Pulsar 220 DTSi with R15 headlight

Iam thinking of a super modification for my P220 DTSi wherein I plan to fix the R15 headlight along with full fairings. I expect the bike to gain more top speed and control BECAUSE the R15 fairing (in R15), does a good job of aerodynamically cutting away the wind thereby not putting too much strain of the rider and net cutting down the wind resistance.

Will that work out ? Please opine guys.

This is how it looks as done on another bike.

Think about the poor engine or fit a radiator.

R15 is dynamically the most competent, not just because of its fairing. P-220's fairing is enough to cut wind. Its delta-box one the 15 which does wonders.

Any mods look OTT.

Bad Idea.

Spent 15-20k and your bike "MIGHT" go faster by 2 kmph over the previous top speed with that.

Aerodynamics is much more then a copy and paste job.

As pointed out by Sheel, major over heating issues!

Wouldn't upjetting and a few other mods help you push up the top speed more than a fairing?

With the current amount of braking power, I suggest you don't look for any further increase in performance.

Aerodynamics is not just due to the front fairing, the manner in which it is bolted on and other components add to the 'aerodynamics' part. You will gain nothing in terms of top - speed. If you really want something aerodynamic you will have to get a fairing custom made and then you'd also have to work around the engine being air cooled.

And you stand to loose out on the lighting front as well, so for night riding you will actually loose speed rather than gain

Agree DeltaBox is the real champion when it comes to handling in R15. what I felt in test drive of R15 (before buying p220) was that on highway (read straight line), the fairing, even at 120kmph cuts away the gush of wind that it doesnt feel that we are crusing at that speed, let alone handling. So I want that kind of a feeling with my p220. Recently I drove my p220 at 147kmph odo (slight descent on a highway), crouched to the max, but the strain my neck was too much :(
Agree to your point about over heating but then i intend to use for short sprints only and oil cooler will do some work right?

I dont agree with just 2 kmph dude. Bcoz => Some days I cant climb more than 135kmph on p220 when wind blows from opposite direction (and im not crouching) . some days i can easily go upto 140. and some special days when the wind is backing me (or a slight descent in the hgihway), i have taken my p220 over 145kmph ODO (crouching max as well). Iam not talking about true speeds, just for comparison. so im pretty hopeful that speed would increase drastically with a fairing change.

Can you put more light on upjetting plz. what exactly is done? wat are the other mods? But again read my response to first quote, i need that 'better' feeling at high speeds with less crouching.

That was a very good point dude. I didnt think of loosing my mighty headlamps

Aerodynamics in a Lab is a great thing to talk about, but in context to the driving conditions here hardly any noticeable gain. Modding the bike for looks sake is your liking but as other's pointed out the headlight of R15 is no match for that of yours. Secondly you will have cooling issues.

The oil cooler is for OIL and not for Engine, the engine is still air cooled, so you will loose on that count.

Now as for the pain in neck due to on coming wind, you can actually do a small mod by proving an additional screen to deflect air higher than the current. fabricate an adjustable one or try with 2-3 different angles. That should do the trick for you. My friend did the same on his bullet when he istalled a fairing for his bike.

When i saw the title of the thread i thought.. oh wow!!! but a fairing job again, if you wanna go fast invest in the engine, a flat side carb, with matching jets & a matching exhaust will kill the competion (if you have a carb one), if yours is a FI one then its a different story altogether

Sam, if you are really serious about modifying your P-220, head to Bangalore to Joel Joseph. Ten10 racing. He should have something for you.

The mods will cost, but your bike will be reliable compared to other mods and the performance gain will be evident.

I will let Praful elaborate more on Joel.

Can you put some light on these mods?

Anyone has an idea of such an expert in Blore?

Hi Sam

Maybe you can go in for larger main and pilot jets to ensure the engine gets enough fuel at the top of the rev range.
Your post mentioned your bike as the DTSi and not the DTSFi, so I guess this can be done easily.

I am not very sure if effective exhaust modifications exist for the Pulsar, but you can look into that as well. I think Proton has something in its catalog.

Praful made an excellent point about losing your projector setup!

The fairing swap seems more like a style mod than a performance one. But it is definitely your call.

Cheers!

PS: I think the flat side carb would improve response, but not the top end. Gurus?

I think the current fairing is itself good & don't fiddle with it. The only good thing in that Black Pulsar is the Monoshock. The rear is looking neat.

CHEERS,
