saw an really nice modded rx today....

that guy had made it into a 3 cylinder rx300 using 3 rx engines....

the 3cylinders were placed side by side and he was using 2 rd350 exhausts with sum mods inside them too....2 cylinders going into one exhaust and 1 of them had a seperate xhaust for it.....

at first i thought that its a twin cylinder rx100 and chased that guys for a few kilometers but couldnt quit catch him until a redlight....were he showd me the bike and explained about it....also boasting about its superb pickup

^^^ WTH???? 3 cylinders?? Any pics? Absolutely mind blowing to hear & hopefully what he said is true.

3 cyl's thats something unbelieveable u should have atleast taken some pic's with ur mobile cam my friend next time u see him dont forget ok

Impact of 165 main jet

Message for Psycho98 & update after fixing 165 main jet

One word - 165 main jet has crapped the entire bike

I'll be uploading a short video as its more easier to understand over a video & then explain. Anyway, here's the sequence...



From 0:00 to 0:10 - Staring the bike
From 0:21 to 0:36 - Holding the throttle continuously at one position; this is the place at which the throttle is felt constant; anything opened beyond this is explained after 0:49 & anything less than this is explained from 0:37 to 0:48
From 0:37 to 0:48 - Closing the throttle (rotate hand forward)
From 0:49 to 1:27 - Opening the throttle (rotate hand reverse) with 1:27 at highest point; beyond this the engine shuts off
From 1:27 to end - Random throttling

I don't know what's the issue; when I test rode, first time one spark plug lost its sparking power & I'd to change the plug after which I was able to start. I rode for about 1.5 Kms totally & I could not cross beyond 60 Kmph & 5th gear, after which the sputtering increases & the engine shuts off unless I close the throttle & give random throttling.

Hope the point is conveyed; pls let me know what's going on? At this stage I believe deploying even a bigger jet (more than 180) will help as 165 is supplying lesser air+fuel mixture to the cylinder. Am I right or wrong?

If you remember, advised you to go for 180 mains, as this is not the stock carb and expects more to be thrown out, however, when pony 165 was plonked it could not make a proportion correct. We would need to test with 180 to see if engine settles for good.

I'm in no mood to plonk the 180 mains back for now. Oh!!! I forgot to tell that the vehicle became lot smoother now with the 165 mains. Its much riskier to ride tomorrow with the same condition, so I may take the scooter. I need to find out even bigger jets.

Edit - 180??? But Sri, the stock carb is 180 mains or did you mean anything more than 180?

Options - I guess you have 195/210/230 mains. Correct me if I'm wrong.

Its very hard to convey jetting over phone or net,trial and error is the only way ping me if u need help.

EDIT : Try lower size jets than 165 post plug readings please, if the plug is still fouling u are still rich need to go leaner.

Damn right. i have had atleast 20 of such window shoppers recently for whom i kept the parts, didnt give them to anyone else and they simply vanished! They call you on the phone, discuss
the prices, place order and never call back.

But the second plug didn't foul off!!! If I'm running rich & the plug is fouling, why didn't it occur with the 180 main jets? That's even more richer right? But the old plug lasted for atleast 3.8K Kms.

My gut feeling is, even 180 is right, there's something wrong somewhere else

Most of these guys once they hear about the price, they want to postpone because they cannot save on anything except expense on bike & we guys are just the opposite.

Can you guys believe? I haven't bought a single new cloth for past one year (that includes undergarments ) & have been living & breathing only on Rx.

I need to admit one more fact here; someone in our Rx community said they ride like "uncle" inside the city & have a blast on track. Not sure who it is, but that is 101% a right statement. Now days I'm more scared of someone damaging my ride than me actually falling down. Though I don't ride like "uncle", but staying triple cautious. The pain of watching those scratches & the unavailability of parts are the only nightmares!!!

@Psycho98 - Video uploaded

Update
I somehow feel the culprit is not the jet; after updating here, I'd some time left, so I replaced the 165 with 180 mains & gave a try. But to my surprise the sputtering (same as video) continued & I could barely touch 60 Kmph at 5th gear beyond which the engine shuts off. I get a feeling that too much of air is getting mixed or too little fuel is flowing.

I really went mad & disconnected the air filter; which means, the other end of carb is not connected to the air filter box; but the same sputtering & engine shut offs continued. I know its foolish to try without air filter, but since the test was not even a KM, I gave it a try. Atleast now I'm confirmed that its not the issue with jet or with stock air filter; its got to do with something else

So I tend to believe its something else. This evening...
1. I'm going to clean the entire carbs
2. Check the condition of air screw

At this point, I strongly suspect the airscrew (remember the comet's sputtering & broken main jet?). Is there anything else I need to be looking at in addition to these? Pls advice gurus. Tks.

This is the case most of the times. Enquires keep coming & they never call back, hell even i don't give a damn now. I get lot of enquries locally & they ask me if they can come & see the stuff, i tell them politely please bring cash, else a big "NO" & then they never call up again.

There is a saying in Kannada "Bogola Nayi Kacchod illa", meaning a "Barking dog never bites", vice-versa also true. So there are many who just talk around tons & tons of crap over the phone, but when it comes to purchasing they mew like kittens.

Thats correct Krthik. These days i never call back again as im in no hurry to sell any of my parts. I know what they are worth and the worth will keep on increasing as the spares around dry up.
This im talking about only RX and Suzuki parts. I have not even showcased my RD spares coz i know there are only a selected few in India who would actually be buying them.

Aaah!!! C'mon guys, suggest me something constructively, I'm waiting; no point discussing about window shoppers!!!

Update - No issues with air screw or I don't know if there's one. But the work turned out something different totally.

While fixing the airscew after cleaning, the spring fell of within the clutch cover & damn me!!! I'd to remove the entire cover. Then suddenly I hit upon the idea to change the front sprocket & changed to 15T.

A few days ago, when I complained there's a tuck tuck sound from the sprockets, one of our friend said - its due to duped part; man!!! what a genius & what a fool I'm to have trusted some vaccum headed mechanic!!! The part turned out to be fake one & after changing to the 15T, WOW, what a smooth ride? I've never experienced such a smooth ride before in my Rx.

Anyway, for the sputtering part, the issue remains the same as what I posted in the video. Its getting horrible & feel very irritated to ride on it. I need to take it to a mechanic I guess unless someone throws an exceptional idea. What more should I do with the carb? Should I get a stock carb & ditch the TM28?

Here's the fake part that served me for several years...
