The exhaust gaskets really should have nothing to do with whether your engine will not start. However I assume that by not starting it is turning over smoothly like it should when you try to start, having covered that most motors will not start because no fuel, no spark, or no air not withstanding some major mechanical failure in the valve train or timing or piston, cranks et al..
Trying checking for the obvious first fuel, spark, air flow. then go from there hope this helps

Hi Destiny92782,

Exhaust gaskets wont make your bike not to fire up, the gaskets are there to make the fitting of the exhaust pipes tight and not leak.
You will need to check on your bike the following:-
(1) If gas is in the float chamber or even if you pull out the spark plugs it should be wet with gas after several cranking.
(2) check if theres sparks at the spark plug, remove one of the sparkplugs and ground it thn crank her up and see if theres spark.

How do I go about fixing a reving issue on my bike? It doesnt like to rev past about 10,000 rpms. I was thinking maybe the carbs need to be rejetted. The bike will rev to redline in neutral.

Hi, Ani and the usual suspects are:
1. Severely drained or faulty battery.
2. Faulty regulator/rectifier or high output coil.
3. Faulty power valve, solenoid or installation.
4. Clogged air filter or exhaust.
5. Cracked or incorrect float level.
6. Float needle is not seating.
7. Faulty reed valve.

White smoke is most likely antifreeze. Blown head gasket most likely. Does the exhaust smell like antifreeze?

Hello, The nighthawk 750 1993, is backfiring even after I chaged the jets, I when from 35 jets to 38 size jets and main when from 112 to 122 size jets, I put on 4 to 1 pipes and individual air filters, ...

Backfiring is caused by unburned fuel in the exhaust. In an exhaust replacement air leaking past the exhaust gaskets in the head igniting the unburned fuel, will often be the cause of the popping. Be sure the exhaust gaskets are sealing. By removing the vacuum on the intake side of the carburetors you have altered the way the vacuum pistons rise and fall. You may have to rejet several times to get the mixture right (just to get the machine to run). The vacuum at the intake is very critical to the correct operation of the vacuum carburetors on the motorcycle. Consider putting the air box back in and using a K&N style air filter . This may be the best solution to get the machine to work properly with the new exhaust and current jetting.

My 1999 Honda shadow backfires on deceleration after steady throttle what could cause this? I have tuned it and cleaned the carb but it still does it.

The most common reason for backfiring is lack of back pressure from changing the exhaust. To compensate for the flat spot you get you put in a jet kit. This leaves the possibility of more unburned gas getting into the exhaust. Honda uses Kei Hin carbs with a fuel shut off diaphragm to help limit this condition (backfiring) by turning off the fuel to the carbs during deceleration. Even stock exhaust can pop or backfire. Typically it is caused by air getting into the exhaust either past the copper o-ring gaskets in the head or leaking muffler connections from the head pipes to the mufflers. Try replacing all the exhaust gaskets and you should minimize this condition.

Is popping or backfire normal?

Two things can cause popping or backfiring on deceleration. The most common is air leaking into the exhaust through the exhaust pipe copper o-ring gaskets. This typically happens when the exhaust is replaced without removing the old ones (doubled up) or simply reusing the old gaskets and they don't seal. The other thing that can cause popping is bad air cut diaphragms on the carburetors. If they are old and sticky or have holes in them they don't properly shut off the gas on deceleration causing the backfire.

But it will affect how well it idles and reduce your torque due to a lack of back pressure.

I rebuilt my motor on my 2002 gsxr 750 over the winter last saturday i took it out and ran fine let it sit over night and in morning wouldnt stay running and back firing and shooting flame out exhaust

Most likely cause is a fouled spark plug. Engines fresh out of overhaul often have this happen as engine oil gets past piston rings that haven't seated in yet.

Remove the spark plugs, clean or replace them. Also check for cracked, damaged, or dirty spark plug caps. This can also cause misfiring and flames shooting from the exhaust.
