I willtry to simplify it as much as possible.

Lets assume everything else is in perfect order.
Gently tighten the air acrew clockwise till it seats lightly. DO NOT overtighten.

Before doing this, Raise the engine RPMs so that the engine doesnt stall when the airscrew is fully inside.

Now turn the airscrew anticlock wise slowly by 1/4 turns till you feel the engine RPMs rise as you come out.

This should be at about 1-1/2 turns from fully seated. This is where you stop. Any further turns will make the RPMs fall again.

Readjust the idle speed by adjusting the idle screw. [ As it does not have a RPM meter you need to do it by listening to the engine sound] .

thank you so much sir...thats a really amazing collection of yamaha's you have there,i'm gonna get to the card right away!!!!

I strongly suggest you get a help of a experienced mech for cleaning and tuning the carb. If you tune it too lean, you may end up damaging cylinder/piston. Not trying to scare you but I feel its better to not take chances with RXs, spares of which are scarce.

maybe on the 1st after i get my pocket money i'l take it to a tuner, for now i think i'l just admire her in the parking dont want anything at all to happen to her.

I think what u mean by "time to decelerate" is the time it takes for the bike to slow down after u close the throttle (let the accelerator grip spring shut) .... This is normal for a 2-stroke.


A two stroke has very little in terms of engine braking as compared to a 4-stroke as there is a power stroke every revolution .... Get used to it.

The thing that u need to learn is how and where to refill the 2T oil in the tank .... and the difference between 2T oil and Gearbox oil

Have seen many a bike ruined by the lack of that knowledge.

Welcome to the world of blazing blue smoke!!!

Ya..I remember telling you Alok about that...Pheww....I've been taken for various jolly rides most of the times when the owners swear on what they say...

Let me try & get a Job & shift my family Karthik....Bangy..two Strokes...Wow...! What a life to live....!

Must be extra careful now....!

First of all congrtas on the bike...! Have you got it for a life time or just for a small time? If it's option no.1, u've been one of the lucky rascals around As Alok & Nitesh Sir said, two strokes have very less engine braking when compared to the 4's & the feel is totally different when shifting from a 4s. As for the carb, pls. get a good carb cleaner like "Cyclo Carb Cleaner" or anything which works & spray it on the dismantled carb, make sure it is clean up to the emulsion tube & put it back together. Pls. avoid spraying on the rubber gasket parts, which if weak will give you a carb that leaks added to the non availability of spares will make you go nuts. If getting the carb out is a problem you can follow what our fellow contributing member Bigbore aka Arun suggested me that worked, open the rubber manifold that attached to the air filter, now start the engine open the throttle slightly & spray the carb cleaner into the carb intake...Make sure you don't over do it, just gentle enough to clean the residue. Pls. make sure you carry this out in a clean environmental space as you don't want more dust to clog into the jets. Pls. follow the seniors advice as they know much better than i do...!

A quick question Nitesh sir, my Air screw setting is little more than 1.5 turns, the bike runs pretty fine. Is that okay??

Just try getting your hands dirty & start learning the basics like carb cleaning, tuning, oil pump adjustments, spark plug cleaning, Spark plug gap measurement, chain adjustment & so...You never know all this will come very handy when you're left nowhere in the middle of a highway alone...!

Btw. I would say you don't need an RPM meter at all for tuning & there was none during the early days for the same. People get used to the sound & graduate it from there...Don't worry, you shall get used to it soon..!

Pls. don't adjust Airscrew from the current position. Close it to the carb on clockwise fully & then open it out to 1.2-1.5 turns as required.


@ Revhard, good point what Nitin has pointed out. One way to check to see if you're running way too lean without removing the spark plug is by seeing how much heat the head generates. Simple, just after a ride splash some 2-3 drops of water on the head and see how it evaporates. If instantly vanishes, you're running too lean & u'll get into trouble. It should vapour off gradually...! Another place to test the same is the exhaust manifold.

+100...!

I dont think getting a job in B'lore is that tough.



LOL........ Btw Ram i wanted to ask, which bike were you riding before this 135? And do you still have any other bikes?

Media Industry is a little harder than the others Karthik...!
Ok, here comes the most embarrassing things.... I was riding a P-220 FI & P-200 before. Gave the latter one to my cousin & sold the FI for the current love affair with the Rx. My daily commuter is more or less the 135 backed with a highly guarded security both in home as well as office complex. My other humble ones are Super Splendor, Hero EZ ( 2 Stroke Scootrette 80cc), HH Plesure (Wifey) & a Dio on the way soon which will hit my 135 in my bed room & for week end rides...

Hero EZ, never heard of it man. Had seen Hero Winner, but not this one.

Can you post some realistic top speed figures of P200 & P220.

And please do comment on that Shougun HIgh speed Problem thread if you like.

Thanks.

Ok, it is the downsized wheel version of the Winner... Here's a small pic that i found in the net..Mine is a grey color one, will post the pics sometime...

With regarding the Top Speed figures of 220 & 200, I guess the realistic would be 115-120 for the 220 & something like 105-110 for the 200. But i must also admit that the 220 had oodles of torque that the 200 missed big time and also the FI helped me a lot in touring, basically not giving me the headache of the AFR problems...!

Thanks for the info ram. May i ask if you are aware of the coimbatore drag results held recently?

Yes its okay. It would matter only if you are more than 2 turns out.

Sorry Karthik, Couldn't make it due to personal commitments..not sure about the results too..!

Thank you sir..!

Thats is how one never gets a chance to learn.

Doc, Nitin was just asking him to keep the consequences in mind.
