Hi ,
Your bikes engine is running too rich !! , you will have to set the air-fuel mixture ratio.
Try to check the air filter it may be too dusty and kinda clogged thus not allowing air to go in.
If all is ok thn you may have to clean the carbs and reset the float in the carbs.

Engine race and new spark plug is rust carbon every 5-10km


1.check your engine oil level. 2.check the silencer whether black smoke or blue smoke? in case black smoke, airfilter is blocked and improper air/fuel screw adjustment in carburetor. in case blue smoke,the oil burns inside the cylinder, check the valve clearance or the cylinder need to reboring or replacement along with piston....

I have A 1988 Virago 1100 With Cobra Mufflers and The Carbs Are Jetted with A cobra I stage Kit And The Fuel Air Mix Screws are new It Cranks And Runs But Black Smoke Is Comming out of the Pipes Whats


Sounds like you need to take it to a shop that kinda knows what they are doing. If they have problems they can call cobra themselves. As a shop the aftermarket companies are usually pretty good about helping out since most of their product is sold or installed in aftermarket shops. With that being said. I would start by dropping the clips up one notch and see how that works. By sliding it up one notch it should run a little leaner . If it's better but doesn't cure the problem then go up one more. If it does clear up the black smoke then there you go. Generally cobra will tell you in the directions what common jets to install. They even have a section for higher elevations as well. If not in the directions they usually do on their website. Hope this helps a little.

My bike is running really rich and keeps fouling out the plugs. Whats the problem with my bike??


Dirty air filter is the most likely cause. Will your bike run leaner with air filter removed? DId you recently move to a different elevation? air fuel ratio needs adjustments in that case. Have you recently installed aftermarket intake or exhaust components? if so the air / fuel ratio adjustment is also required. To check for leaner running with air filter removed, you should buy some new spark plugs so you can see condition of plug correctly on the new plugs. First run the bike at 1/4 throttle for 15 minutes and remove plug and inspect. install new plug and repeat test for 1/2 throttle, 3/4 throttle, and full throttle, replacing the plug prior to each run. The throttle positions can be marked off with white tape and black tick-marks. you will put a white piece of tape on your rotating throttle with a single black tick mark and then you will take a second piece of tape on the stationary part of oyur handle bar and put a mark for 0 and full , then half, 1/4 and 3/4. these marks will help you maintain postion during the tests. The plug conditoin will reveal which fuel circuit you should address for your fouled plugs.

Honda Valkyrie runs rough


Your carburetors have varnished fuel in them and need cleaning. You most likely have clogged slow and fast jets. The fouled plugs pretty much say it all with this regard.

91 kx 250 blows smoke and drips alot of unburnt oil out the pipe


Does it have a stock pipe,carb,any modifications! If its stock,I would put a new ring and piston in it,it seems like your getting a lot of blowby,also make sure your air filter is clean. It would help if you used an iridium spark plug.

Harley Davidson street glide idles low and sometimes dies at stop signs?


Possible cause is a crack in the fuel filter shell which is installed inside the fuel tank. Harley has a recall for affected models. Post your VIN number or go to your local dealer and ask him is there a recall for your bike. All he will need is the VIN number and any recalls will be done under warranty. By the way, not sure of the year of your bike but it may still be under warranty anyway. Other than that there could be a TP sensor fault.

Running rough


fouling plugs and backfiring. Runs much better at high RPM's. I realize that the problem is likley worn needle jets after reading through forums. I am just looking for a little direction on what to do exactly. I haven't messed with carbs much and am concerned with messing something up. I have a Haynes manual, but still am lost.,Hi, I have a 98 M750 that I have had for 8 years and it has done 110,000Klm (68,000 miles) when it had done about 20,000Klm it was doing the same thing as yours fouling plugs and running rough at low speeds, so I took it to a good dyno tuner and he found the bottom end rich and the top enp end lean, resetted the floats and rejetted all good again. So just find a good dyno tuner. Let me know how it is going after the tune up.,,,
