Default Re: Ideal way to break in a Mobike engine?

Statutory Warning- Caution- Use your own mind and judgement!!
Author fo this post not responsible for any comments made here!!


To Be or not to Be Indian is individual's choice!!

But Buy Indian- Run it like an Indian!!

I almost second the XBhp article for all Indian makes of two wheelers- be it 2strokes or 4!!
But there duration for a certain kmms is a bit too long!!

What - not only me but other similar minded riders- have found is that when u take it slow thru the running in period segments, the bike does run in well but it kinda ensures more longetivity!!
Suck bikes are not able to do as high top speeds compared to bikes that have done similar total running in period but with a more steady increase in speeds with more no. of smaller 'km' segments!!
They also feel a bit docile in acceleration!!

personally, i would suggest that everyone- esp regular riders- stick to the instructions in the owners manuals!!

A point to be noted is earlier bikes were asked to limit speeds to 40-50kmph for the first few hundred kms!!
Bikes like the Pulsar and Karizma are recommended to start crusing at 60 it self from dayone in their top gear- coz hi capacity single cylinder machines kinda struggle at a higher gear due to low rpms!!

Note that earlier most bikes were 4geared and hence rpm at same speed was higher!
Now with 5th gear, the same road speed will see lower rpms!!
This makes the engine go below its power band and it struggles to maintain momentum or accelerate cleanly!!
(O/T- yes, most riders/drivers believe in quickshifting to top gear thinking that top gear= top speed which is true in way but ony when they have accelerated well thru lower gears to reach that top speed earlier!!
Result- dead throttle- long wait for speed to pick up- waste of fuel and curses galore)

here is how i would prefer to run in
I would prefer to steadily up the pace every 400-500 kms!!
also i would do abt 500-1000kms extra than recommended!!
Also note that this is almost impossible to achieve in City limits due to which we would take rides/trips out of town just for the heck of running it in asap!!

These are staedy crusing speeds with a variation of 5-10kmph while riding!!
as mentioned in the article, holding speed for too long is also not that good!!
the upper limit is the speed u burst accelerate with proper throttle control!!
say u are supposed to do 40kmph-
do few mins steady at 40, then increse throttle slightly to do 50, then release throttle to slow down to 35, the again pick up to 40 and hold!!
Repeat!!

The burst acceleration will start after u have at least 500 kms on odometer!!
Now if u have reached a stage after 500kms where u can do 60kmph odd, u dont burst to 70 or 80 from the 60 itself!!
u gradually drop speed to a lower speed than 60 u can steadily do in the top gear, look for an opening if not on a clear road, now pick up speed fast by judiciously opening the throttle till speedo needle touches that mark and gradually ease throttle to come back at the cruising speed in that period!!
On an open empty road with no vehicles behind, one can actually almost let go of throttle to slow down on 2striokes and ease the throttle much faster on 4strokes!!
Never hold it at the burst speed limit!!

period of break-in> avg Cruising speed with slow
+/-5kmph by rider, burst speed(Platina/Karizma)
100kms> 40/55 kmph max in top gear(as per make)
100-500> 45/60 max in top gear, obviously much lower in lower gears
500-1000>50/65kmph, with ocassional bursts to 60/75
1000-1500>60/75, with bursts to 70/85
1500-2000>70/85, with bursts to 80/95
Break in almost over!!
over the next few hundred kms, u can do higher crusing speed and burst speeds, gradually increasing it, till you get an opportunity to max out one day!!

AFAIK, Bajaj has mentioned only 1000kms running in their manual for Pulsar 180!!
I will recheck platina, Pulsar and Karizma manuals and revise the speeds by +/- 5kmph soon, if need be!!

Earlier, 2strokes were required to do 1500-2000kms of running in!!
Always done 2.5-3k per bore, how many ever i changed(i used to go out of town to some nearby place just to finish it!! also much easier to floow speed patterns on the open Highway!!)

A rider is only as skilled as the 'Kms' on his Odo!!
And not every rider can understand his machine well!!

RiDe fast, RiDe safe(wear a helmet and at least a denim jacket riding boots, gloves when u go for those speed runs)!!

RegarDs,
Bikey!!

(p.s. Sunny- I am extremely sorry!! i do not agree with your points!!)
