Mate when you ask for help. Leave the attitude out.

The "I don't need lame response" could have been better phrased.

Thanks

Re: Power Upgrade For Honda CB Unicorn

Best of luck with your belief! You're talking about spending ~25k on hot rodding. Its suggested you do your research, gather the pros and cons.
Any hot rodded machine has "lesser" reliability factor w.r.t stock factory tuned bikes. Also, kmpl figures decrease and not vice versa.

Anyways, I'd suggest you to hot rod in stages rather than getting a full blown setup at once.
P.S - Your top end won't increase drastically, you'll only reach there faster.

Re: Power Upgrade For Honda CB Unicorn

All the best with your experiment, but try to research more before you do it.. Nothing is as good and as reliable as stock.. Few People I know have done the Joels Big Bore and they have reverted back to stock as they faced issues with the hot rod setup... one guy had blown off his engine too because of the Big Bore.. so think twice and if you decide to go for it.. go ahead...

Re: Power Upgrade For Honda CB Unicorn

In that case, you should be spending more time talking with the guys at race concepts (because of your belief in them)
you are better off getting the answers directly from race concepts.. than a few responses from guys here

Re: Power Upgrade For Honda CB Unicorn

@X-hawk what was the pricing list for a 165cc bore for the unicorn offered at Raceconcepts and what are the other stuff you'll be getting along with it, like exhaust, air filter??? Please let me know ASAP. . . BTW jus GET SOME OTHER BIKE for more power and I think you do nothing but spoil your bike if you do too much modification, , , Remember, anything done too much looks bad and doesn't last long, so just go for the next upgrade of 165cc or if you are a speed freak, just go for some other bike. . . If you need costume upgrades, I can give you some ideas but don't know too much in detail about performance upgrade. . .

Cheers!!!

Re: Power Upgrade For Honda CB Unicorn

I was planning to get the big bore done.. and it doesnt come with FFE.. FFE extra cost.. i was saved by [MENTION=41586]Divya Sharan[/MENTION]..

Re: Power Upgrade For Honda CB Unicorn

can you just tell it briefly, didn't get you properly. . .

Cheers!!!

Re: Power Upgrade For Honda CB Unicorn

When i say FFE.. It is the exhaust.. free flow exhaust.. i was going to get the joels big bore lit for my zmr but few guys made me realize my foolish decision so i changed my decision and stick with stock.. as i am not rich enough to afford to spend more money...

Re: Power Upgrade For Honda CB Unicorn

BB kit (Big Bore) contains a bigger piston with the corresponding head for the bike. That's it.
Apart from that, you'd have to replace old worn out related parts as well - camshaft, timing chain, clutch plates, sprockets etc to handle the extra surge.

Now, you'd have to get a FFE (Free Flow Exhaust) to attain the max that the BB kit has to provide.

But, you would need an aftermarket air filter too. Stock ones would restrict air flow. Hence, K&N or Simota.

Finally, you'd need a bigger carburetor to account for the extra fuel/air flowing in!

After all of this, the problem of TPS (Throtte Position Sensor????) would exist in most bikes and you may have to do a jugaad to fit it onto the new carb.

All said and done, you'd need to pay a visit to your mech more often because more often that not, hot rodded bikes run over the threshold limit of tolerance they were designed for.

Re: Power Upgrade For Honda CB Unicorn

Got It, if that's so then I can just go for a small upgrade like fitting a K&N filter rather than modifying and ruining my whole bike. . .

Cheers!!!

Re: Power Upgrade For Honda CB Unicorn

K&N would ruin the bike too, but slowly.

