If you do have the list of what and all has been done please post up.

Edit : Don't get me wrong, if your rebuild is over and u still have some engine issues, then what was the rebuild all about, i mean whats the meaning of rebuild here !!! !!

Except chassis everything is new , all cycle parts .

Engine : bearings , seals , con rod , piston rings , all new .
Only thing old is the bore and the piston .
On the piston only the ring locks were worn off which the guys said its no problem .
Rest the piston is fine .

Oil used : Engine oil - castrol 20w50
2T oil - castrol
Using it with oil pump .


Its ok anna , you can tell anything . How can I take u wrong , no need to be formal .
There is a distinction between an automobile engg / a bangy mech and a simple local mechanic here in a town where most people dont have much technical idea . The guy did what he could .

I request you help me out to troubleshoot the problems .

Two problem only there , one being engines biggest enemy :
1. Overheating .
I am actually confused here , a couple of mechanics told me that RX does heat this much . But as I described I feel its over heating more or much more than it should .
I ll repeat once again .
Heat can be felt near the head and more near the fins only after some hundred mts .
After a couple of kms it if you are wearing slippers or some part of your foot is naked , you ll feel the heat literally radiating . I have heard such thing in an SBK .

Well everything was done in front of my eyes from scratch .
So definitely there is no problem in the bottom end .
If there is some problem its with the top end - bore which was also done but there may be some problem , I ll try to show it to some other turner . Or the exhaust which as I said is left to de-carbonize . May be its clogged which is also leading to over heating . Or there may be problem with the timing . The guy has no idea about it . But this is a stock 3rd oversize bike , so do you think there is need to change the timing ? .
Running on oil pump , its working but dont know if its working properly.
May be excess oil can also lead to making lean and ultimately lead to overheating .

2. Noise near the bore area .

I feel its the rings noise , may be clearences not set properly.
I ll re check it , but after that it is not sorted I ll run as it is because then I have run outta reason for the noise .
The mechanic told me that except for standard size , if you rebore an RX it will make some noise ... He previously worked some years with Yamaha and says from his experience this noise will come .
I know its wrong , somewhere some thing I ll have to do myself so need help of you people here .
Please help me out .

Except for these problem , the bike runs absolutely fine and to be true it feels awesome . The acceleration , pickup , ride quality is so good.
Its quite flickable and corners well .

Do you guys think Am I being over possesive ? .
Just that I dont wanna take any chance this time .

Thanks

1) Over heating = running lean = not recommended during runnin.

if you spray some water on ur engine head after 10kmsor so the water shoudn't turn into vapour, it should stay where you have sprayed, i have read this on RDD.

2) Never do any timing changes on stock cdi you will celebrate diwali soon .

3) Yes excess oil also would be the cause, try running premix and see teh difference.

Again u are confusing, did the mech do the rebore or not if its rebored the piston would be next oversize if its 3rd 0.75mm ( 54mm+0.75mm).

Rebore and old piston used is i dont have words to say ..


You are not over possesive you are too lazy, you should have gone to tony in first place no matter how expensive/far from your place/ he is.

Quality never comes cheap, cheap never comes with quality.

This is what i have learnt after being ripped badly by mechs.

Thanks a lot anna . This will help me figure out things nicely.
I meant that the rebore was done previously only.
I was always on 3rd oversize .
Means did not change the top end because I thought It was ok and only changed the rings .
Now I think there is over heating , because water does evaporate after some kms .

I also realized the fact ,
the amount of work the bike has extracted from me I have never done in years I think ....
But sometimes hardwork does not pay ...
for eg you have to go to kashmir and you head towards kanyakumari and say I walked so much but landed in kanyakumari instead of kashmir ...
Just always chose the wrong direction I guess ..
You are right , should have waited for Mr. Tony even if he was busy .

One thing for sure , I am never giving up on this bike so one day it will be him or some other expert ...

Have to learn things in life , sometimes the hard way . And I have learnt the lesson now . I realized the importance of expert hands on the engine .
Cycle parts and chassis any one can do .

Thanks again .

@ shivanshu

Thanks a lot for posting and much more for the moral support .
Brother will posting pics will take a week atleast . The bike looks outta showroom though . Except I chose not to powder coat the engine .
And stickering is not kinda stock .

