Re: Pulsar 135 LS starting to get rain sick, in it's 4th year.

Common people nobody want to share their two cents? :P

I'm certain this problem crops up when i ride through water or in rain, buy how can water damage the stator coil?

Is water falling from tank drain hole on the ht coil a problem? as my drain hole pipe went missing after a svc

my spark plugs are new, should i change plug wires and caps etc, all the coils will be checked on monday.

what else in terms of electrics can go bad in my bike? dunno if its related but after heavy rains my neutral indicator was showing on even though i hadn't put the key in my bike.

Re: Pulsar 135 LS starting to get rain sick, in it's 4th year.

Hi man
Sorry to hear that you are suffering from such a problem.
I dont know if stator coil will render the bike unusable.. because basically in keeping the bike in combustion state where fuel is burnt in the cylinder.. only intake -the air filter, carb, jets in the carb, the combustion chamber, the valves play the role... Cdi & spark plug too.. but since u checked ur tank- its doesnt have any water, okay

What i think really is you you should get your mixture checked once ie the air fuel ratio by a good mechanic. Basicaly during rain the moisture in the rains may enter the air filter & it being a sponge air filter...becomes difficult to process air to the carb. So from what i read i think its your carb -that need cleaning, the jets, the air filter is absorbing water from somwre or somhow..if you get this sorted your problem will diassapear for sure

Hello xbhpians

Lately my bike has been behaving rather oddly in the monsoon's, the bike starts spluttering when it rains even a little, or if i take my bike through a puddle etc. the splutter gets worst as i open the throttle more and the engine starts to almost die. Its as if the bike may run on idling jet but will die on accelerating. Now i have emptied my tank one while this was happening and found no water in the tank, the mech says it may be the pet cock thats not allowing the petrol to flow. after the bike engine dies it starts again in first kick or electric start, but as i start riding again the splutter comes in, some times i open the tank lid and start riding eventually the bike runs with lesser splutter.Now i am confused is rains is playing a part or the fuel cock or is it the rains or is it something else. Is vacuum building up in the tank for some reason?? I don't have this problem on days when there are no rains. Any leads to how do i pinpoint the problem?

any help would be appreciated, as this is getting frustrating by the day.

Update : got the petcock changed, removed and cleaned the tank lid,still no good, on event of little rain bike starts spluttering, assuming tank vacuum to be the problem, why does it happen only when it rains and no probs when dry. Where else do i look now to get this sorted. Chkd the air filter, will chk the carb,ht coils sprk plugs and cdi today.

So as it turns out, its nt the vacuum in the tank created by plugged holes, or a petcock or a fuel or air supply prob, but a leaking coil. Noticed today but it was also causing my tachometer to jump erratically. Works going on so will keep u ppl updated incase anyone faces such issues. The symptoms were so generic, wonder how it strts leakin wen it rains, i cud also hear sparking sounds sumtymes near engine cover.

Brooo. . . Cover the fuel tank from top with some plastic cover and see. Also there is bunch of wire packed in some rubber type of thing near headlight assembly . . ( Where headlight assembly connect with other body right below the fuel tank) There are white colors of sockets male female water might got there also. I faced same problem in my pulsar in 2011.

Check intake manifold please, there could be any cracks/cuts.

Re: Pulsar 135 LS starting to get rain sick, in it's 4th year.

Might be totally unrelated, but check to ensure that the battery terminals and wires are proper and there is no moisture/water around there. Also check to make sure there is no cuts on any wires on the bike which might be shorting when it comes in contact with water. Third one is to check for the air intake part whether any blockage or water is affecting air flow into the carb.

Yes i am going to replace it problem or no problem.

Will open the headlight assy and spray the contacts with wd 40.

Will check.i chckd fr parasitic battery drain but there arent any,the groud is good, and the battery contacts are clean and tight with petro jelly on them. Im certain water is affecting the electricals which in turn causes ignition problems, why else would the tacho needle jump like crazy. Also wat wud cause the nuetral light to glow without switching the bike on at all. No key in the hole.

Re: Pulsar 135 LS starting to get rain sick, in it's 4th year.

Check : fuel filter, Carb, Intake mixture (tuning), intake manifold for cracks or seepage as mentioned earlier.

Check : Fuses, electric point, wiring and connectors - rain proof it. (Tacho reading is probably connected with sparking not sure... so problems could be from here)

Hope your ride starts behaving soon.

Re: Pulsar 135 LS starting to get rain sick, in it's 4th year.

Checked the intake manifold, carb,spark plugs,ignition coils,drain hole,tank breather hole,all the hoses,battery,ground connection etc nothing found. And it did not rain hence couldn't test it in conditions when the prob surfaces. Its running like a beast now that there is no rains. Can water in ignition switch or kill switch cause this?

Re: Pulsar 135 LS starting to get rain sick, in it's 4th year.

Damn it rode through a small puddle today and it happened again. The bike was dry, sme water mst b pickd up by the rear tyre, where can water spill cause this

Re: Pulsar 135 LS starting to get rain sick, in it's 4th year.

I think personaly somehow the water is seaping into ur carb or ur intake system for sure... Otherwise there is no reason why itd behave like that

HI,
Sorry to ask you about the query you posted years ago. Did you find the solution for that,coz Im having the same problem for 6 months no one solve it for me not even from the company.

Kindly do reply.
Thanks

Yup turns out, there's a charging capacitor under the riders seat, it's next to the CDI box. It was shorting due to water. Might try sealing the capacitor contacts with silicone.

You may also check for possible shorting or stripped wires near the two ignition coils.

Thanks for the reply. I'll do check on those. Hope it solves the mystery.

I came to this thread while searching for Pulsar 135 statos coil and started reading. I could be there to solve your problem but I was not. Sorry for that

I don't know if you have actually found the problem and rectified it, but for your knowledge (and the same you can spread), I would like to answer.

There is a stator coil inside you engine which gives current output through 5/6 wires through a female coupler. These wires are directly connected to CDI and to RR unit. CDI gets is current from two wire and RR unit gets its current from remaining 3/4 wires.
- WHat is wrong here is that in case of washing/rain, some water gets inside this white plastic coupler and started shorting the ignition coil/CDI wires. It doesn't affect engine in idle because current production in idle is very low and water cause negligible effect but when you twist throttle, rotor inside spins fast, produce more current and then because of water there is good amount of continuous pulse shorts between the wire which results in hindrance to current going to CDI/SPark plug.

- In short - open LHS cover, find this white coupler, unplug it, mouth-blow air 3-4 times, connect it again and start your bike. Done.

Help others in rain too.
