Need advice to get my Gixxer running smooth after 1 year in the garage.
I did something very stupid. I filled up my Suzuki Gixxers petrol tank before the first lock down began, more than a year ago, and I barely rode her since. I started her a few times, and covered a few kilometers once in a while. She was running a little rough, but I put that down to disuse, and the petrol in the tank being old. She was making a put-put sound like an Enfield, whilst before she used to purr like a kitten.
I've been very busy over the last 2 1/2 years, and have barely ridden my bike. Even before the lockdown, her tank contained some old petrol, which the service center mechanic told me was the reason for the change in exhaust sound. I didn't drain the old petrol, instead I topped it up reasoning that diluting it would make the problem disappear.
Fast forward 2 years - my bikes battery went dead, and kick starting had no effect. I called a mechanic to service the bike and charge the battery. He informed me that due to the petrol turning rancid, the bikes carburetor had jammed. He put it in paint thinner for a couple of days, and the bike started working.
Initially she ran fairly smooth, and the put-put noise was much reduced.
But then she began stopping while running. I turned the carburetor screw to raise the idle rpm, and that helped for a bit, but soon she began stopping the moment I eased up on the throttle.
I took her to the service center today, where we noticed that there was black smoke coming from the exhaust at lower rpms, but cleared up when we raised the throttle. (The bike jerks a lot at low RPM's, but is pretty smooth at anything above 4000 revs.) The mechanic tried a different spark plug (the tip of ours was black), but that didn't help. An older mechanic at the service center, who didn't look too trustworthy, had looked at the bikes black smoke and told me that the engine head needed to be removed and serviced. The younger guy concurred after trying the spare spark plug.
The mechanic who'd serviced my bike and charged her battery had told me that the carburetor was jammed, and even though he'd cleaned it, it was still rough, and would get better with use.
I'm pretty clueless as to what the problem could be and I'd appreciate some help in getting my girl running smooth again.