Saw your legendary jap engine . You really tour on it ? .
It really speaks for the bike . I thought it was very difficult to tour on these bikes . But a person does something if he wants to and your love for your bike is evident , that inspires me a lot .

cheers

• You don't fiddle with the timing if you rebore the engine.
• I think you are just running way too lean. Would explain why the engine revs up nicely.Check the plugs and get it tuned properly. In fact, during running-in, run it a bit rich.
• Dont use too much oil.30ml/Litre is sufficient. Too much oil can also be a problem
• Are you running a catcon or a pipe ?

Sandeep am using an oil pump . So the amount of oil the pump decides .
Whats reving gotta do with lean . I mean could you explain pls how a lean engine revs easily .

No am not using any catcon or a pipe .
Normal stock exhaust which is kinda a bit pressed ( no way too big ) on the cone near the engine side but that I dont think is a reason for overheating it .

Hey brother thanks for your kind words... yeah d stickering is my design and I like it plain....and yes I tour on it and have big plans in my head...and beleive me its as simple to tour on these bikes as u do on others... the only thing is that you need to know your bike...

For your over heating problem... I think you need to find a good mechanic soon bro..till then dont rev the bike too hard..and also always be sure that your oil pump is working all fine as you know without 2T Oil 2-Strokes can cause serious n deadly problems... but since you are now with this bike and seeing your enthu level I am sure you will figure it out.... always remember these bikes needs involvement of the rider and thats how we fall in love with them.... and I am very sure you both will be all fine and touring as well soon.... till then ride safe and take good care (both of You)...cheers

congrats buddy
atlast u did it

If you don't know the flow rate setting of the pump, you can't rely on it to be feeding the right amount of oil. Now, what I think is that you rather stop the pump and stick to premix. i.e add oil manually to the tank.

Pipe = chromed silencer.
Catcon = big fat brown silencer with a chrome heat shield.

Which one are you using ?

^^^ Which company declares what the flow rate is to be? AFAIK, they make the pump flow at the rate its supposed to, for the bike its made for (provided of course its not tinkered with and adjusted correctly). For that matter, the pre-mix ratio is also our guesswork, as bikes makers with autolube don't mention what pre-mix ratio we should be running.

There is only so much you can do with theory mate. Its analogous to the eminent Computer Science professor at college who can give rattle off all the different architectures,software models,methodologies etc right off the top of his mind. Put the same person on the production floor and you will see that knowing it in theory doesn't make you an expert when it comes to implementing it in the real world. Now make what you want of it ...

If you read my post - its clear - it should be clear to "anyone" the first time it is read , as to what I meant - "Don't rely on the autolube to be pumping enough oil, who knows ? the mechanic might have set the flow rate to be really low, or the pump might not be working properly ...etc etc... so just use premix - at least you know how much oil you are adding per litre. The co.recommends 3% ratio so you know its around about 30ml per Litre. Whats the fuss ?

Any person who has ever spent a few mins with the "Auto-lube" on a RX will know what I meant. Either you haven't had a look-see there on your bike, OR ... you haven't had a 2stroke with an autolube that allows you to change the flow rate ... OR ...as is most likely from the vein of your questions, it appears you just love to pick on mundane remarks.


I have read through all your theories in all sections and remain intrigued that you can conjure such complicated ideas out of simple phenomena. Its no substitute for some dirty work.

Just sit on a nice stool on the RHS of your RX. Be ready to get your hands dirty. Now adjust the screw on top of the RHS casing (near the front) and see how the rate at which oil pumped into the carb changes. (You have to open the small tube that goes into the RHS Side and have a look-see there for the oil bubbling out....when you pull that tube out, ensure you cover the inlet to the carb with your finger...and keep it covered till you insert the tube back). Fiddle with it for a while and you will not be worried about things like -

"..........Which company declares what the flow rate is to be? AFAIK, they make the pump flow at the rate its supposed to, for the bike its made for (provided of course its not tinkered with and adjusted correctly).

Cheers.

^^^ Gosh, once again this theory vs. practicals thingy is thrown against me! I'm not inclined to believe this happens because of inability to show logical evidence to refute the theory I'v stated, or even properly understand it. I feel that this debate between theory and practice arises in those who have not really understood either... frankly I fail to see this great dichotomy between the two.