Re: Power Upgrade For Honda CB Unicorn

was on mobile hence could not explain in detail.. of course @Divya Sharan helped me out of it

----consecutive posts auto-merged-----

Riding the bike stock will keep the bike safe and harmless... whats the point in gaining a speed of 1-3 kmph which can harm your bike?? hope you can feel what I am trying to say... a stock bike can any time beat the hotrodded bikes in terms of reliability.. you won't have to worry about when your engine is going to blow off or when its going to give up on you

But again.. if you are going for KnN, you will have to upjet your carb.. meaning bigger jets.. bigger jets lead in draining more fuel.. more fuel drained means your FE will be in loss.. again.. upjetting used to be more like a trial error.. maybe now you will get the proper jets for the carb.. but 4 years back.. it was all trial error.. if you don't do upjetting.. your bike on higher RPM will be running out of breathe.. and trust me.. the KnN filter sound will be admired by you only for a max of 1 year.. and you will start hating the sound.. and you will want to fit the old filters back.. and doing all this.. what is the power you gain?? very negligible.. if you want to make you use of the KnN. you should go for the Free Flow Exhaust.. which is illegal in India.. so think wise.. save your bike from going to hell..

Just one question to you and those who want to modify their beasts..

would you like it if someone removes your small and large intestines and fix in a bigger ones so that you eat more?? or remove your kidneys and put in some other kidney just so that your blood gets filtered just a bit more?? I mean.. yeah.. it would be fine.. but the pain you will have to go through when you do such things..

Just a thought to think about.. Leave your bikes stock and ride them happily.. they will be loyal to you and won't abandon you.. If you know what i mean..

Re: Power Upgrade For Honda CB Unicorn

You may not like what I'm going to say, but I would best stay away from Joel's BBKs. Eventually your ride isn't going to last as long as it would have if it was stock. And add to that multiple visits that you might make to the mech for maintenance + the money and time spent. And like someone rightly mentioned before, if you believe in RC more, its best that you talk to them instead of asking opinions here, because you might not always get the ones that you will like to hear. I would personally stay away from RC, if you're interested in knowing why, pm me.

P.S: This is purely my own opinion. No offense meant to anyone.

Re: Power Upgrade For Honda CB Unicorn

Hi buddy, I have a Dazzler so you will agree that we have the same engine per se apart from a few differences (like the more aggressive higher lift cam shaft that dazzler has).

I got the 180cc big bore kit from Joel and well it went bust in 1600 kms. The reason was excessive lean AF mix, the fault was not mine and Joel never contested that. He agreed without any qualms to replace the bore with a new one, this time a 170cc big bore.

I have covered more than 7000 kms on the new bore. But the journey has been not trouble free. First of all the AF mix is STILL on the leaner side. Yet I recently did a 710 kms trip in 21 hours. So is the set up reliable? Not at all. For one, believe it or not, in those 710 kms my tappets went loose. I have to set my valve clearances every 3000-4000 kms because of the altered head. The engine runs much much rougher than what stock was. A guy riding a pulsar would never notice, but it will be painfully obvious to anyone riding a Honda. Yet I am happy because I definitely have more acceleration. But has the top end improved? Nope because I am still running stock sprockets.

So what is promised?

Better acceleration and top end power - True
Stock Like Reliability - Bullshit
Enhanced Fuel Efficiency - False (How the hell can you create more power from same amount of petrol? It is absurd. Sure some will claim its because of better combustion profile and all but that has not been my experience. On the plus side - No drop in fuel efficiency - it will stay the same).
Mod is Plug and Play - Technically - yes, practically - utter bullshit.

Extremevirus who has the fastest Dazzler in the country (0-60 in 3.5 sec, 0-100 in 9 sec) has done extensive mods totaling more than price of the bike itself and yet his bike has probably suffered in the reliability department. Blowing Rs10,000 on big bore will get you some satisfaction, but not what you have cooked in your head.

And Joel does not supply FFE for unicorn. The bigger carb he supplies does not have TPS which means confirmed knocking.

And please do not cite examples of modded CBZ, Ghost Apache and stuff. Those bike have been under the expert hands of Joel for ages. Most likely your bike will be touched by Joel for a day max.

Please do proper research before taking any step.

Finally my last word on the topic is this: Do you have excess money? Then buy a new bike for a daily driver. Mod your Unicorn inside out then using all the money you have. If you do not have the money then please do not fly so high in the air without the foundation of hard core research.
