Hi and welcome to FixYa,

Appreciate the direct "Ask Me".

To your concern, it would depend:

  • if you are using stock air filters and airbox, then it would be an air leak. The filter itself could be torn, dislodged, out of position, not seated properly, warped out of form. It could also be the bottom part of the airbox is not fitted snugly to the carbs or the upper portion is not sealing/mating with the lower protion;
  • if you are using aftermarket air filters such as K & N, then you may need to do a bit of rejetting or enrich your air/fuel mixture;
  • if you are using velocity stacks with no filter, then the carbs has be retuned, rejet which may not be enough if the engine is stock.
Good luck and Thank you for using FixYa. Happy Holidays.

Pls be informed that due to my current rank and rating, even a Helpful would be detrimental to my status. Should this solution not address your concern, it would be appreciated if you could just not rate it at all. Cheers.

After riding the bike and cutting it off, sometimes after 20 to 30 minutes, when starting, it will not do any more than idle. If you cut it off and back on it will be fine. It also has gone to an idle...

This is caused by the ECU loosing or seeing an in-correct signal from the throttle position sensor (fly by wire). Remove the plug located on right side of bike mounted on the throttle body pointing towards rear of bike. Removal of air cleaner assy may be required. Spray a good quality switch cleaner in both the socket and plug. Allow to dry completely. Use HD contact grease in plug and socket to prevent this happening again.

There could be a number of things going on here. First check your oil level if it is lower than normal you could have a sumping issue going on here. Next is to pull your air filter off so you can see your injectors, turn the ignition on and off 5 or 6 times to make sure your injectors are not leaking. While you have the air filter off look inside the throttle body with the trottle plate open and see if the IAC pintle is moving in and out when you turn the ignition on and off.This only controls cold ilde. If all is good you will have to reset the TPS.

Since 2008, Touring models have an electronic throttle (Throttle By Wire) instead of traditional cable(s).
Also, you might have a "Parade Mode" on your bike, where the rear cylinder cuts out at high temperatures/low speeds (such as being in a parade).
Pull your DTCs (Diagnostic Trouble Codes) and post here and I'll look them up.

Sporster speedometer keeps cutting out

First thing to check and is usually the problem is the Negative battery terminal on the battery. When they come loose they will start arcing as well and will build up carbon on the battery connection and the connectors hooked to it. If it is loose, check and remove any carbon build up on them (chip, sand, file, grind, etc. etc.).

I have a 2005 softail, after riding for about a half hour, whenever i need to slow down or stop the bike will sputter, cough and die, if i feather the throttle to keep it going it still cuts out and dies...

Hi Kmeyer6595, and the usual suspects are:
1. Idle speed improperly adjusted.
2. Intake manifold air leak.
3. Loose low speed jet.
4. Contaminated or plugged low speed system.
5. Enrichner valve not seated or leaking.
6. Leaking accelerator pump.
Good luck and have nice day.

Btw, I’m available to help over the phone in case u need at

If the bike is fuel injected (FXDI), you need to take it back to the dealer and have them take a look at it. There is no "user adjustable" settings on the bike.

My engine idle has been lowered due to it over revving when i put it back on the rad yesterday/. The garage told me the throttle bodies are knackered and need replacing they quoted £1500, any advice...

hi,i would be mighty surprised to find that the throttle bodies are knackered on such a new bike, the idle is set to low if it cuts out at low speed,i would be taking the bike to a reputable yamaha dealer and have the fuel system remapped before i started tearing throttle bodies apart,this is not expensive and if their is a fault then the dealers diagnostic system will pin point it exactly,these bikes go like stink and are normally very reliable and troube free,hope this helps...cheers

Kelhin 40mm cv carburettor harley 1200 xls

No sweat. Screw the idle mixture screw in until it "bottoms out". Do not tighten or you will damage the screw. Back the idle mixture screw out about three turns. Install carburator and check for proper operation.
When you get the bike running, allow it to warm up and then adjust the mixture for highest smoothest idle. Set idle speed to about 1000 rpm with the throttle stop screw.
