Ive got a 95 f3 that i just picked up. It wont start in the morning (7:30am) but when i get home from work (5:30) she starts fine. Choke works and i blip the throttle, like what seems to be a regular deal with the bike. If i get it to start in the morning, shes fine for the day. As far as runability, she runs beautiful. Any suggestions would be helpful.

 

Full choke in the cold mornings?

Do you give like 1/8 throttle to start it with joke?

Idle speed set to 1300rpm?

 

Just a matter of working out your bikes particular starting routine, they all have their quirks.

 

Yeah full choke when needed on cold mornings, with the 1/8 throttle. idle is set, ive even tried raising the idle to help it. I cleaned the carbs when i bought the bike (MMI graduate). Thats why im asking for help, i dont even know where to start b/c of no runability problems that i can feel.

 

Also sounds like you may not be getting any fuel. But that don't make sense because it starts later on in the day. Hmmmm! Re-check your carbs, spark plugs, & fuel pump. Won't hurt to check your charging system also. Battery, stator, R/R. Last but not least, ram air tubes, make sure their not clogged. That's all I can think of, good luck.

 

Sounds exactly like my bike. Just cold after sitting all night and it stays at a higher resting temp during the day, so its a quick start/warmup in the afternoon. That's my daily commuting routine and exactly how my bike behaves. I wouldn't pay it any mind if it runs fine once it's warmed up.

 

if it fired up in the morning i wouldnt be so worried about it but the fact it takes a while (15-20 min) for it to fire bothers me. Thank all of you for your advice. Keep the suggestions comming. If/when i figure it out ill let you know.

 

As mentioned, check the plugs for wear and gap them if necessary. .031-.035''

 

Hey, I have a similar issue with my 94' CBR600. Living in Britain it's always cold here but first thing in the morning I have to have full choke on. Anything less than ultimate full will just clock out on me after a couple of seconds.
I've found it takes me 5-10 minutes before it is ridable.
I'm going to get my carbs synced and cleaned soon so hopefully it will fix my problem. let us know how it goes.

 

Just wanted to update you guys, Last night i replaced the r/r, its connector and the plugs. Rode the bike. this morning i went out to go to work and it wouldnt fire, just like before. It seems like its not getting spark.
