  • My new RXG want help

    Hi,
    Iam a degree student from kerala.Don't know whether to post this in "help me" section or here.I recently changed my bike from hero honda Sleek to Yamaha RXG due to the interest in 2 stroke.I always liked a RX135 4 speed(tiger) and after a lot of searching,finally settled for a descent looking RXG.
    My RXG is 1997 model with recently rebuilt engine.Eventhough looking nice,it is giving me some problems.
    I have some doubts too.

    1. It is having a tung-tung sound from engine when decelerating.Mechanic who built the engine said this it is due to the loose between sleeve and bore.Is it possible?He said that it can be rectified by some screwing inside the bore.

    2. Evensome people says RXG are pretty well as other RXs,I experience a serious jerking sometimes when going with low throttle.It is not in my friend's RX 100.I have found in websites/forums that RXG is having a lighter coil plate.Can this be rectified.

    3. Will fitting a RX100 or Tiger flute make a different clear sound like RX100 in my G?

    4. Also I need to know the chain sprocket ratio of RXs.For RXG I found it is 15/37.
    I will ask about fibre reed valves and 5 speed gearbox conversion later. So friends, expecting your help & suggestions.

    Advice is a form of nostalgia.
    Dispensing it is a way of fishing the past from the disposal, wiping it off, painting over the ugly parts and recycling it for more than it's worth.

      1. It is having a tung-tung sound from engine when decelerating.Mechanic who built the engine said this it is due to the loose between sleeve and bore.Is it possible?He said that it can be rectified by some screwing inside the bore. - Sound from where? Hope he doesn't literally screw your bore. What size it is currently running?

      2. Evensome people says RXG are pretty well as other RXs,I experience a serious jerking sometimes when going with low throttle.It is not in my friend's RX 100.I have found in websites/forums that RXG is having a lighter coil plate.Can this be rectified. -

      3. Will fitting a RX100 or Tiger flute make a different clear sound like RX100 in my G? You'll never get the RX100 note in your bike at all.

      4. Also I need to know the chain sprocket ratio of RXs.For RXG I found it is 15/37. - Correct.
      I will ask about fibre reed valves and 5 speed gearbox conversion later. So friends, expecting your help & suggestions.

        I'm aware that RXG's had trouble with ignition timing & are prone to jerking while declerating; most of it attributes to it's static timing. Get a RDD CDI, that's the best solution I can think about now. I don't think it's related to the magnet (I hope you mean this when you said lighter coil plate)

        Stay off!!! First you LEARN, then get all your issues ironed out & then think about all these. Pls stop funding the mechanic with your Father's hard earned money.

        if I were you, I'd simply LEARN & restore the Rx myself. With this forum in your hand & with a right spirit to learn, I'm sure you can do it as well.

              I too own an RXG 97 model and have the same problem. Recently I dismantled the bike and I think my clutch boss was the culprit. It was in pretty bad condition. When decelerating disengage the clutch and check, but this is just a suggestion as this test alone will not be enough to rule out the problem. As the clutch is disengaged the load on the engine is off and the jerking may disappear.
              My bike had no jerking if I disengage the clutch that's why I gave the suggestion and when the engine was opened the clutch boss was in its worst condition.
              I have attached the picture of my clutch boss

                Hi Habin, am not sure where you are located in KL..but i would say like Aargee and Sriram mentioned to stay away from that mechanic as he could screw the bore of the bike...RXG had the problem with the flywheel and magnet weight not matching the weight of the crank for the 1996-97 batch and then they introduced this corrected as YEIS...Like Aargee mentioned if its looking good cosmetically and then you need to concentrate on the engine side...The sound you are getting could be anything from the crank out of balance to the gudgeon pin to the top end bearings... First open the head and understand what size piston its running....and also this mechanic who built the engine has not got it sleeved. If its sleeved then he might be correct the sleeves are shifting or the clearance is not proper due to bad sleeve job...

                The best thing to do is first do the above, then see whether the bike is overheating or is running lean. If so get a proper tune done up. Now to sort out the electricals the best thing is go for the 100/90 kit and the RDD CDI but again you need a good mechanic if you are not doing the installation to get it proper who understand timing the engine. It will improve the lighting issue, sort out the jerking and also makes your engine run cooler and you can do a proper jetting to your bike which will make it run even cooler and increase engine life...

                If you are in TVM then you can go to Hilton Yamaha and meet my friend Cydney and give my name as reference he will be able to help you..

