is this usual having such a big difference ?

as i dont have a car shed , i park my cbc under the shade of a tree and cover it with a cover which i got on purchase time, and i don't think sun is eating up my petrol.

no petrol leaks, any chance for large opening and excess petrol vaporization through key hole?

The petrol tank cap has breather holes without which the petrol in tank cannot flow in to the fuel system..so slow evaporation is a possibility..Also remember every Internal combustion engine is a thermal machine whose efficiency increases with heat.So if you have start and stop drives of less Kilometers the bike will give lower mileage due to the engine ,requiring time to achieve operating temperature,at every such event.

Update the mileage after using 20w40 please. My xtreme mileage was as low as 38 when i was using castrol 20w40.now back to normal of 50kmpl after switching back to oem 10w30.

ohh god is oil plays this much milage issue. last time also i used 20w40.
my milage is 40-42kmpl max .

My doubt i read that some of friends here getting 50kmpl+ are they using 10w30 oil?

any change in Sound/vibrations ?? would suggest u to use rubber handle grip (in case u not using them ). Such a difference it makes on ur mind.Lesser vibrations are felt on ur wrist as compared to stock handle grip

at 60kmph now not feeling so hard. before oil change after crossing 55kmph feel a little more vibration. now cool after running 1kms

i checked every there, under the seat n tank, every tube ends, no petrol or even other oils deteced.

what will be the avg city milage for some one getting 55 on high way?

should i turn off the petrol on-off-reserv valve while parking for a long time?

If you get 55 highway you can expect 45 in city..It is a good practice to turn off petrol tap when stopping and parking bike for some time.

I used to get get 50-55 on long trips (<40kms) with 20W40 only with little lean mixture,now since i have tuned it to little rich i'm getting somewhere around 40 .

at 60kmph now not feeling so hard. before oil change after crossing 55kmph feel a little more vibration. now cool after running 1kms

20W40 is always preferred for long/high speed trips.only thing against it is Cold start issues which are present even with 10W30.so if u live in a place where temp hardly goes below 10-15 deg,use 20W40.

aside please confirm whether ur engine stalls suddenly if u r riding in neutral gear and suddenly apply brakes and come to stop ? me having this issue and cant figure it out why its happening ?

The thing is while in a long trip trip u hardly stop and continue ur ride in one go with most of the times being in higher gears,thus giving you the higher mileage.though for multiple short trips inside city requires frequent start-stops which'll consume much of oil only in start-stop process . moreover i cant expect 4/5th gear most of the times in city,so that is the reason behind this.apart from the technical point explained by PSR sir (reminded me of my collg mechanical faculty,everytime u have a problem,he APPEARS out of no'where and had a reason/solution for u. there should be a HATS OFF smiley in message option .

No way unless ur ride is leaking which ain't.

Got the 4th service done. Feels refreshed.

odo reading ??

Only thing bugging is the irritating tappet noise. The engine sounds perfectly fine when cold. But after riding some 10-15kms, its like coins put in a paint can.

SVC guys never get it right. Can't let local ones fiddle with it; they may not even know the correct clearance.
Whats the way outta here.. ?

I guess we all have to live with it.look for some loose metal parts which may be contributing to this noise(such as number plate,or horn plate or even crash guards bolts),2 of'em where loose in my ride

and believe me one doesnt feel much of this tappet noise while he's driving,isn't it ??? so just enjoy the smooth ride and ignore this tappet noise.u r nt the only one to have this

**abhisheklalnediya** · 01-15-2012, 11:24 AM

so i guess its not a problem to worry about

btw howz your milage

Odo reads 7.5K

And yea, it only audible when I stop at signals or go down an incline. Otherwise only wind

But a loose tappet aint good, is it..? It lowers both performance and economy..

as most of senior member suggest,tappets cant be lose in such short duration but cant say about everyone. Hopt its not loose on ur ride

,njoy ur ride and dont get disturbed by this noise

It defenitely IS loose for the past 2.5k kms..
Guess what, I am getting 40-41 kmpl on the highway, and in the city. Both the same.
What mileage do u get @ 70 +/- 5 kmph..? On the high way..

at max i get 55,dont get enough ride with 70kmph speed . its mostly hilly area.in city i get around 40-45kmpl.

I believe, If you rip hard all the time the tappets get loose withing 1K Kms. If you dont rip at all then they're good for 6k max.

Am looking for a detailed service manual, will post the exact interval after finding it.

Does that mean one has to check/adjust his tappets once in a 6K km for sure ,mine is alsmot 5k,shoul i get it check after 6K readings ?
