2005 1100 vstar oil leakig out of air box


This happens on any bike when it has been filled with too much oil and has been taken on a long run. There is a breather pipe (for air and oil fumes) between the engine and the air filter box. When there is too much oil in the engine it pushes up the pipe into the air box, then drips out where it can. Check oil level properly, ensure bike is level, not on sidestand, read manual on how to check the oil level. If necessary take some out, the easiest way is to do a normal oil change, or repeatedly syringe oil out of the oil filler hole. Then wipe clean the airbox interior and if the air filter is oily change it.

Oil leaking from air filter


Hi Anonymous, oil leaking from your air cleaner is caused by oil carryover from the engine. For what ever reason the breather system is not seperating enough oil mist and air from the piston downstroke. There are cheap and quick easy fixes and there are more exspensive ones. Start by trying the following:
1. Run your oil level half way between the add and full mark when hot.
2. Run oil breather lines from head into a TEE fitting below carb/induction module then a single line into a mini filter under frame.
3. Purchase Arlen Ness Super Sucker.
4. Replace umbrella valves and realign oil pump
5. Upgrade oil pump and cam plate
Good luck and have nice day.

2000 FLSTC Heritage Softail Classic: 2001 heritage is blowing oil through breather.why?...


All Harleys after the year 1992 will have some engine oil carry over visible in the air cleaner though there is a diffrence between excessive and normal although if you get on your bike and travel down the highway at a constant 80+ MPH you will find that you get more carry over to the air cleaner then you would normally riding at lower speeds and this is simply cause you are running the engine harder and therefore you will see more carry over at the air cleaner. Now to be sure, make sure your bike is sitting on level pavement and in the case of a Softtail model it should also be upright and level pull the dipstick from the oil tank and wipe it clean, reinsert fully into the oil tank and remove it again and look to see if your oil level is roughly halfway between the check marks on the dipstick. If so then yes your oil level is good. I would now remove the air cleaner cover and wash any excess oil out of it and if your running a stock air filter and you have had a oil carry over issue for awhile now, then replace the air filter, reinstall the air cleaner cover and go ride the bike for around 50 miles and by ride the bike I mean go ride it like in town and on the highway without being abusive to it or excessive speeds(70 mph). Then remove your air cleaner cover again after your test ride and look to see if you have any oil carry over in the air cleaner. if so let me know and we can go into further detail.

Fuel starvation most likely caused by plugged fuel filter. Best way to check/fix is to drain gas tank then remove on/off/res petcock assembly. Filter is removed with assembly and can be cleaned with carb cleaner, blown out with compressed air, and re-used. Do not get solvent or carb cleaner on any rubber parts as this will harden them. Re-assemble and start with fresh gas. Oil in breather is normal if not excessive and can be sign of clogged air filter or worn rings. Fix fuel and air filters and re-check. Good luck, Techjoel

Oil pouring from air filter box


No, that doesn't sound good. You must have over filled your oil? Either that, or you have bad rings,sticky valve.

Haryley tranny's do make a lot of noise, a good clean snap is normal. I ride a sporster and oil through the air filter is normal. Try running it a little low on oil it will help and it won't hurt the engine.

Oil in my air filter


Oil in the air filter could mean tht the piston rings are weak thus throwing oil from the breather to the airfilter via the breather pipe.
Some filters do require a little oil like thK & N ones maybe in your bike it was over filled if at all.
You can run the engine with out the air fliter and see if theres smoke coming out of the breather pipe, if it does thn you will have to replace the piston rings or more over rebore the block and replace the piston kit.

Hope this helps !

Oil in my air filter?


This is normal. The air filter is re usable on a lot of two stroke engines and you wash the filter and oil it lightly to help catch dust.
