how but my bike is smoother and when i drive slow the FE is more than 45 kmpl.

Bike:- Bajaj Pulsar Dts-Fi

Run In way:- A mix of MotoMan and Manual recommended running. Engine braking was heavily used throughout the 2K kms. Never stuck any particular RPM for long. Hardly Red-Lined the bike. First 300kms shifted gears at 4-4.5K RPM, then shifted at 6K RPM. Oil changed at 75, 300, 750, 2200 Kms and till this time only SVC centre Mineral oil was used. After completion of first 300kms, bike was taken on a 1000 km road trip and was ridden between 60-80Kmph for most part of the trip with short burst to 100-120 in between.

Fuel efficiency (mileage/average):- Varies from City to City for first 17K kms was in Chennai and mileage hovered around 30-33 Kmpl. Next 35K kms bike was basically based in Bangalore and was giving anywhere from 34-39 Kmpl.

0-60:- Dyno Indicated figures
3.6 - 3.8 Seconds for 0K-40K kms on Stock tyres
4.2 - 4.5 Second for 40K-52K kms on taller profile tyres

Top End:- Varies from City to City again, (Speedo Figures)
Chennai - 132 Kmph on stock tyres pre-17K kms
Bangalore - 137 Kmph on stock tyres 17-40K kms
Bangalore - 144 Kmph on taller profile tyres post 40K kms
Dyno Figures
0K-40K Kms on Stock tyres - 136-138 Kmph
Post 40K kms with taller profile tyres - 144-145 Kmph

IF HARD RUN IN
Season of Initial kms:- First 2K kms done in less than one month, and the climate varied for Summer type hot, to Thunderstorm rains, to Winter Cold.
