if it is open loop ( O2 sensors) check the sensor condotion, connections etc.

Reload the files onto the Power Commander, insure they are the exact files for your ride, the wrong files can affect operation and gum up the O2 sensors.

hi.generally speaking hydraulic brakes are very simple,the biggest problem is air in the system,here is how i bleed up brakes (same process for front or rear),,remove the resovoir cap(clean around it first so no contaminants get into the fluid),,top up the fluid from a new bottle(fluid that has been exsposed to the air will absorb moisture and this results in a spongy feel at the lever),,pump the lever 3 or 4 times,,,then while holding the lever on,crack(undo)the bolt coming out of the master cylinder(its a banjo type bolt that holds the hydraulic line onto the master cylinder),,you should see air and fluid escpe from around the bolt,repeat this process untill all the air is gone(the master cylinder should now be bled and free of air)now go to your brake caliper locate the bleed nipple and repeat the procedure,so pump the lever a few times untill you feel pressure then crack the bleed nipple,you shouls see air and fluid escaping,remember to retighten the bleed nipple before letting the lever go or you will **** air back into the system,oh and remember to keep the resovoir full when you are doing this ,if you let the fluid level get to low it will **** air back into the system,,another point ,,clean up the brake fluid off all surfaces (especially paint)with warm soapy water straight away as brake fluid is the best paint stripper that i know of,,if you follow the above procedure you should have brakes(unless there is a problem in the caliper)but that is not normally the case,,good luck and hope this helps

SOURCE: High Idle On Start-up.

Most fuel injected motorcycles do start up in a "fast idle" mode. Although I don't know much about fuel injection on Harleys (H-D will not tell you much about it unles you are one of their technicians), I don't think the system is equipped with an engine temp sensor. Since the crank case sensor get it's pulses from pockets cut into the outer edge of the left side flywheel half, the sensor will have oil on it.

SOURCE: 2005 carbie starts but misses and backfires at

Did the kit come with a new needle? It sounds like it's a little lean in the mid-range. I'd pull the slide out and take the needle out of the slide. From the long end of the needle, slide a 3mm flat washer up onto the needle. Use a small dab of grease to hold it on the needle while you put it back in the slide. The small washer should be about 0.020"-0.025" thick. This will RAISE the needle just slightly enriching the mixture just a bit in the mid-range. It will not change your idle setting nor the wide open throttle jetting.

Good Luck

Oil dripping 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

I have a 2008 flhx with samson slip on mufflers.i want to install screaming eagle high flow air cleaner and not sure which fuel mangement system to use.ive looked at terry components terminal velocty,and...

I've heard great things about the Terry components tuner but havnt used one yet. If u plan on doing any motor work or anything in the future I would use the hd super tuner. The power commander is also really nice and there are alot of maps available online for free. If u have a local dealer or shop u like using, see what they prefer to tune with on their dyno, that way if u have an issue with the bike they will be familiar with the component. Good luck!
