V-twin Help Topic Approved

Could you shed some info as what all went into that mods?

Good idea; why not? Anything's possible, provided the efforts, knowledge & time materialize together.

IIRC, P220 produces about 21HP, even going by theory, it can only become 42, then how is it possible for 50 bhp???

BTW, when you make one, do you think its possible to ride on the roads? Think practically before working upon this project, the effort is not worth practically.

I think more than one cylinder produces more power than a single cylinder of same capacity...

Like 250cc Ninja ~32bhp(2 cylinder) compared to 220cc Pulsar 21bnhp or 220 Karizma 17bhp, definetly the extra 30cc cannot produce all the ~12bhp difference, even though we should also regard the liquid cooled engine of Ninja.

there was a v-twin fiero featured here sometime back so i think that its possible

nice thought... somewhere on xbhp, someone is already building a twin engine... u can contact the group...

edit: the link is http://www.xbhp.com/talkies/pit-stop...in-850-cc.html

That's a stock 220 power figure. We can always tweak it by going for after-market performance enhancement kits(free flow exhausts,sproketting etc etc)

Why dont you go through my thread?


Yes, I know its time consuming and requires alot of knowledge, but its actually finding someone interested in such a thing.


I said 45-50, I should be running around 24-25 bhp, so didnt think a 440cc or so bike couldn't run that. There are race bikes with 250 cc engine running over 50 bhp.

Why would it not be? I didnt mean just to plonk in another engine and off we go, I meant as in the whole package, chassis, suspension, braking.
Also no where did I mention that I am going to do this, but I wouldnt mind.

Exactly, however, this would be a 400+cc 'Humara Bajaj' bike, so 45-50 figure would be enough.

That is what I have done.


Right now looking at the other V-Twin thread.

Although I do not have too much of technical knowledge about the thing, but Bullet 350 cc produces just about 18 BHP and oodles of torque. Power depends on the rpm as well. And, as far as I know higher the rpm at which certain amount of power is produced, lower will be the torque at low rpm, if you see the torque-power graph.

So, it depends whether the engine is designed to rev high or not. Ninja 250 may be able to accelerate very fast but it cannot pull more weight than the Bullet 350 because Bullet produces way more torque at low rpm than the Ninja or any other bike made in India.



So, if the engine revvs higher it can generate higher power. That is probably the reason why Ninja produces high power. I am an old man, so I dont know the data and I would not bother to look up the exact data on google. But Ninja probably revvs much higher (till 12,000-14,000 rpm) whereas Pulsar probably redlines at 9000-10000 rpm, certainly not more than that. That is why Ninja produces relatively much higher bhp whereas it may not be able to pull as hard at low rpms as a Bullet or other such bikes designed for low rpms. Engineers design engines differently as per the need. Those small engines producing high power are good only for racing, not cities where you will mostly be riding at low rpms.

if u ask me,a more relaistic approach is to enlarge the cc of ur present engine to 250 ~270 cc and change the required internals.. will be benificial,doable and also less risky.. maybe u can contact joel for some idea's..

An all new Motorcycle.

Where is Bajaj? Why hasn't a brilliant idea as this crossed their minds?

Hope you can finance them!!!

Hope my dear friend you didn't know about RTO, registration & host of several other process unless you intent to keep running your V-Twin Pulsie with a different entry in RC book.

Anyway, Good luck to you.
