1. vacuum leaks at the back side of the carb spigots or other vacuum lines off/broken. Remove the carbs and spigots from the head and clean with acetone/laquer thinner afterward sealing the spigots to the head with gasket maker/silicone rtv.
2. Carb idle and low speed jets may be plugged up and carbs need a correct cleaning.
3. Carbs need rejetting to match the after market mufflers. Take it to a shop with a motorcycle chassis dyno and they will be able to tune the after market pipes.

How to decrease the exhaust sound of Vespa PX150


Hi, Saleh that all depends on your current muffler if it's a stock OEM muffler that is in excellent condition then you would have to seek the advice of a muffler expert to fabricate something for you but if it has rusted holes or has a broken baffle or you have an aftermarket performance muffler installed then a new OEM muffler would quiet down the offending noise..

Need to replace muffler on 2004 buell blast


If it is a stock muffler then buy another stock muffler and put it on - they are ALL the same. Buell never changed the exhaust on the blast at all. If it is aftermarket(vance and hines) than you need to measure the pipe and find something that fits.

Would after market slip on exhaust affect engine compression of zx10r? What is the best after market exhaust slip oni can to use that would have no effect at all on the power of the zx10r? Are there any...


As long as you get a muffler that is comparable to a stock muffler then it will have no effect on the performance. Most aftermarket companies make stock mufflers that would fit your bike though it would likely be cheaper to just replace them with stock kawasaki pipes.
As to replacing them, using an impact wrench will make removal easier and be sure to use a new clamp even if the old one looks good

I have a 2000 Honda VT1100 Sabre Shadow. It's got aftermarket Vance and Hines pipes. It continues to have a backfire when moving up through the gears. I've had the jets (and K&N filter and plugs)...


When you installed the Vance and Hines pipes did you use new gaskets? Popping and backfiring is often caused by leaking copper o-rings in the head to head pipe connection , or head pipe to muffler gasket. Sealing the system will prevent oxygen igniting the unburned fuel in the exhaust pipe. Hopefully , this is all you need to stop the popping.

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.

When at idle it shuts off and while down shifting it backfires


You may be experiencing ethanol fuel , it can lower your idle. Use the idle adjust screw on the carburetors to raise the isle enough it wont kill. If the carbs are dirty use a fuel system cleaner in the tank like Chevron Techron to clean the varnish/gum out of the carbs. Backfiring is caused by air leaks in the exhaust system , usually the copper o-rings in the exhaust port where the pipe plugs into the head. Sometimes a bad gasket between the head pipe and the muffler is the cause of the backfire. When exhaust systems are replaced the gaskets are often reused , when they fail you get air leaks that cause popping and backfiring.

I have a craftsman LT1000 with a B S 20 hp twin motor. Recently it started backfiring after it runs for about 10 minutes. Only after it's warm it backfires. I changed the oil and filter, plugs,fuel filter...


Carb is running a tad rich and the fuel collects in the muffler. My 20 twin has done it since I bought the thing and that was almost 8 years ago.
Cut the engine idle down before you cut the key off and minimize the bang.
Someone else may give a better explanation of the why but it is just annoying and personally after rebuilding the carb and checking the fuel pump on mine it still does it on occasion. Hasn't hurt a thing on in all these years and I actually thing it blows the soot out of the muffler when it does.

The backfiring won't harm anything, it is just annoying. You can reduce the backfiring on deceleration to a minimum - or maybe eliminate it completely - by having the carburetors synchronized.

To be safe, you are probably going to be better off in the long run if you put the arrestor plates back in. Not just from a noise level concern but also because this modification may cause your allready lean-running engine to run even leaner. This can cause driveability problems in cold weather and perhaps a slight reduction in engine life.
