@ Honda CBF: He's not considering 13/46. That would be too much and nor is a 13T clearly compatible. He's considering 14/46 which I have calculated before to be a bit on the undergearing side.

@ AshwinPrakas: Engine braking is well controllable and you'll have to gearshift accordingly. No, engine braking shouldn't have any adverse effect on the bike...
If you engine brake too much and too hard, your tyres might skid or in long term clutch plates are affected. That's it.

That modified Karizma you posted has "KRP" written all over it. It means the bike was modified at:

Kaulson Racing Products,
7/58, South Patel Nagar,
New Delhi - 110008.
Tel.: 011 25842215 & 25840741 Fax: 011 25841200.

However, deal with them at your own risk. Last time I called, they were not very polite. Other members have complained of their bad service and inferior products.

@ manewolf: Almost all Indian chain sprockets are made by Rolon and are quite durable. Chain strength is determined by its width... Your current setup is .428 which is quite strong already. A .520 chain sprocket kit (Pulsar 220/ 200, Karizma, etc.) might slow down your bike due to its weight.

@ sid_speedstakes: Please use smaller fonts. Also, understand that sprocket is NOT a power modification, its only gearing modification.
I mean, if you want more top end, you'll lose a bit on acceleration and vice versa.
That's gearing. You can't get both acceleration and top speed increase using gearing, ok?

Yes, K&N will be able to increase your power output. For your P220, you should go for K&N Filter model: BA2201.

pulsar 220 HELP !!

i own a pulssar 220Dtsi the new version 2011,well, the thing is that i have increased the height of my shock absorbers by getting it fitted with 2inch bits and the height has increased but i feel my acceleration and top end are been compromised.
Now,
i need to know if there are any performace mods i can do for my bike to make it have a great initial pick up and top end .
Change of Sprocket teeth's front and rear ?
and k and N filter ?
i am planning to take it for a long drive to chennai from hyderabad.
A QUICK REPLY WOULD BE REALLY USEFUL GUYS.

Hey dude , alryt k & N would increase my performance ,
Well,if i go with the 1 teeth less for the front sprocket , the top end is increased , and if i go 1 teeth more for the rear the acceleration is increased ..
We'll can u tell me the combination .. or things that can be done after getting my bike fitted with k and N ..

After getting it fitted with k and n , if i go -1 teeth for the front , does my acceleration Of my bike's gonna be like b4 ? with an increase in top end ?

I hope u got my point . What i'm trying to ask u dude

Bigger front sprocket = Higher top end
Smaller rear sprocket = Higher top end

Bigger rear sprocket = Greater acceleration
Smaller front sprocket = Greater acceleration

no bro, i ain't telling him to go with 46t rear with 13t front. I told him to try custom build 43t (post #417) as changing the whole chain set at very low mileage is useless (economically) btw, 14/46 seems good too.

yeah i got that buddy ...
We'll the problem i have is , i increased the height of my bike by fitting a 2inch bits to the shock absorbers , so the height has increased and the aliment rod which the rear wheel bolt and shock absorbers are fitted on , has gone low instead of being straight.as the height has been increased it pushed the aliment bar Downwards ,
now what i see is my chain is in a slanting position instead of being straight. if the angle of the chain b by default was 180 degress now it's somehere like 170 degress ,
I feel my performance has been compromised, it's not like it was before LIKE THE STOCK.
My Question is :
1) Can i increase the performance of my bike without reducing the height of my bike like i got it altered.
2) i would like to increase the performance with out any major modifications but simple and effective way's to increase Acceleration and Top end .

ROFL the message is long but i hope i'm clear ..

No. You can't increase both acceleration and top speed by gearing.
If you change both sprockets, one for top and one for low end, the result would be neutral- almost no change in gearing.

I suggest you understand Gearing by reading my 1st post here:



Also, for more power, do these:

1. Try power mods like K&N BA 2201 for that purpose.
2. Get Joel's silencer for P220, that will give both performance and mileage at once!

Gearing won't be able to help you with more power...try the various power mods for more power...

K&N filters, free flow exhausts, reboring etc etc depending on your appetite..

So u suggest that , k&N would help me increase power.okay dude ..
And one more thing , after getting it fitted with K & N should i do the up jetting done , if so can u tell me what size needs to be used and ,
how much wil it affect my mileage ??

Sorry for the ultra delayed reply. Going for ZMA's complete sprocket kit on Unicorn won't make it a cruiser at all . Its a combi if 40/13T. Regarding chain cover, it should fit in bcz its just the pitch not width which is bigger.

I don't recommend down sizing the chain pitch. (Personal opinion though no specific reasons). If you are ok then CBZ classic kit should be the best alternative for you. Use complete set of CBZ classic. If chain length is less then u may need to add 1 or 2 links.

Even after fixing K&N and upjetting,It will give you nearly only 0.3-0.5bhp max.So IMO,Avoid that mod and invest in something like FFE! Just my personal opinion.

+1.
And k&n lets some fine dust particle enter your engine.. So, robbing engine life.
(k&n is OT here, guys) so lets shift back to sprocketing..

Help with sprocket and chain

Hi guys, I need your help. I have a suzuki gs150r. The front sprocket has worn out considerably and need immediate change. It makes a lot of noises when i ride the bike. But the problem is the dealer is closed due to some dispute and i cant find spare in local shops as the road presence of the bike is very less. Please advice if i can use chain spocket set from another bike. I have not calculated the number of teeths as yet but i found the following info on the manual. Final reduction ratio: 2.929 (41/14). Drive chain r428, 124 links. I understand that changing sprocket teeth might affect the acceleration or top speed. Please let me know if i can use any other bike's chain sprocket set. Parts of all other bikes are available. Thanks, raj

under normal riding conditions what is the life of a pair of sprockets and the chain for fz?

what if i use yamaha r15 chain sprocket. It is (42/14) as per info on the first page of this thread. Will there be loss in acceleration or top speed. I am okay with less top speed as i mostly drive on bad roads. Also i think r15 has o-ring chain and probably a half chain cover. In case i can go for it, do i need to remove the full cover my bike has. Also i dont have any idea about the pitch of r15 chain. Please help. Thanks, Raj
