[Inglés] Summary: I have a Honda Navi with approximately 20,000 km. I've done all the maintenance, etc.

The problem is that I had it unused for about two and a half months until today. I left the fuel valve open the whole time because I forgot (I know it's my mistake).

I tried to start it and the motorcycle won't start. The fuel valve is in the ON position, I changed the battery to a new Yuasa, I changed the spark plug to the original one, it has clean 95 octane fuel... And it still won't start.

I don't know what could be wrong. 😫

If anyone knows what it could be, please feel free to comment and explain my mistake or if I'm doing something wrong. 🫂

Thank you for your attention and time. I look forward to any comments. Thanks again. ✌🏻

[Español] Resumen: Tengo un honda navi con aprox 20.000 km. He realizado todas sus mantenimientos, etc.

El problema es que la tuve sin uso durante unos 2 meses y medio hasta el día de hoy. Deje abierta la llave de paso de combustible, durante todo ese tiempo por olvidó (Sé que es un error mío).

La intenté encender y la moto no arranca, tiene la llave de combustible en ON, le cambié la batería por una nueva yuasa, le cambié la bujía original, tiene combustible limpio 95 octanos... Y aún así no enciende.

Desconozco que le puede estar pasando. 😫.

Si alguien sabe que puede ser, no dude en comentarme y explicar mi equivocacion o si estoy haciendo algo mal. 🫂

Agradezco su atención y tiempo, quedo atento a cualquier comentario. Muchas gracias nuevamente. ✌🏻

Hello, everyone! I am looking for some advice!

I rode my '22 Navi home from work and the next day it wouldn't start. So, I started to troubleshoot.

I checked and even swapped batteries from one Navi to the one that won't start and it didn't help. I changed the spark plug. Still, nothing. I know I'm getting fuel to the spark plug as the new one was wet with gas when I tried cranking it up.

When I checked to see if I was getting a spark to the spark plug, I noticed there was no spark. I checked fuses and couldn't find anything wrong. I ordered a new ignition coil hoping that might be the fix. Wrong.

I put the new ignition coil in and still, I'm getting no spark to the spark plug. This is despite the battery being fine, gas getting to the spark plug and the motor trying to turn over.

It won't turn over with the kickstarter either.

Any guidance/helpful information would be greatly appreciated!

Thank you for your time!

TLDR; Not getting spark to the spark plug after changing the battery, spark plug and ignition control

I do Uber eats on this bad boy and put about 100 miles a day and make about $100. Today I paid for my gas with change laying around my room.

Now my 50W (35W LOW + 15W HIGH) H4 Bi-LED don't flicker anymore when I use hazard lights

I used 2 relays for both High/Low Beam, but you could use only 1 relay for Low or high Beam

PLEASE COMMENT IF YOU NOTICE ANY MISTAKE ESPECIALLY FOR HARNESS

Materials used:

• 14AWG Wire (16 is fine)
• H4 Female Socket
• H4 Male Socket
• Automotive Fuse Holder w/ 7.5A Fuse (Calculate first, if you use higher watt lights you might go above 7.5A, got the standard fuse holder but mini is better if you want same as stock)
• Ring Terminal + Splicer/Crimper (For battery terminal)

I use automotive 4-pin horn relays and wired as follows:

Relay 1 (LOW):
30 → Battery + (fused)
87 → H4 LOW filament (female H4 socket low beam pin)
85 → Battery ground (Wire it parallel with H4 Male and Female ground)
86 → LOW trigger of stock h4 harness (male H4 socket low beam pin)

Relay 2 (HIGH):
30 → Battery + (fused) (just wire it parallel with relay 1 #30)
87 → H4 HIGH filament (female H4 socket high pin)
85 → Battery ground (just wire it parallel with relay 1 #85)
86 → HIGH trigger of stock h4 harness (male H4 socket high beam pin)

When you wire it successfully, it will produce satisfying loud clicking sound (both relays click when you switch)

It works by getting power directly from battery, uses H4 sockets to get signal to trigger the relays, no more shared load to your H4 = No flicker!

WINKER HAZARD MODE BONUS

Note: Winker lights and winker relay is stock, as they are completely compatible with hazard, just not included)

What I did with winker hazard:

Got a universal 3-wire switch for hazard (clamp type to handlebar)

My 3-wire switch have 3 wires - brown, blue, and black

Where: black = goes to switch (please test first)

Trace the winker lights wire, orange (Right) and sky blue (Left) (Test first please)

Wire the black to winker switch (gray but please test first), then the rest of the wire to winker lights (don't worry about what's left/right, they will still wink together)

Note: Stock halogen bulbs are 21w * 4 (approximately 104W total load each wink). However, the stock winker 4-pin relay seems like a heavy duty one that could take 21w * 4 max at the same time.

It's been weeks, I forgot the actual color coding for winkers for both L/R, please correct if I'm wrong.

Fused H4 Relay Harness Kit

You can hear the relays click very loud/No flicker when using hazard or loud horn

I bought a new Navi in early 2022. I have around 256 miles on it. Rode it a few times every year. Changed the oil in summer of 2024 and the other day, still have old gas in it from 2024 or 5. I charged a couple batteries, and they both crank and show the brake lights and turn signals, and when I try kick starting it, it doesn't do anything. The standard start just has a cranking noise. I drained around 3 oz of old gas- the first ounce was grey and slightly cloudy. I used a lot of rich fuel to start it in the springs and falls, and even changed the oil the other day (2nd oil change in 4 years). I checked the screen- no debris/metal shavings, and the oil was still clear from 2024, since I only rode it maybe 5 miles in 2025 after the 1st oil change. I've been able to use year old oil before, even 2 year old oil, but I think it's the spark plug- I used the stock socket wrench to access it, but I've been hesitant on pulling it out. I might buy a new one anyways. I have a new battery arriving- I changed out the old one a year ago- using just a lithium one, although it's starting capability is not as good. I'm thinking it might be a possible loose wire, but I think it's possible the jets are clogged. Wish it weren't so easy to jam- maybe a gas station that shares the pump for E10 gas with ethanol free, I'm not sure. The last time it started was around a year ago (Maybe early summer).

I wanted to ask what size the multivar 2000 uses. I read it was 19x15.5mm does anyone know if there are slidersfor it that are 16grams?
