With the R15 front you probably have the stickiest combination(ignoring the R15 rear for aesthetic reasons). Do give it a try around your favourite corner asap Though i must say the bike looks odd with the enormous Sirac and the diminutive Zapper FY.

Its stickier than stock, but will give way as at the end of the day it is more or less a button tyre, need more rubber in contact with the tarmac to hold on better.

2.7K, well if it was available at the cost at which I bought it in I would have ridden down to Hyd to get it!

You would need a gripier front now to keep up with the grip levels of the sirac.

I just saw one 150 in my office with it!

Even the IRC I'm running up front is a lot more sticky than stock, it manages to keep up well with the increased grip from the rear!

But with the R15 front and the Sirac at the back, John's speedo will surely show about 147 or so

somethin interesting happened

got a call from khivraj motors bangalore just now the pbk showroom askin feedback on the service of the bike done last week , i was surprised tht they are doin this which is pretty good told him abt the low availability of the stocks etc and he tol me he will call me in a while to check if the stocks required by are available hmmmm intersting so they are doin some kinda good work not bad at all ..... wat do u guys think ?......??

There is one sirac in my college on a zma. But it comes rarely. There are many many bikes with sirac in Hyd.

Well i kept only for about 12hrs & ran about 60kms with it. Did not tune it. But yes the bike was on the leaner side. Could see it in the spark plugs easily.
You can buy that locking thing at any automobile shop. Just ask for a intake hose lock.
Yes its easy to remove the air box. You need to open the RH side rearset panel. Remove the battery. Remove the intake hose & a few other pipes connected to air box & pull it out slowly.

Iam dreaming of elbow cornering already on the P220.

The rates have shot up for the Sirac.

Yes i need a better front now. My present stock tyre isnt able to keep up with the sirac & can be felt easily under hard braking.

My bike already showed 146 on the speedo with stock gearing. It hit the rev-limiter on 5th gear twice on a downslope on NH7.

Problem:
Was your tyre touching the chain cover? Mine was slightly touching it so i removed the chain cover. No matter how much i adjust the chain its still the same. I guess some alignment problem. Can a unevenly worn chain cause this? Acid had spilled on my chain due to faulty battery. Or a improperly fit rear wheel bearings? Need help!

guys i am having some trouble from last few weeks....

when ever i ride my bike around 30-40kms continuously...after some time my bike starts jerking as if there is no fuel in bike...

it also happens when i rip my bike hard....

what may be possible problem??

check the fuel filter happens if thts clogged get it changed !!

You and your speedo!

Never got to go all out, but the best I managed was 141 with the WildFlare in the front which shows about 2-3kmph lesser than stock, so must have been about 143-144 on a stock front tyre. But I felt it could easily show about 145 on my speedo provided I weighed a few tonnes lesser and dint have my camera bag

Nope, never had this issue with tyre touching the guard at all. If the bearings are worn out your tyre would have had a wobble, put it on the centre stand check if there is a uneven rotation of the tyre.

Even if the chain is worn unevenly it will not move in the left-right direction to touch the tyre, it would only more in a up-down direction!

^^^ my bike has been refusing to go above the 128 kmph mark for ages now

I remember you upgraded your tyres. What is the exact size of the front and rear?

PS: Whats the update on the UNI? How many kms run with it? Whats the state of tune?Any difference in intake roar/performance?

well ihave a 120/90 at the rear and the fz front tyre on the front.
she still accelerates well but is loosing the surge near the top end could it be tuning issue.

It's a Fuel Injected bike, what is 'Tuning' means for it??

A 120/90 means your bike is running taller geared and actually should hit higher topspeed. Plus I am not sure about the profile the FZ tyre forms , but I am guessing that it is lesser than stock that again should give you bloated speedo figures.

So going by these 128 means you really need to get your bike checked up.

Fuel/Air filters could be choked, and you need to check the state of tune after the UNI install. And then tune the bike accordingly.

Fi or Carb, tuning means the same thing only the procedures are different!

I still did'nt got your point. What could one play with a FI bike, is it related to adjusting CO ratio.

well actually the speedo undereads by 2 kmph on my bike due to the front tyre, i too feel that the tuning needs to be checked.

When one "tunes" a bike carb/Fi, they adjust the AFR. In carb its done via screws located on the carb and in a FI its done via the diagnostic tool.

I can't make it any simpler than this and still don't get what your confusion is

Then its forming a taller profile, even then your bike should do more. Even I have the 120/90 rear tyre and the bike manages 135+ with ease!
