hey bro thanks for the reply.bike has done around 45k or so.the noise is coming from the left side of the bike somewhere around the engine head.its a bell cling type sound.the sound comes only when running at speed of around 70-80kmph and after tht no sound comes.also the sound goes off when the throttle is slightly released.
am really busy till next week and so cant visit the mechanic.is this a serious problem??

You should be actually running a 2.75 in front or rear to eliminate the your front wheel sliding tendency due to contact patch misalingnment during fast riding.

man ur bike is very neat n well maintained....wat size are the rear wheels??16"??also wat tyres??front tyre is mrf zapper??

BTW guys ,as u guys might know ,i have a 98 rx135 4 speed tiger,with expansion chamber...
last week i jus decided to check the fuel efficiency of the bike...the bike did 49 kmpl even with late nite rides above 80kmph .....also its the best mileage i have heard for a rx with expansion chamber....i use CASTROL JETX oil in the 2t tank....don know the tyre air pressure though....
my bikes running on mrf motod 3x18 on rear and mrf nylorib 2.5x18 on front...as front tyre is stock tyre,i guess the odometer reading will be correct....
now is there any problem with my bike ??because i heard tht rx returns such gud fe only when the engine is running lean and it will damage the engine...
in my case the engine performance as usual is superb....does 80 in 3rd gear...also no excessive smoke....
so tbhpians pls tell me whether there is any reason to worry??

back tyre is MOTO D mounted in a YEZDI's rim and front is pulsar's Zapper

Hi Yamaha Lovers! Guys i just want to know how i can increase the pick up as well as top end of my rxz. actually i dont want porting the bike as i have heard that porting reduces the life of bike. can you tell me who can do the job in bhubaneswar. as far i know here in bhubaneswar the mechs just know to work on stock condition. i mean they just know to follow the company specific work. they dont know about how to increase the performance of a bike. any idea??? please help me out!

[invincible7]

@Rajeev... porting if done by a good mechanic or tuner wud never ever reduce the engine life... this is a common misbelief about porting.... i am sure tectrac can give you more reasons on the same... for increase in performance apart from porting (which u at the moment dont want to go for).. try to add a better carb.. ie.. flatside carb or if u can source an RD Carb.. but you wud need to time/tune the bike correct..with correct set of jets... also you can add a Uni filter.. it helps in better breathing and last but not the least an advanced CDI...

[Rajeev29]

invincible7 can i purchase these things from any online shop, as i dont't think these parts would be available in bhubaneswar.

[invincible7]

RD Carb... you can try checking the local market or garage if they have one.. for Uni.. you can definately order online. If you have RXG 135 carb you will need to check the diameter of the carb and then put a request online to get the correct one. Instead you can contact RDDreams.com.. they source the UNI's and the Digital CDI...

A mild port job cant really shorten the engine life if done by an expert.

You need to have a OE crank that is new and use only top quality 2T oils.... my favourites are Veedol Take off and Jet X from Castrol.

can a mech of yamaha showroom can do this job? i mean the first stage of porting? actually i know the head mech of yamaha showroom. in bhubaneswar there is no good mech who can do this specialized job.

They make a mess of it.

Better you get yourself an electric drill and a conical HSS grinding bit from Totem and just a couple of mm from the top of the exhaust port without altering the overall shape and proportions. Taking off just 105 mm should be enough.

Good idea !

The shifter cam's positio in relationship is controlled by an eccentric screw and locknut where your shift camm return spring is situated below and behind the main clutch bell.

Loosening the locknut and turning the screw either way 1/4 turn would centre the shifter tong where it rotates the shifter drum right above the clutch.

Gimme time will try to post pics to explain.

If you are not in Bangalore or Chennai then dont do porting n all or search the net and do it with specialists in these citys, pay a bomb to them and get a pocket rocket, but be ready for long wait periods and heavy load on your pocket.Even RXC180 is also there.

That should read 1.5 mm.

Zero happens to be next the decimal on the keyboard, hence the typo error!!!

Is it possible to use a Grp C RX135 on road? Or is it asking for trouble?