Anyways, you are taking this almost personally, and I tend to refrain from that. We (at least me) are here to explore technicalities, options, etc., and not to take personal digs. And in the process I have no issues if anybody brings up theories/info that completely contradict mine... and you could count on me to do the same! It seems a lot of poeple have issues with this pattern of conduct... but then thats not something I can help.

Now I have clearly mentioned that I am assuming that the pump is adjusted correctly. I do this myself, so its not an issue for me. For those who can't, well, you just have to trust your mechanic. As for the pump not working properly, yes this can be an issue. But then pumps are known to be quite reliable, AFAIK... again assuming that it has been treated as it should be. Lastly, which company recommends 3% The bike maker? The lube maker?? Bike maker will, as far as I can guess, not recommend a pre-mix ratio when the bike comes with an autolube system. So thats out... though only they would know what is best. Lube makers at the most mention only a general one-size-fits-all-engines kinda ratio to give a rough indication of how much to use. Some people swear that 2% is good, some will swear by 4% and some by something in between. Anybody can see that this is guesswork at best! Its fine if you are happy with it... but that doesn't change the fact that it is guesswork.

No idea how you got the idea that I'v never spent some quality time with the cute li'l pumpy on my bike. And yes, it is adjustable!

Believe me, there is no substitute for some heavy duty theory either.

I completely fail to see what anybody will achieve by doing this. Is it even relevant to the discussion? How are you going to determine what the flow rate is by just gawking at the oil bubbling out? Besides, while you are at it, the engine is going to suffer...

I think its pretty obvious that we need to check the actual flow rate of the pump, if we are to know that the pump is doing its job right. I admit I do not know how this can be done. If you do, please enlighten me. Its complicated, because the rate will vary in different conditions and I don't think the manufacturers give us data to compare with. Nor does it seem practical for us to check the flow when the vehicle is actually on the go, etc., etc. So unless we have a way to check this, we can again only guess... rather trust that the thing is pumping at the optimal rate, as intended by its maker.

The new model oil pumps on the rx are detuned to one flow affaik, i have sat scarthed my head on it lost a worthy 8002t for 450 kms. and then came to this conclusion of removing the autoulube, i am a guy who always learn the cons the hard way be it mechs, auto lube or rxz rpm werm, i have been there done these things got screwed badly and learnt it a hard way by losing a nice sum of money in each one of them.

The word premix is there on the 8002T can coz some idiots will use it thinking its as engine oil, motul has never mentioned anywhere that it should not be used via auto lube.

I am not advising here to dissconnect the oil pump, but avoid using expensive oils, it just gets over even before you could bend down.

What does "detuned to one flow mean"?

I have the latest Motul catalogue. The chart states which 2t oils are ment for Pre-mix or injector or both. They do not mention what it is not for, only what it is for is mentioned. So its quite implicit. Motul 510 bottle explicitly states that it can be used both ways. I haven't seen a Motul 800 bottle, so don't know if this is mentioned on the bottle itself; but its clearly mentioned in literature that its for pre-mix. It is mentioned on the Motul site also - "pre-mix lubrication only". Please check it out. Whats more, its for racing and off-roading. No mention of street use!

Yes I take that personally because you are questioning the fundamentals. I am sure you have heard of axioms,postulates and riders ? I think you will make the link. And you prove my point when you ask me about how you can determine flow rate when looking at the oil bubbling out of the tube - that comes from experience...practical knowledge....

The manufacturer of the bike mentions clearly in the manual and also on the fuel lid, the recommended ratio of oil. It is 3% for most of the two strokes...in fact almost all of them. I am not aware if in the late nineties and early 2000's some of them made it 2% as you had once claimed in a discussion a few months ago (you can dig it up to verify for yourself.)

Do you own a RX/RD ? Have you owned one ? Ever had the pump fail ? Engine seized ? These are not mere possibilities. They have a reasonably high probability of happening. So to say that " I will not use premix because i have autolube" is ...well.... what can one say ?

I am not saying it will definitely happen to all oil pumps, but where is the logic in running on autolube alone just to prove that it might not necessarily fail ?

I don't have anything more to add to this. You are most welcome to try and pick holes mate... but I am not going to link the dots for you. Please do post your opinions and theories .... I am not berating you for that, but you do pique me a lot when you pick on mundane remarks. Period.

@OutwardlyManiac

Have you come to any conclusion about your problems ?
