Re: Random Questions regarding the RX series

condition of reeds,after cleaning them i reinstalled them,but now i can hear the sound of reeds flapping so should i change them with new one

Re: Random Questions regarding the RX series

Airscrew should be closed completely in clock wise direction. After that try turning 1 1/2 - 1 3/4 anti clock wise direction. Remember the turn is not based on the minus screw position but 360 degrees. Plus or minus half turn should find your right setting.

Hi
Does anyone has a complete list of all the rubber parts for the Yamaha RX series :

Re: Random Questions regarding the RX series

Gentlemen sorry to bump this thread. I need some advice regarding my 1996 rx 100. Am in the process of procuring spares for rectification and need to know what to buy. I hope senior members/ two strokers can help.There are three problems with my motorcycle.
1. If from start I try to engage first gear, on releasing clutch there is a loud clattering sound ONLY if the RPM is not idling. In case I engage first gear at standstill at idling RPM or close to it there is no such sound.*
2.* During the first start of the day the first gear engages with a jerk, occasionally stalling the engine. There is no problem in subsequent engagement of first gear in later starts, provided it is done close to idling.
3.* The last one is funny. My bike consistently starts on third kick with choke, and I have to tilt it slightly to the right for a moment as soon as the engine starts, or the engine stalls. Also, I make it a point to idle the engine after start for 10 to 15 seconds before starting off, but the engine grumbles for the first 200 m or so. Thereafter the operation is butter smooth. Subsequent starts of the bike are perfectly normal so long as not done after a long interval, in which case I have to repeat the drill.
To aid you all : My jet needle circlip is set to second position from bottom. I run factory standard carburettor and jets. I have tried setting the pilot air screw to fairly rich positions* but no avail. The carb with jets is gently cleaned once every three months in routine servicing. I use Motomix 2t through the autolube pump plus 30 ml to every tankfull and Motul 3100 20W50 in the transmission. The plug inspection reveals a perfect light tan colour without any pitting or damage* to electrodes. The bike gives an average of 30 to 35. Max speed is 100 kph.
I am running a stock non rebored cylinder and standard piston. Bike has done only 28000 km as the cylinder and piston kit was replaced in 2006 in YASS in banglore due to an engine seizure brought about because I loaned it to a friend for four weeks who ran it without 2t oil. I have since taken care of the bike and run in was done properly with varying engine speeds without overspeeding the engine. Subsequent use has been moderate, and servicings regular.
Four years back I purchased a car. Due to frequent rains/ high humidity car took preference over bike and the bike just stood in the garage unused, during this period. Recently around three months back I decided that I' ve neglected it for too long. Took it to a mechanic and got it serviced, the bike is running perfectly and smoothly apart from the issues I have outlined above.
It would be extremely kind if someone here could give me pointers as to what could be possibly wrong.

hi shaanbirdman, i had sent you a PM regarding your query ...please reply so i dont keep waiting or call me at the number i PM'd you

Re: Random Questions regarding the RX series

Hi Shantanu,
Heres what you can do. -
1. If from start I try to engage first gear, on releasing clutch there is a loud clattering sound ONLY if the RPM is not idling. In case I engage first gear at standstill at idling RPM or close to it there is no such sound.*

-- check your chain tension setting. Cush drive rubbers .


2.* During the first start of the day the first gear engages with a jerk, occasionally stalling the engine. There is no problem in subsequent engagement of first gear in later starts, provided it is done close to idling.

-- Are you clutch plates too old or do you keep the bike parked for long periods before starting? It could be because of stuck plates or bad clutch setting.

3.* The last one is funny. My bike consistently starts on third kick with choke, and I have to tilt it slightly to the right for a moment as soon as the engine starts, or the engine stalls. Also, I make it a point to idle the engine after start for 10 to 15 seconds before starting off, but the engine grumbles for the first 200 m or so. Thereafter the operation is butter smooth. Subsequent starts of the bike are perfectly normal so long as not done after a long interval, in which case I have to repeat the drill.

-- Your carb need to be tuned properly. On original needle and jets, the air screw in at about 1 1/2 turns out. Clean or replace the airfilter if needed. Also check for a worn out carb manifold. an airleak can cause the air fuel mixture to be very lean leading to problems starting and overheating.

Re: Random Questions regarding the RX series

Yamdoot. Thank you so much. At long last I ve got an informed reply to my query. I will be changing the clutch plates. My ex mech said that only friction plates need be changed, the pressure plates can be cleaned with solvent/sandpaper and reused unless warped or cracked. I want to know whats your take on this. I'd read somewhere that if I engage first gear, press the clutch and kickstart, that should free up the clutch plates in case they are gummed up/jammed. Thats what I do, but problem persists.
Carb tuning: I ve tried practically every sane setting of yhe pilot air screw, to no avail. Finally asked mech to change position of jet needle circlip to one notch richer. Could it be a problem caused by incorrect float setting?
My chain tension is correct as per spec. Any other reasons as to clattering noise on engaging first gear at non idling rpm? What please, are cush rubbers?

Re: Random Questions regarding the RX series

If your pressure plates are alright they dont need to be changed. You can just go for a new set of friction plates. mail me on [email protected] for which ones to go for and where to buy them from.
Incorrect float setting can result in the fuel in the float bowl getting emptied too fast leading to fuel starvation. Like i said earlier, get your carb rubber manifold for any cracks or airleaks around it. Ill tell you how to check it in my email reply.
Cush rubber is the rear sprocket rubbers inside the drum.

Good to have you back doc...

Ques about yamaha rx 100 ??????

Hie friends,
this is joy sen. i want to know whether it is possible to get back the back pressure from silencer, because in my city, there is lots of rx bikes roam around and
all they have a signature beat , except my bike. i have expense about 6 k rs. to get the back pressure as well as the signature beat sound ,but i am surprisingly not getting it. when i go to some good mechanic they all use to say change the block piston and you will get the sound as you want , but i belive my block and piston
is running on 0.25 bore which is recently done by me, so i think it is a very big problem for me as well.

pl help me guys i am wasting my money like hell, if you want to stop me then you'll give me a good advice.thanks in advance love you all.

Re: Ques about yamaha rx 100 ??????

Query Approved and Merged​

Re: Ques about yamaha rx 100 ??????

Why do you mean by this??? Back pressure is always there. I assume you are having a 100 and if its the beat that you refer to, you should get the original core. News ones sounds a little soft and you won't get the same beat of a typical old one.

Unless your current block is original, changing the cylinder will not bring the original sound back.

Re: Ques about yamaha rx 100 ??????

Thanks for your comment bro but, Actually few days ago when i had gone to mechanic with my bike ,i saw a yamaha rx 100 same model bike was there and i started the bike and that was the sound like dip dip with the great back pressure i have felt that on my legs as i was standing behind the silencer , i did the same with my bike i have started my bike and listened the sound there was no back pressure and no clear sound like dip dip. i asked my mechanic to take out the silencer of the that bike and when i apply that silencer on my bike there was no changes the sound was coming as same as with my silencer. then my mechanic said that changing silencer will not effect the sound of this bike you will have to change the block piston. now you tell bro what should i do ????? a very big question mark is hanging in-front of my eyes by the way jokes apart . now i really want to sell my bike and want to get a new one which has a good sound ( signature beat). if you can help me bro it would be appreciable brother thanks in advance....????!!!!!????
