Question about 2013 Harley Davidson Trike Tri Glide Ultra Classic
Have a 2013 tri-glide. Every now and then I loose throttle power as if the cable broke. Shut the bike down and wait 10 mins and start it up have full throttle power again. What is the cause of this? @
For the DIY boater it could be a number of possibilities - fouled plugs, old fuel, improper air fuel mixture or dirt in the carburetor.
Pull the plugs and check the color of the ceramic. Light tan is good. Dark and oily is an indication of misfiring, fouling and too rich oil or improper air mixture. Make a note of which plug came from which cylinder. If they're all about the same color (dark) replace them all. Properly set the electrode gap and install the plugs.
You could try spraying the intake with carb cleaner like "Gum Out"
to clean out the carbs too.
Drain and clean out the sediment bowl of the carb(s) test again.
If cleaning sdoesn't take care of the problem then you need to Reference a Mercury marine manual for initial air screw mixture settings, ie: air screw location and how many turns out are recommended.
Air fuel mix is adjusted by a screw on each carb. No more than a 1/4 to 1/2 turn should be made at a time. Test again.
Also when you store the motor for the season, get some "Gas Stabilizer" for the fuel tank. Mix the recommended amount in a full tank of fuel, run the motor for several minutes. This step will put the stabilized fuel into the carbs for storage.
Hope this helps.

Could be the fuel filter but I'd bet money on the fuel tank vent. Loosen your fuel cap and take a ride. Don't take the cap off, just loosen it a bit. If that cures the problem, buy a new fuel cap.

sounds like the problem is your battery is not charging when you are riding. The most common cause is a faulty regulator / rectifier. Contact a motorcycle wreckers for these parts, or your yamaha dealer.
Easy way to test is, when your bike is running, and the lights start to dim, before the bike shuts down, using a volt meter, test the voltage at the battery terminals, should be about 14V. If faulty rectifier,no charge going in to your battery, then the reading will be low, about only a few volts. If you dont have a volt meter, then any mechanic shop can do this test for you. best to have this done before buying any parts.
