This is Suzuki standard for a Pointy, sure someone will be along soon to say if Curvy is the same or not. Start at the standard air gap then see how it feels from there.

It is a bit too lean on the idle jet I expect or there is air getting into the inlet manifold.

there should be a oil pressure sending unit close to the filter, install a manual guage to check the actual pressure, and chack the filter mouting seal surface with a flat edge it may be warped

located on bottom side of gas tank. should be inline with filter usually left side location

There should be a glass view hole/ window on the left side, opposite the mufflers.
On my 99 V Star, that's where it is.

BAD BATTERY CABLES NOT GROUNDED BAD CONNECTION

You need 3 things for an engine to run; spark, fuel and compression. How is the compression? Is the spark plug new? If the plug is old, it could give a nice spark when you check it but have no spark under compression. Make sure the fuel you're using is fresh. If you give it a small shot of starting fluid and it fires up, your fuel delivery is suspect. In that case, you will need to remove the carb an THOROUGHLY clean it paying close attention to jets and passages. I always give people this warning: when cleaning jets and passages, NEVER use steel instruments. Use wood, copper wire or other materials that are softer than the material you're working on or you run the risk of ruining jets or even the entire carburetor.

check the clutch cable if its working... dismantle the body engine cover where the edge is connected,check if it is working...

Improper timings makes backfire check the timings.

Hi, use your key to open the side panel. You have to unscrew both battery posts in place, then slide the battery out. Don't loose the nuts that the battery screws screw into. Once the battery is charged, you need to put the nuts in place inside the terminals and carefully slide the battery in without disturbing the nuts. Then the screws will go into the nuts for tightening. Always loosen the negative cable first and replace it last to minimize the chance of shorting the positive to ground when attaching the positive cable. Please let me know if you have more questions. I have one of these and I have the manual for it.

Hi and welcome to FixYa!

Yes it may but as a first course of action I strongly suggest that you replace the fuel filter. It can be clogged causing fuel supply irregularities. If it still doesn't help then replace the fuel pump and you'll be good.

Hope this helps and thank you for using FixYa! Have a good one!

r u gitten gas from the tank fawcett? is pump hooked up rite and producing pressure--carb or injectors may need ajustin--buy a clymer manual

First the i would do is clean the carb.

Hello,

Thanks for using FixYa.

What you are experiencing right now is engine backfiring.

1. Use a higher-grade fuel for a while to help clean your fuel tank. You may have ended up with a tank of dirty gas that's causing some problems with your fuel injection.

2. Buy a can of fuel-injection cleaner that goes into your gas tank. This will clean out debris and dirt from the tank that's getting into your fuel line. Check with your motorcycle owner's manual or the manufacturer's recommendations to make sure this is safe for your particular motorcycle.

3. Check to see if the jets are clogged with debris or thick "gunk" that's causing your motorcycle to backfire. This will also cause problems with the fuel efficiently getting through the engine.

4. Take a close look to see if you have a dirty carburetor. The fuel will not be able to run efficiently through the engine with a dirty carburetor.

5. Visit your favorite motorcycle mechanic for an evaluation of the backfiring situation. Your motorcycle may need a complete engine cleaning to solve the backfiring problem.

I hope this helps. Thanks and good day.

What do you mean by "Midway"? How old is this motorbike? What exactly did you do to clean the carburettor? Is it a new spark plug and a new, clean air filter? Did you empty the fuel tank to remove the fuel tap to clean the filter on the inside of the tap? Is it doing anything else? Things like - is it hard to start, has heavier exhaust smoke or it has a rough and uneven idle.

Behind the radiator on the left side. It is the device with cooling fins, even though the electronic parts are embedded in rubber paste.The location isn't ideal and sudden defects leave people stranded so what people do is relocate the regulator/rectifier to a cooler place. Perhaps to the air inlet, under the air filter. Follow the three, mostly, yellow cables that originate from the stator when you don't find it behind the radiator.

A broken timing chain is the most likely cause, the piston is hitting an open valve, or you have a dropped valve or a stuck valve. Another possibility is something jamming behind behind the side covers.The key would be how you discovered this? Driving along at 105 and the engine stopped, or ???https://www.google.com/search?q=2009+suzuki+boulevard+timing+chain+or+timing+belt....
