    Hehe, thanks man, don't worry I checked the manual before I told him anything. Finally decided to get it in next service. (3000kms is taking a month for me, give or take a few days)
    And good to hear you're goin strong on 15w40, the one im using now is 5w40. Lets see how it fares in the long run.


    Someone was asking about speed .. I seem to remember hitting 91 in 3rd, 106 in 4th, don't remember 5th, sorry

      btw...your looking for better pickup or top end ?
      Top end. I am a highway cruser. I need good speed to reach destinations at lower rpm without over doing my engine.

        your attempt was absolutely correct by changing the front to a larger sized one...
        dont know about bangalore..but in Karol Bagh..here in delhi..the auto market...the guys have loads of variety of sprockets...we can also get the custom chain set made aswell (front+rear+chain )
        I did the same for my first bike
        Just because you haven't seen it doesnt mean its impossible...expect the unexpected.

        • i rode the bike for about 35 kms with the altered gearing ( rear sprocket FZ). The gearing has become really tall. Im doing 100 kmph @ 6600 rpm, instead of 7000 rpm.

          1st is good till 40 ( dint redline any gear), 2nd is good till 50+, 3 rd easily goes 80 plus.

          To keep the momentum going i need to shift into 5th at about 100-105 from 4th, and then 6 th can be used from 90 odd, but should be shifted in around 100-110.

          Its good for touring, and steady long distance cruising @ 100-110 kmph, reducing the stress a little on the engine. But i would advise doing it single only, not with a pillion.

          Also i feel that you can pull gears longer, and hold onto a gear for longer period of time while taken curves. But the fun is in the first 4 gears only. 5th and 6th act like overdrive.

          I am still to check if the top speed has taken a toss due to the additional load of the gearing. Ill check tonight on the way to work and back and report.

                1.Excellent Yamaha,Andheri or
                2.Yamaha Factory Shop,Malad

                i did my 1st 2 service @ Geet Motors,Borivali which is a new authorised branch.They were dissappointing........
                Guys..pls help
                I was recommended the yam service centre at malad and have had no issues with them except that everyone goes there so you have to book an appointment by fone 2 weeks in advance,served coffee while you wait for piking up the bike later.
                I drive down from colaba to malad for servicing.

                • Alright, this is my feedback.

                  I paid closer attention to the gearing, and this is how its like

                  1st- good till 40
                  2nd - 60
                  3rd - 80
                  4th - 100
                  5th - 115-120

                  Then 6th. So its like in normal riding, 6th hardly is coming into play, as i fear stressing the engine too much when i shift into it.

                  - The bottom three gears with taller gearing make shifting and holding onto a lower gear thru a curve much fun. Its more fun to be close to the redline @ 50-55 kmph in second, than shifting upto third and not being able to hold the power ( for eg, at a round about).

                  - The top speed that i would get has fallen by about 4-5 kms ( earlier where i would hit 132, i was doing 127-128), but if the bike is kept in 5th ~ 115-118, the lack in acceleration is noticeable only in 6th.


                  - So overall i would rate the experiment a 50% success, giving me better drivability in the low end of the gears, but affective top end.

                  - Cruising has become really easy with 110 coming in at 7200-7300 rpm. I could stay in that zone all day.


                  - I feel the ideal situation would be to have a 41T sprocket, that gives a bit more acceleration and more usability of the 6th gear in city. Moreover this setup ( 40t rear) is not recommended for two people riding, only for single.

                  • The sprocket sizes will be in your owners manual in the full vehicle specs page. I need to go back there and get it fixed.

                        for your first post..would like to tell you that the 5th and 6th gears are both overdrive even in stock condition

                        for the second post...i seem to be confused. The rear sprocket you changed from 42T (stock) to 40T (from FZ i assume) should increase the top end. consudering you said that the gears pull over longer range of speeds, i think the top speed should have increased aswell.
                        can you clarify me on this please ?

                        • first statement - 5th and 6th in terms of ratio might be overdrive, but they still have some pull in them in stock condition. What i meant by feeling like overdrive is that you can sustain the speed you have, but acceleration in 6th takes ages, thats like cruising in the higher gear to conserve engine and fuel, but not getting enough acceleration.


                          Second statement - the gearing has improved, but the bike simply does not have enough pull to handle the taller gearing. The engine runs out of steam to pull the bike cleanly above 8000 rpm in 6th. i took 5th to about 121-122, and then shifted to 6th, the going to 127-128 was much slower than before. maybe with a open enough highway you could go for a higher speed, but the engine should have the pull to do so, which i feel it lacks, maybe with joel's exhaust, and a few tweaks here and there, i might be able to pull a higher speed.

                          Also the bike is 300kms from 8700 kms, due for service, and the tappets have to be adjusted. I want to try a higher C0, like i do in winters, for better low end grunt ( 4-8k rpm). That should improve the pull of the bike in higher gears.

                          • ^ JD - Can you redline and tell the max speeds in each gear ? Especially 3rd,4th and 5th.
                            Also when shifting from 5th to 6th, make sure you red line the bike first.

                              doubts cleared for the first point
                              just to confirm about the second...you mean to say even though on papers the top speed should increase...the engine has trouble pulling it at 6th gear..so thats why you managed a lower topend mark on the same strech..?
                              so does this mean that if given the length...the bike should (ideally) manage a higher speed limit...right ?

                              • For general Information, the R15 has a 14 teeth front sprocket, and a 42 teeth rear sprocket.
