Issue, should be sprocket. You have bypassed the average life. Get it checked.
If that does not resolve your issue then go for wheel bearing greasing else it might not be required.

yeap going to do those things for sure
can u suggest me any other ways to increase my scecondary gearing ratio
the v2 has 15t front and 47t rear sprocket
v1 has 14t f and 42t r sprockets
thats the reason why the stop and go of v2 in traffic is better than v1
can any thing be done to the v1 on this aspect?

1 question- Does few small holes on air filter box which make more intake of air can affect the FE. at what extent? as that can make good roar sound.

hm few small holes will affect the air intake
but not the fe
one more thing the holes should be above the filter
no where below the filter element
well i pesonally suggest
if u want performance and not sound
then go for k&n airfilter element which is a staight fit in r15 with the box shut
that way no sound and all performance

hey guys i just wanted to share another thing which i tried the sunday and it was really successfull
it gives u speed and sound and is not also very harm full to ur bike
u just need to go to the service center give the service guy some extra money and buy an old r15 air filter box cover
the rest is in here

the sound of my bike was awsome
again on monday morning i changed it to stock and went to work

Mark the date 15thJune 2013. Bangalore-ladakh-khardungla-bangalore.

Is it gonna be a solo trip or a group , i would love to join you guys
if not an issue , please share the tentative plan , i ll try to make all efforts to join with ma Rachel

PS: I know you have K&N filter on your machine and a holed air filter box, but still you cant do Bangalore-ladakh-khardungla-bangalore in a day

hahahaha TJ very funny. even if i have M2K also its not possible. Bhawnao ko samjho yaar aap. I will be starting on 15thJune.

PS i wanted to use FU for this comment but i recalled that i have iron b***S too so everything is possible :P .

Dude not nitro booster., only Jet plane would help me :P .

Anyways regarding the holes on air filter box - then do make holes on air box as it enhances the air intake but there is no effect on FE.
and if you dont want to get irritated by the K&N filter sound then better have holes on it(i do get irritated by the sound).

Bro, itinerary is done and almost whole planning is complete. no matter if I ride solo or in a group, in any case i will be riding. Anyone can join in to get Leh'd.

Do follow this thread for all updates : http://www.xbhp.com/talkies/touring-...3-planner.html

Nope. They have changed the sprocket size to compensate for the fatter rear tire. The increased mid range is because of the changes in the ECU.

> can any thing be done to the v1 on this aspect?

i believe the Daytona kit has different sprocket sizes.

I hope you understand what you are doing. You are increasing the air intake and expect that performance would increase. No doubt the exhaust note would be more appealing but that's all about the good part. Since, your bike is inhaling more air but exhaling same as before(no exhaust change) and no CO changes in ECU, you are running your bike much more leaner and hence reduced performance. Experiment is good but this is just one half of the complete change. See other videos from the same channel, where they upgrade to FFE, Daytona ECU and Camshaft for proper boost.

I dont know why Yamaha didn't choose Roto Pedal Type Discs. It would have been cool and would have Better Heat dissipation. Rear Disc has got very less stopping power and it gets even worse when it gets heated up

What gave you the idea that petal type discs gives you better heat dissipation? The reasons for using petal type breaks are 2 fold and neither of these is to do anything with heat dissipation. The first reason is to reduce mass, whereby reducing the gyroscopic effect thereby facilitating in making faster direction changes. The second reason is the petal shape helps clear mud and dirt from the caliper. Braking power in both types of discs is the same.

The Rear disc has enough stopping power. I have never had any problems with it ever over heating.

its by design.
i actually got a mechanic to make my rear brakes 'weaker' to prevent it from locking up easily.

remember its the front brake that stops the bike.

the rear brake is only useful for stopping the bike at slow speeds (at low speeds its smoother than using the front brake).
a little bit of rear braking can also be used to keep the bike stable while braking.
if you don't ever use the rear brake that's ok too but do the opposite and you are screwed (sooner or later).

If it helps in reducing mass and help in change direction faster.More importantly it looks cool

why Yamaha didn't use it? Who knows

.. I dont know whats wrong,My pads are perfect and no oil on disc... Maybe thats the stopping power it can produce... But i drove NS and its rear Brake is really sharp,Stops like front

Cheers

This is my personal opinion; The R15 is the best handling bike in the country. It is already nimble and flickable. The question is 'How much more flickable can it get with petal disc and at what cost?'. Every street bike is a set of compromises. There are a certain set of trade offs made for various reasons including cost, design, regulation based issues. If I were to go by your logic, we should all be asking why Yamaha did not use Upside Down forks (USDs) as these reduce unsprung weight and increase rigidity and radially mounted calipers as these give superlative braking feed back and performance. The reason is cost.

Get your brake lines checked and have them bled properly to ensure that there is no air in the same. One worthwhile upgrade to consider is to replace the stock brake lines with steel braided brake lines like HEL lines. I have been using them and they are fantastic. My front brake is so sensitive that a two finger touch will start the braking.

Ah! so this is what its about. why bring all this technical stuff into a pojer question? :-)

i got a cool idea. why not install the r15 front rotor and twin piston caliper on the rear wheel. that will surely give solid stopping power.

Hello everyone,
As i was called by SVC manager to show my bike for that tiktiktiktiktiktiktik sound.
IF they want to open up my engine or wants to set the clearance of valves, shall i allow them?????
what measures should i keep in mind to tackle them as those people always blame vehicle owner for problems.
like i got a bent handle "T" which was bent towards right side,I informed them on first service as i understood the bike
after 200-300kms and came into a decision that "T" is bent,The manager said," U have to pay for getting it center,
because it can your driving style which made "T" bent and now same manager called me when i complaint yamaha about
the sound coming from engine and asking me to show them my bike again.
So now i cannot hope that they are going to help me any of the way under warranty
