If something flashes, then it wont be a problem with the flasher unit.
There are two types of flasher unit; electro-mechanical, that are a sort of relay that switches itself 'off' when it's switched on, to make the output 'flash'. Flash rate is set by the weight of springs pulling the contacts back and forth, and the 'load' on the relay by way of the bulb-wattage. Other is a 'solid-state' or electronic flasher; uses transistors and a chrystal like a digital watch to do the same thing; but spared springs and things, is not load dependent, flash rate is fixed by the chrystal, so is constant.
In an indy circuit, you have two indicators bulbs taking power from the one flasher. If one bulb blows, the current draw throgh the flasher is halved, so if you have an electro-mech flasher, it will tend to flash twice as fast....
is there a happening anywhere yet?
Sysmptoms described suggest you have an electro-mech flasher unit, and its sort of doing what an electro-mech flasher unit is expected to do.
The bulb you are convinced isn't blown.... because you looked at it?!?!? Might be.. might not be... TEST IT! Get a bit of wire and connect it direct to the battery. Or use a multi-meter on continuity.... 'ohms' setting, to see if electric passes through the fillement... you cant always 'see' if a filiment, inside a bulb is broken or not.
As described, it 'sounds' like a dodgy connection or earth...... new bulbs, clean contacts in the holder; check the wires, check the earths, clean earth points on the frame....
See what happens.
Electric is not all that mysteriouse, it doesn't do 'random', it just follows wires.... that's what you got to do to fix it... logically... not with random, not with guess-work, and NOT with even more random effin You-Tube vids!!! ____________________ My Webby'Tef's-tQ, loads of stuff about my bikes, my Land-Rovers, and the stuff I do with them!

Regs require indies to flash between fixed rates, I think its once a second or 1Hz.
Ways you could make that happen are myriad, but the single flasher unit is by far the most usual....
Clever electrickery means you can actually buy 'component' LED's that do flash without a separate flasher unit.... I have some in the theater lights on my stairs!?!? They change colour too! They're actually a composite device, though, an LED is a Light Emitting Diode... the flashing ones, have control Chrystal and transistor etched on the same substrate as the diode, hence a compound 'component'.
Problem with them as far as indicators are concerned though is that C&U and MOT regs demand that indicators not only flash at set rate, but also that 'all' indicator lamps flash in unison; if you have effectively separate flasher units for individual lamps, then its much harder to ensure they do flash together, and just a small difference in timing of one flasher-controller compared to another can get add up to a big out of sync... use single flasher, no problem, all are synced to the source signal.

There HAS to be 'something' making indies flash, and if you have bulbs in the back, then cant be using compound-LED's, there MUST be a flasher unit somewhere.

Rather nebulouse and over-used term 'custom'.... especially when applied to a stock-catalogue over the counter motorcycle 'style', which ISN'T a 'custom' its a standard catalogue model!
Off the peg, or after-market lamps and the like, are likewise probably not really 'custom'.. they are just not 'standard' to that catalogue-standard motorcycle...
'Custom' strictly means bespoke built to 'Customer' specifications, not 'standard' catalogue ones.....
I have made 'custom' indicators for various bikes, to my own specifications, using component LED's or bulbs; lenses and holders, and brackets etc, and then making my own 'custom' wiring to make them work... they were most decidedly not off the peg after-market 'alternative' standard lamps.... but how far do you go before a standard-catalogue motorcycle can be properly described as a 'custom'?
Knowing blokes that have scratch built frames around a highly modified engine, Some-one chucking some off-the-shelf e-bay-tat or waving a rattle can over at an otherwise brochure 'standard' motorcycle, does NOT make it a 'custom', and is rather demeaning to the true 'custom' builder... but still...
Indies are erratic....
Back to top...
You MUST have a flasher-unit.. go find it.... but indies flash... so its probably not faulty.
You have NON-STANDARD indicators front and rear... LED 'arrays' I will assume, in the front.... and tungsten-fillement bulbs in the back....
This aint going to help matters.... with a conventional electro-mech flasher unit, original post implies you DO have some-where on the bike, the flash-rate is wattage dependent.
If LED arrays have been fitted in the front, they will almost certainly have a far lower wattage than the original bulbs..... at the back, who knows.... likely that an after-market accessory 'mini' indy will have a lower wattage bulb in it.. who knows what any of themn would do to the flash-rate....
A-N-D.... the low-rent answer to a load-dependent LED indy is the use of 'ballast resistors'.. that do not a lot but draw watts, to briung the load on a circuit back up to that of the original bulbs, and get the desired flash rate back.....
This than demands that original wiring be chopped to splice the ballast resistors into it... there may be one for each indicator lamp, or there may be one for the entire circuit... depends who did it, and what they thought 'easiest'.....
But means that wiring is likely to have been cobbled by some-one in the past.... a-n-d more low-rent practice is to use cheap and nasty Halfords Odd-Pack crimpy connectors, probably fitted to wiring with a horrible pair of plate steel stripping/crimping pliers.. or worse... whatever pliers or hammer and brick were to hand at the time.... or worse, twisting wires together and maybe covering with insulation tape.
Risking Polarbear's wrath, ISTR he has defended crimpy-connectors many times in the past..... but I still cant stand the ruddy things, and HATE with a loathing, the cheap-and-nasty odd-pack types so commonly used, where not even fitted with proper care and attension and a decent crimping tool... they ARE a problem looking for a place to happen.....
BUT we are back to advice at the start..... it's your bike, its your problem, you got to fix it.... GO CHASE WIRES!!!!
Check contacts in the bulbs, CHECK bulbs... PROPERLY, look for the obvious and common niggles and bodges like in-line ballast resistors and chit-crimp connectors and or wads of twisty-tape joints.... find them earth points, make sure they actually making an earth connection, and aren't broken or rusted to heck, or again, cobbled up with a crimped on ring connection on a rusty wood-screw.
Flasher unit! As has been said there MUST be one, some-where, and it would SEEM to be doing its job.. lamps... like-wise you have some... and if they light, tha'ts all they do... Switch, turns them on and off, thats all IT does... these devices SEEM to have been eliminated as cause of problem, so it HAS to be in the wires... GO CHECK! ____________________ My Webby'Tef's-tQ, loads of stuff about my bikes, my Land-Rovers, and the stuff I do with them!
