I am using ELF moto gold from a long time.

nano-try motul or gulf,id prefer the latter.

I can vouch on gulf, I have tried both motul & gulf & I prefer Gulf over Motul

Same here...I am using Gulf Pride 4T plus 20W40 in my ZMA with good result...after 800 Kms the oil looks new in color and viscosity....

i till date have trusted the TVS true4(from the time it was launched)... it lasts very long... almost upto 5000kms!!! but ya with some gear downshifting probs... will have to try gylf 4t...

You can also try any JASO MA2 spec 20 W 50 Mineral oil...

Guys, there's a strange situation that i am in.

The bike feels very loose, it feels like its missing some sparks, and also feels very wobbly.

I did check the chain tension, as well as the bearings they are all perfect.

all this suddenly happened, when i was riding and it started raining.
the bike turned off, as the spark plug cap might have seeped water in it (this is a very very common problem that i face during first rains).
I parked my bike (after dragging it for some time) at my friend's building who lived nearby, and took a train home.

The next day i went back there, i removed the cap, let it dry off and put it back again, all was working fine.

Now when i was riding it, it never felt like before, it feels very strange.

I assumed that maybe the alternator (which is exposed) may not be working as its turned wet, but on checking with a multimeter, i found that its working perfectly.

I also thought that since my sparking is through the battery, it may be a battery issue, but even that's fine.

i removed the plug wire, and checked, its giving great amount of spark, almost an inch long.

Its a very strange thing, at times it doesn't idle i.e it turns off if the throttle is not held.
The other times it feels as the bike is running terribly rich.
Sometimes it idles as good as normal.
but once ridden, it pulls normal, shoots off well like before, but still there's something terribly wrong.

Do you guys have any idea ??

It feels that the bike will break apart, and also feels that the response suddenly becomes sluggish, and suddenly becomes as good as it was.
Feels extremely unreliable.

I can't even explain properly.

Check for water in petrol. Drain the carb and see.

Try and describe it a bit more technically.Are you sure the engine isn't loosing compression?Because engine always feels 'loose' when compression is leaking.

No, its not a compression issue, kick backs are still massive, so that's not a problem.

I really can't describe it in words, its just that the bike feels very unreliable, it seems its difficult for it to keep running.
Gives me a scary feeling if i ride above 40, as i think it will cease.

With all that i know so far, i can only think of that the bike is missing some sparks, i tried holding the starter for a long time to notice the spark readings after 5-6 crank rotations, and its not missing any.

I can't idle it low, i need to keep the throttle held to keep it running, at least till 2.5k.

but even after all these issues, when i go for a run, it sometimes suddenly feels normal.
if i de-accelerate, it behaves as if its breaking and trying to stop even if i am riding at 4th gear.

that's all i can say so far, i haven't started it yet.

@ abhi

I tried that too, i drained some of the fuel from the carb.
But the thing is, even after riding it for some 20 kms, it still suddenly feels strange.

I guess you did not analyze the drained fuel for water. Its either water or a loose connection in the ignition cable/plug cap. Also, is the ignition coil properly grounded? Check for rust at the bolt.

@Nano :- I think you need to check the carb diaphram, I guess it is punctured, I too faced a similar issue, the engine would never idle properly and it kept on going up and down. Just give it a try.

The bolt is new, and the idi is well grounded too.
Now the funny thing is, all this happened suddenly when i was riding and it rained.

until now i never had a problem of water entering the fuel tank ever in rains, even if my bike is parked outside the college beneath open air and its raining for hours, it never happened that the water entered the tank.

In this case, it hardly rained for 2-3 mins until i was completely drenched and then it just shut off.



idling is not a problem, idling is at it should be, but the bike turns off.
I cannot idle at low rpms, the idling isn't jumping around.
Either ways i have a brand new carb, run hardly for 3000 kms, and unopened yet.

@ all

Its really very strange, its unlike every other problem i faced so far, my mech has his wedding so is out of town.
It rains almost everyday, so i am scared to take my bike for a ride.
I know its not an electrical issue, its not water in the fuel tank either.

Still tell me abhi, should i drain some water in the fuel tank too ?
or keep draining the carb ?
Sparking is also great.

What's that little something that i should try to get atleast somewhere close to a problem ?

Water being heavier than petrol settles down at the bottom of the float bowl. So drain that a little a see if water comes out. You will identify the liquid as water if it does not evaporate quickly in your hand.

Check whether there's any air leaking via intake manifold.That is, make sure the carb is sitting snugly in the intake manifold.
Your carb is new,so it's unlikely that it would have any issues.(once water in fuel tank is ruled out)

So that means it's either electrical or mechanical in nature.Very unlikely that it has to do with the TCI,so check the ignition coil.
