Question about 1986 Honda VF 1000 R

Air filter smell like gas

I pulled the air filter out of the bike last night and it smelled like gas. :shock: any thoughts as to why filter would smell of gas. I called a Honda Dealer the other night and asked them how much to tune carbs. What year they asked? 1983 I replied. We don't work on anything that old :shock: they replied. I called another dealership and they replied. Not a problem!! Bring her in. They said honda and other bike manufacturers have the same rule. Afyer so many years they don't work on them because parts can be hard to find. My view is what difference does it make how old a bike is. If the bike is in good shape and just needs minor work? Carb adj//valves adj etc etc. Honda shop 2 said they don't like getting deep into an antique bike as parts can be hard to find. I say if a customer takes a bike to a shop and it needs parts that the dealer can't find...ok make a list of parts and let the customer find the parts. Then give them to the shop and let's get the bike back on the road. We live in a world wide community. The internet always has parts for old cars and bikes.

It's perfectly normal for an engine with a carb to have an air filter that smells like gasoline. The reason being is because of a concept called "fuel stand off" - in a nutshell, the air that is going through your carbs towards the cylinders gets bounced back towards the air filter when the intake valves close. Since carbs aren't that smart, the air coming back towards the filter picks up even more fuel from the float bowl, and then heads in to your air filter box to say hello.

Might be Normal. My 06 Nighthawk with 1,000 miles, Did the same thing. Smelled like a lawnmower thats been sitting. I use it a couple times a week. What I did while I had the AF out, Was clean the carb with spray cleaner. Weird thing. My bike was idling at about 1800. Afterwards about 1500 rpm.

Going to assume your not FI, so with that being said, smell your oil, if it has a smell of gas then your carbs have flooded and you have gas in your oil. Do not run the bike, change the oil & filter and fix the float's or it will happen again ... ethanol is our worst enemy!

Engine oil appears to be discharging through the air breather. Came on all of the sudden and seems to foul the breather within a short period of time. Rode about 20 miles and stopped within half an hour...


Check your oil level . If it is too high smell the oil to see if it is fouled with gas. If your carb needle sticks the carb may over flow filling the engine. When the engine is too full the breather blows the oil and gas into the air box. Another way to get gas in the oil is if the fuel petcock malfunctions and pours gas into the intake manifold. If the diaphragm of a vacuum petcock gets a hole in it , the engine may flood with gas. The gas flows into motor and past the rings. If you look under the engine in front of the rear wheel you may see a tube with a plug in it. Place a pan under the tube and pull the plug. It is a pollution tube for emptying the crud out of the bottom of the air box. Some Honda's used to fill there engines with gas randomly. If it happened you just changed the oil & air filter, and kept on driving. It just happened for no logical reason. So check your petcock and carbs for problems, change your oil and air filter, and always turn your petcock off when not riding.

Bike kicks over i smell gas wont start


You need to check you spark. Pull the spark plug wires off the spark plugs but leave you old spark plugs in the heads. A Twin Cam has a compression sensor and will not fire the plugs if it does NOT sense any compression. So, don't remove the plugs. Instead, insert a new set of plugs into the wires. Ground the plug against the heads and spin the engine over. Watch for spark at the plugs. If you see the spark, then change the plugs installing the new plugs.

If this does not solve your problems, you need to investigate as to why you're smelling gasoline. Remove the air cleaner cover and the air filter element. Look for fuel leaks to begin with. Then, crank the engine over and see if you see any gasoline coming from places that it shouldn't be coming from. Listen for the way the engine sounds as it turns over. Does it sound right? If it sounds uneven or like it's spinning too fast, you may have a compression problem but this is the least likely of the problems that could be causing your bike to fail to start.

Good luck

Bike starts fine with the choke and will idle without it when warmed up. However, when I twist the throttle the engine dies. I have just had a bunch of work done with an independent shop, including...


hmmm, a few posibilities, might well be split cab diaphragms but overhaul should have spotted that. sounds like either too much gas or not enough, either flooding/gassing up or fuel starvation. could try running it without the aire filter too see what happens. it should run weak so if bike is better then you have too much gas, if bike worse then runnig weak to start with. I have seen this before with one particular cause.... petrol tap was leaking, gas runs past pistons when bike not running, soaks past and into crankcases. as breather recycles vapour back in to air box, when bike warm it's as rich sas hell. take of oil filler cap on engine and have a good sniff. you should smell only oil, if it's a strong smell of petrol, change oil and filter, dump petrol tap or see if new seals available.

SMELL OF GASE


sounds like your bike is running rich. Probably wouldn't hurt to have your carburetors adjusted and synchronized.
