2005 v-twin fouled plugs

I have a 2005 dyna v-twin with less than 4,000 miles on it. Bought it used last Summer and it seemed to burn oil. this summer I noticed it ran rough and found the plugs to be carboned up. also some oil on the breather tubes that run from the air filter back to the motor. also, some smoke out the exhaust when I first start it. any ideas where to look ?

Fouling can be serious..... or not ....can just be the enricher on to long or worn/bad piston rings. Burning oil and smoking would also indicate bad rings. Could also just be bad plugs. Make sure you got the right ones in there. For $ 4.00 go get new ones at the dealer. Do a compression test - If its OK (over 90 and both within 5 lbs) .... its not the rings. Make sure you have the right amount of oil, and (believe it or not) a weak battery can cause the problems u describe, so check that out as well.

good luck.....let me know how it goes, OK ?

1972 shovelhead engine needs spark plugs and oil!


I have a 75 FLH and I use the Bosch Platinum WR8DP if you have the long plug if you have the short one it is W8AP, they are an exelent plug. As for the oil I use Rev-Tech grade 60 but you should stick with one kind of oil and for a FLH it is 4 qts.

Oil Pressure


Very common on h-d big twins for the last 75 years or so. These bikes have a dry sump oil system which means you have 2 oil pumps, feed and scavenge. The feed pump is very puny compaired to the scavenge, so at idle (especially when hot) it carries only a couple of pounds of pressure and that is all you need. The scavenge pump has a much greater capacity because if it can't keep up the crancase will start filling up and the crank will start slogging through the oil, killing performance. These bikes are equipped with hydraulic valve lifters which will start clanking loudly if you have a real oil pressure problem. Enjoy your ride and don't sweat it.

Harley davidson how to change tensioners


If you have chain Tensioners then you have a Twin cam. This is NOT a job for an amature. Its necessary to take out Push rods which means remove heads or cut your pushrods and reinstall adjustables. You need to take out your cam plate,re align oil pump..Its not a simple job for a novice. If you have noise they have already exploded or are about to. Do not ride your bike..those plastic pieces can get sucked into the oil pump and do major damage. I told that to a customer that was going on a trip he did not heed warning. He got 75 miles they exploded and he bought a new motor.

98 fatboy engine noise.


Harley's do run hot, anywhere from 220 to 240 normally, and a little hotter this time of year. I suggest running a straight weight oil, and a little heavier weight in the summer. I use Valvoline VR-1 30 weight most of the year, and 50 or 60 weight in the hot summer, and I use Lucas 20w50 primary/trans for the primary and tranny. I don't bother with the extremely high prices of the HD oils. For the whining noise, you need to determine which side of the engine it's coming from. Whining will almost always be in the bottom end. There's nothing in the top end that should whine, and if there is whining from the top, it's usually an air leak around the carb. Start by checking the fluid levels in the tranny, and primary. These are the two most common areas to pick up a whining noise. If it's coming from the left, it's going to be in the primary, and usually this is caused by low fluid levels. From the right, it's going to be either the tranny, low fluid, or the oil pump. The oil pump is a gear type system. If you're running a light weight oil, say a 10w40 or HD 20w50, when the engine heats up and the oil thins, it can cause the oil pump gears to whine a bit, especially in the summer heat. So, check the fluid levels, if they check good, then change the oil, since the summer is coming to an end, go with a straight 30 weight. This should clear up the whining noise. If it doesn't, get back to me with the exact location the noise is coming from, and we'll go to the next level of diagnosing the whine, but I believe that this will cure it.

04 1200 Sportster - backfires - cuts out - fouls plugs


Turns out the crank sensor needed to be replaced again (second time in 8 weeks or so!). In the last week Harley has sent out a "improved" crank sensor that does not have the issues of the original. Therefore if you replace it once you shouldn't have to do it again and again. Bike runs great now. We will see - though - my local service manager promises it will stay that way.
