25% hike in power is very over -optimistic ,dont you think,i mean the max they would have worked out is a revisd back pressure and differed angle of letting out exhaust gases,...but would this hike power by 25% ???? ,i dont know,..what do you guys think ?Originally posted by biker boy View PostThey said a video will be uploaded soon, so that we can check the sound.There is a thin line between adventure and madness,...God must have made me myopic for a reason!!!

is that Approx 0.25% or approx 25%Originally posted by biker boy View PostChecked it at KRP, its for around 5250 and there is performance increase of approx. 25% with improvement in the mid and low range.
Without the ECU mapping I am not really convinced it can give such a substantial bump...
Calling Perf Tuners.... Can you comment!
@Praful... None of the tuned exhausts are road legal...
So for starters we know three 'Facts'
1) It will void your warranty
2) It will make the bike loose the Road Legal status (unless you plan to get it legalised as a needed enhancement)
3) It will make you poorer by about 6 grands

Even I believe 25% is too much, moreover I was more keen about the top end
, he said there will be 7-8 kmph difference. But this mod is majorly to improve the mid and low rev. They are also going to launch a ECU in the near future. Lets see who launches the ECU first KRP or DSG
One of the awesome feelings I had in my life is to see the world receding on my back mirror

has anone done this mod already,..same system is available for the karizma and pulsar as well from quite some time,..is anyone aware of a user?Originally posted by biker boy View PostThey said a video will be uploaded soon, so that we can check the sound.
also i am highly sceptical of their claim of 25% hike in power,..there only seems to be revised back pressure, that would be achieved from this,..that aparat,..the same system is on karizma,pulsar and now on the r15,..so its not tht it is a custom mod for the r15 exclusivelyThere is a thin line between adventure and madness,...God must have made me myopic for a reason!!!

Guys I dont know about the 25% power bump. But if that exhaust is louder than the stock exhaust - by louder i mean with a better exhaust note, not just noise; then that exhaust is a decent buy. It looks fabulously finished. at 5k+ its slightly expensive though. I always felt that the r15 was just too silent for its own good. Esp after riding an RTR fi.
Even the Yamaha Business head was impressed with the RTr's sound.
Also, the bike featured in the KRP site looks great. With the rear seat cover, and different tyres-nice tread, white wheels etc. It looks great!
Kaulson Racing ...... GO!!!!!!!!!!!! For KRPR.I.P kriss.

I don't think it would be illegal... but then the bump in performance is crap. It would be a free flow exhaust and hence a better sound and better mid range - assuming that it is designed well as it comes from KRP. That's it. Otherwise Yamaha aren't sitting ducks with designing the performance kit if KRP can bump the performance by 25% or even 20% of that with just an exhaust.Originally posted by prafultripathy View PostIs it legal?
PS: 25% gain is a load of crap!

Welcome to the club. I'm also waiting for some inputs on this. But AFAIK, this should be done by the SVC mechs. All I wanna know is something that they may miss out on&we need to keep that in mind.Originally posted by souvikb83 View Postcan some body help me through pics about how to check the tappets and adjsut it???i think for my bike it is loose.the bike no longer feels crisp on roads nowadays.Quench my thirst with gasoline!