                  Sound from where? Hope he doesn't literally screw your bore
                  Thanks for reply.Sound is from the cylinder.

                  Thanks for the reply.Right now,I can't go for RDD CDI.Will fitting an RX135(tiger) CDI rectify the jerking?It is minimum when idle speed is settled low. Iam not an expert in engine/mechanical mantenance(DIY),haven't opened an engine yet.The real problem is that engine rebuild is done by previous owner.That may be a partial ovarhaul.

                  I think the engine is running 2nd oversize.Will confirm it soon.May be sleeved.
                  The sound is present only when going without throttle/riding slowly.I don't mind current lighting as an issue.
                  Bike gets heated after a 15km continuous ride.Carburettor tuning is done.May be running lean.
                  Even if Iam not from Trivandrum,I thank for your helping mentality.

                  The bike covered only about 550-600 km after the engine overhaul as previous owner said.I will post the conditons more clear after sometime.
                  ride safe...

                      Turn The AIR screw in carburetor by1/2 turn (180 degrees)CLOCKWISE and see if the jerking goes...
                      Please describe the type of engine noise in detail.

                        Please let us know how the 2T oil is mixed either directly through petrol or through oil pump... If it is through oil pump check the supply of oil.... For engine over heating also check the spark plug and coil ....
                        For Jerking change the clutch bell it will sort out the jerking problems ... That is the main difference between RXG and RX 135..... RXG's do jerk

                        If it is a sleeved bore please replace that with a new bore... Sleeved bores will always create some problems unless it is sleeved properly

                        2. Evensome people says RXG are pretty well as other RXs,I experience a serious jerking sometimes when going with low throttle.It is not in my friend's RX 100.I have found in websites/forums that RXG is having a lighter coil plate.Can this be rectified.

                        Yes I guess using a RX 135's will solve the problem.... RX135 is the altered version of RXG the problems in RXG where rectified and came as RX 135

                        3. Will fitting a RX100 or Tiger flute make a different clear sound like RX100 in my G?

                        It will not make any difference even you fit a RX 100 exhaust the sound will be the same .... When you use RX100 inner core the sound will be sharper you wont get a clear beat as you see in RX 100

                        4. Also I need to know the chain sprocket ratio of RXs.For RXG I found it is 15/37.

                        RX100 - 15T / 39T
                        RXG - 15T / 37T
                        RX135/RXZ 4-Speed - 16T / 34T
                        RX135/RXZ 5-Speed - 15T / 38T

                          I agree with what Dinesh has mentioned ^.

                          I suggest you convert your RXG to RX135, here is what all you will need:


                          1. Un-Sleeved 4-Speed Bore Kit (4TL00) running on 0.25mm or 0.5mm "4Y201" ART Piston kit. If you have the money, go for a new piece.

                          2. As many have suggested go for an After market 90/100 Ignition Kit like Ravi-Nagesh or RDD with Iridium Plugs.

                          3. Get the RX135 CLutch Bell Assembly with Matching Primary Drive.

                          4. Change the sproketing to 16/34.

                          5. Regarding RX100 type sound, you have to change the entire exhaust assembly to that of RX100. New ones are not available, but you can source a used one.

                          6. Replace the entire CrankShaft Assembly (The one with original "2YA" Connecting Rod). Or atleast reset it or replace only the Connecting Rod (This is possible if the current setup is running on STD Pin).



                          It might sound expensive, but you will have trouble-free rides for next 5~6 Yrs. Collect all the spares necessary first & then find out a good Tuner (who has patience to listen to your needs) & get them fitted in front of your eyes.

                          Lastly, sky is the limit to work on 2strokes, but it needs loads of money & patience.

                          Good Luck !

                          Note: There is nothing wrong with the RXG CLutch Bell Assembly, its just that it is very difficult to source & even resetting may not give favorable results. Hence the next best option is to go for RX135 Clutch Bell Assembly. Kindly go through the below content to learn more about our RX Series:

                            I have tried varies pipes. For getting authentic rx100 note, none other than rx100 block may produce. Itnis not in the pipe but exhaust port opening. 135 exhaust is slightly bigger than 100 as we all agree, however, you may try and alter the core but when a 100 is kick started beside 135, stands no where in the exhaust note. To an extent old 100 pipe may give a close flavour. Tried and tested.

                              On my RX, I ve cut the flute less 2.5 inches for the crisp sound. Thats a unique sound that you will get only on 135cc RX engine. But if the same is removed on RX100, it will become much louder compared to RX135. I love the stock sound of RX100 & the modified sound of RX135.
