20 Most Recent 2013 Harley Davidson Trike Tri Glide Ultra Classic Questions & Answers


Did you check for a spark? Remove both spark plugs. Put them back into the boot covers and hold them one by one against the cylinder or any clean metal part. Ignition on and turn the engine over. You should get a fat blue spark?

Put your finger in the plug hole, turn the engine over. The compression should blow your finger out.

The plug should be wet with fuel if the carburetor is working.

Engines only need three things to start
Compression
Fuel in the right dose
A spark at the right time, just before top dead centre on the firing stroke of the 4 stroke engine.

Hopefully our Harley Guru and ex dealer Greg Mahin will be along soon with manuals and more advice.

Lots of advice here

I am unfamiliar with your bike model but it isn't a good idea to use a high performance car type charger on a bike, especially a starter charger - usually it isn't wise to use one with a modern car except when desperate, at least the car has a higher capacity battery that can buffer some of the surplus power.

The little trickle type chargers are ok and the low power types aren't too bad but a so-called rapid charger, high output chargers and especially starter-chargers are the enemy of electronics - the open circuit voltage of a starter-charger can be nearly double the nominal vehicle voltage.

It is possible the bike electronics are damaged - I suggest you remove the battery or at least disconnect it, charge and test it and replace it if it doesn't test good, meanwhile read the bike handbook to discover the meaning of the red key light and how to deal with it.

Yes the gauge could be a bit out but bear in mind that a alternator when charging will kick out around 15 v anyway so shouldn't worry too much about it.
