I installed a set of Fiamm Highway Blaster horns once. To make them loud you need to install the optional sub wiring harness with a relay. This steps up the power and your motorcycle will sound like an American car from the 1970s.
Ja sam na mom autu imao fabrički Fiamm i taj sam bio ponovo kupio kad je originalni crkao, oba trajala po 10 godina.
Fiamm se pokazao odličnim kod nas doma
I swapped mine with a “FIAMM 72112 Freeway Blaster LOW Note Horn” just because I didn’t care for the stock tone. Cost was under $20 and took 5 minutes
Use the included relay to power them, the stock wires won't cut it. Use the stock connection to power the relay. You won't regret it. I've put these on every bike I've owned since 1984.
In installed these FIAMM 74100 horns on my son's 337. They are less that $20 on Amazon and work great. You need to make a jumper wire to go from the connector to the horn, but only for the +12v connector since the mounting bolt provides grounding.
Fiamm Freeway Blaster Horn #3830. This horn generates a shattering 132 decibels and will likely get just about anybody’s attention. I had two of these horns on my old '79 street Rabbit.
i put in a FIAMM from a 90s saab 9000 and its way loud now.
My car has been sitting idle for long periods due to lockdown. After two incidents where the 3-year-old battery was too depleted to start the engine after sitting for 2 weeks, I resorted to disconnecting the negative terminal when the car would sit for any length of time. Previously I was charging the battery up to 14.4V once every week or two (using a charsoon antimatter hobby charger which does CC-CV charging. Current limit set to 10A, automatic termination of charge when current falls to 1A @ 14.4V in CV stage). This week I did some research on the battery (a Fiamm Platinum 54Ah) and saw that the plates were both Calcium. I read that calcium needs a slightly higher voltage for full charge, so I raised the charge voltage to 2.46V/cell. Ambient temperature is 30°C in Malta. Now the battery seems to have developed high self discharge and is practically useless. I had to top up the battery yesterday to get the engine started. Parked the car at 10pm last night after hours of driving (and 2 hours on the charger). This morning at 6am the engine wouldn't turn over. Connected the battery to the charger, 5 minutes of charging later (only 300mAh put in) and the engine turned over strongly and started no problem. This battery has unfortunately been deep-discharged 3 or 4 times over its life (I think the car has a large standby current).
