Re: [UT]: Tuning your Motorcycle Carburettor.

Rubber parts do tend to get hard and crack as the time passes by, sometimes water can accumulate in that channel near orfice and that part can get rusted, i hope that hadn't happened to your bike.

No no my bike tank can never get rusted
The bike tank got a dent once, I stripped the entire tank of paint... used a coat of red anti rust, then brown antirust, then filler, then primer, then 2 coats of paint....
After that, I emptied my tank let it dry and poured in a liquid called silicone antirust tank seals. It seals your tank from the inside. It is told to put 100ml and shake the tank around amd pour out the excess, I put in 500 ml and shook the tank in broad sunlight after the tank was already hot.... and poured out the excess. My tank is safe from rust as of now:P

Re: [UT]: Tuning your Motorcycle Carburettor.

Tank was filled with water ! how did this happened, thoroughly clean your tank.

The pulsar lock on the tank has a rubber seal that prevents air and water from entering the tank. It has a channel around the orifice to lead the water through a serious of pipes and holes in the tank away from the petrol side area. Note this rubber is prone to hardening and cracking and water and dust clogs the channel and it overflows with water during rains and washing ...then water enters the tank.
Unfortunately the pulsar tank rubber is non replaceable and you need to change the entire lock set that makes you carry an extra key around:banghead:

Re: [UT]: Tuning your Motorcycle Carburettor.

There might be some water or rust or some other kind of foreign substance in the tank or fuel tap. This creates sludge like substance in carbs. Check for it.

Re: [UT]: Tuning your Motorcycle Carburettor.

I need to clean my pulsar carb.
What do you suggest?
Dismantling it completely or judt using carb cleaning spray from thr air filter place?
divyansh....

Use carb spray in the air jets. Open and clean the bowl, main jet and pilot jet. Spray carb cleaner in to the main and pilot jet slots. That should be enough.

Be careful not to catch the carb spray in the eyes. Use some protective eye gear.

Re: [UT]: Tuning your Motorcycle Carburettor.

There could be many reasons for erratic ideling change
1) kaput carb (stuck or dragging flat needle
2) adulterated fuel
3) dirt in carb
4) water in tank
5) leak in carb hoses that connects to engine and to air filter box
6) air filter issue
7) throattle cabel issue
8) tps issue
9) spark plug is dirty or gap is not perfect
10) spark plug cap or wire issue
11) cdi issue(unlikely)
Check all one by one.
