Re: Hero Impulse ownership experience

Wow thank you so much for the info. I have less technical knowledge. The mech did check the diaphragm and said it might be the problem. Even they felt the same, the initial is good to 50-60 and when it reaches 65 it's dead. As of now, got the carb and air filter cleaned. more smoother riding now. Will test it soon. If again the problem persist, I might have to do what the mech says.

Re: Hero Impulse ownership experience

Knew it. Had to be the carb. Always is. Carb definitely would be the culprit but I doubt its up for a replacement. Mechanics often tend to evade the situation plonking in a whole new carb. I had several problems with my carb too eventually rectified it all and still on stock with 45000+kms on the ODO with a foam air filter on. I sourced a 1000+kms run carb for half the price as a spare. But the stock hasn't given up yet. Slide needle broke a couple of times. Diaphragm slide itself suffering from scoring a lot tend to get stuck a lot which was emory rubbed smooth and installed back to run quite a long and got changed to a new one eventually after it gathered a lot of play after frequent rubbing and its running fine still. But still on the stock carb which I doubt gets replaced a hat often.

These CV diaphragm carbs are prone to lot of problems and thus I prefer them after the old wire operated slide carbs. Check your diaphragm slide and give everything a closer look. Consult a good mechanic or a couple of more. They might come up with other results.

Coming to a carb change you can plonk lots of others without harming your engine depending on what you ask for. I have friends running n BS29 Mikuni even 33Ucal and other carbs too. I think to go down to VM26 carb for now.

Re: Hero Impulse ownership experience

Thanks man. What if the problem repeats? What then?

Re: Hero Impulse ownership experience

go for stock one

the other one can damage your engine

Re: Hero Impulse ownership experience

Guys as per the mechanic it seems it's a problem with the carburettor. So he suggested to change it. I have two options either keep it stock and see if the performance increases or put 200ns carburettor and filter for better performance but worried if there will be a big drop in mileage or reliability of the engine.

Re: Hero Impulse ownership experience

The other day faced a strange issue with the bike while out on highway, bike was smooth at below 60Kmph and above 80Kmph, but was kind of jerking around 75Kmph as if the fuel was getting over and the bike will come to a halt right in between the highway. To make matters worse I had done servicing just a day before the journey so was suprised at such problem...

Re: Hero Impulse ownership experience

I have no idea. It's doesn't go more than 60-70 even when milking it.

Re: Hero Impulse ownership experience

Re: Hero Impulse ownership experience

Hello friends, I am looking for a 16T front sprocket, I am not able to get it. Can anyone help me with the address and contact number of the shop from where I can source it?

Re: Hero impulse missing trouble

Tru carburettor of pulsar 180 or apache 180 u will need mikuni bs29 carb. Ns carb is too big, and it's nothing to with air filter. Like jets works for petrol intake there are jets for air intake too in carb. Source the bs 29 carb, and do one thing at a time. Or i suggest you to put stock piston and cylinder of impulse. You can see many example here on xbhp which failed at the end.

Re: Hero impulse missing trouble

Yep. Given his current situation its not worth spending another penny on this machine, forget K&N filter, which eventually will f@ck the engine more than ever. Just wanted to help him save some more agony.

Regards.
