    Appreciate a quick response , I cant wait to fix this... Than you!
    The pulser front sprocket won't fit in ZMA, you have to get the ZMA front sprocket.
    The P200/220 carb/220 FI back sprocket is a direct fit in ZMA, but you will get a slugish start and a slightly better topend and highway FE.
    You can get the P220 O-ring chain and some extra links which is better than ZMA chain, you can open the chain cover also but I won't recommend that

    EDIT: If you need a slighly better initial pickup and not the top end, you can go for HH ambition rear sprocket!!!

      Thank you for the update Amit. I went through the entire thread. Oh was not aware of the Ambition part. And opening the chain cover is not a problem , its open for last 5 years

      BTW I settled down for a aftermarket chain sprocket "ASPL" 13/40 - 550 rs
      Bike is getting serviced, will update you guys by eve.

        I had changed the rear sprocket of my Unicorn from 43T to 38T, thereby making it a fantastic cruiser on highways. However, in the city, its a pain to ride in the bumper-to-bumper traffic and is unable to generate enough torque even in 2nd gear. I need to downshift all the way to 1st gear even to cross speadbreakers.

        I am planning to move it up to 40T. The 38T that I am using right now is from the Ambition. Will any of the Pulsar sprockets fit the Unicorn or is there any other bike with 40T sprocket?

          hey guyz, i have reading the first 11 pages of this forum , and nobody has said anything about the fiero/fierof2 sprocketing!

          Well i have a fieroF2, it has a 13/40 sprocket size.. i am going in for a chin sprocket set change. i was thinking of using the Apache RTR180 set which has a 14/46 sprocket size. Should i go ahead with this setup?

            You can put 14T front of CBZ / Ambition. That is similar to 15/41 combination. 40T of ZMA will fit but chain will not fit due to the difference in pitch..

            I think Gixxer can tell u better on this. Check with him in Fiero thread. IIRC Abhi had changed his front sprocket to make the gearing tall.

              @Shreeni : Instead of fighting with the pitch differences of the Unicorn chain and the ZMA sprocket, I thought of changing the entire sprocket+chain set to that of the ZMA, including the front sprocket. Do you think that will fit inside the chain cover of the Unicorn? If so, I want to try that. Currently, I have the stock front sprocket of the Unicorn which is of 15T.

                looking for a 45t or 44t rear sprocket for r15

                i want to increase the accl. of my bike at the loss of top end but i am unable to find a direct fit for my bike can the sprocket be made exclusively at a automotive workshop? or the sprocket from which bike will directly fit into mine.

                    In delhi there is a place in karol bagh where you get sprockets without any holes .. you can get hole drilled as per the hub of wheel. First I would suggest you to try a bigger front sprocket to increase the initial.

                      Bigger front sprocket kills the initial It will increase the top end only.

                            Your R15 has a stock setup of 14/42 teeth. To increase acceleration you need smaller front or bigger rear. As far as I know, a bigger rear sprocket was available with the Daytona kit. But its expensive and not available separately I think...

                            I suggest you TRY a 13 teeth front sprocket from Apache RTR 160. And keep both bikes' different sprocket nuts and bolts ready, because either one should fit your bike...
                            And let us know here what happened here.

                              https://spreadsheets.google.com/spre...EzMnc&hl=en_US

                              Hi I have put all 3 types of front sprockets and tested fuel efficiency.
                              13T 60 KM/LIT
                              14T 67 KM/LIT
                              15T 71 KM/LIT

                              RPM maintained between 3k to 4k

                              15T @ 80-90 km/hr i got ave of 40 km/lit

                              my bike is 2k old approaching 2nd service maximum i ripped is 106km/hr thats what speedo shows

                                Nice Archive!

                                Hey, this was a very nice and educating archive (like many on this forum! )

                                Thanks for the information.

                                I had two queries:

                                1. I agree, with gearing, we are just choosing how to channel the power our engine is generating.
                                but, then, by gearing - what component are we stressing more (than the usual/stock setup) ?

                                My first check box is against engine:
                                If we are overgearing ( aren't we stressing the engine - if we drive with styles identical to our stock-setup-riding-habit? )

                                How about the chain-life with changed sprocket(s)?

                                2. Long term benefits/problems or sprocketing?

                                I already see, with overgearing - better mileages at same speeds (as before - but as it is achieved at lesser "rpm" of engine ).


                                Thanks,

                                Ace.
                                I wish, I would be paid by the word! :p
