Honda hornet 250

[NOMIS]

I've had issues with mine, was cutting out. Found out to be a cdi unit, so I've got another one & replaced the regulator to be on the safe side

1st ive heard on this problem... 1st i have ever heard on any prob on the hornet. One thing I do hate about my hornet thought is kicking back into neutral from second gear when giving it shit.

[kimjie]

yeah i've got that same situation the other day.... first.. it won't start... so i've checked everything on it... the gasoline switch (had reserve and gas on, my baby is a bit old... so no gas gauges) but it won't start that fast... 2nd part was... i experienced 2x engine stall... don't know why... just riding my bike back home it's in stop light so have to slowdown and put it neutral... got it in neutral but the engine just drop dead ( engine stalled!!!) dont know why... if anyone out there know why it would stall give me some advices.. Gijoe... hope you know this you too Nomis...

hope everyone could help

Have you checked the battery? If it isn't that, trace back to kill switch, may have to dismantle and give it a quick shot of electrical spray. If it isn't that, may be CDI unit.

How many kms has it done? Sparks may need some attending to ... I hates lecky probs, always a fault finding exercise and it turns out to be something simple (hopefully most of the time!)

it got 24 thousand ++ on the clock... and it has been overhauled (carbs front fork) new chains... all electrical is working... sometimes it's hard to start too...the first time i got it... i took it for a spin...and i kinda hit it... pull it up from 2nd gear to 4th gear straight 10k rpms... and my friend saw some black smoke came out of the pipe... i was thinking about the carbons on the muff just got dust off... but it rattle me brain about that plugs... new oils... (just dont know the plugs if it's still alright or not) me not a mechanic though i want to learn... i know it's hard to remove everything to replace a plug (mainly the tank) hope know a lot more...

thanks for helping...hope not to bother anyone else... lolz

S'alright to ask questions, keeps the noggin' thinking and maybe someone got a solution thunked already! Heaven knows I remember the probs I have had to ask here and got some durn handy help!

Those are prob the first set of plugs and they do go phut everynow and then (usually need to be changed around 30 000kms). Might be worth checking them out if only for peace of mind (I know when my little ol'hornet lost power and wouldn't start was due to the sparks being clappered out!)

Not too hard to remove the tank, just a single bolt in the rear to remove and just a matter of removing the fuel line and vaccum line from the fuel petcock.

Then gently ease the tank off to the back from the two rubber bungs on the frame. If you look under it, you will see the mount point.

Do you know any aftermarket plugs? and if yes have you got plug numbers?

Best to stick with what the manufacturer specified. If you're feeling particularly flush, you can buy the uprated iridium-tipped version of the same plug, which is supposed to last much longer and be more resistant to fouling.

Thats what im after. just want to know a part number so i can get the local repco to get em in, I know NGK make them And I got 2 seperat numbers . But im not sure which is correct and if there a iridium version

Ah ok -- CR8EH9, which are ludicrously expensive IIRC. The iridium version on NGK, there's usually an IX chucked in there somewhere. Probably the CR8EIX would be the correct iridium version, but I'm not 100% on that.

Thanks alot for that

[NOMIS]

Got part number now.

Standard - CR8EH9
IRIDIUM - CR8EHIX9 .. NGK plus for honda hornet250

vaccum line that's the fuel line right... and that petcock is what??? if i did got the tank out... would it spill some fuel??? on the carb and on that fuel line...??? this would be embarrasing but could you take a picture of it... lolz... this would be much of help not just only me but some other hornet newbie riders out there too if they got some prob's just like mine...

thank you for helping... hope not too much of a pain in the @ss lolz...

The Hornet 250 has a vacuum fuel tap. They're a bit more complicated than the normal ones, but they work like this. There's two hoses, fuel hose and vacuum hose. If you turn the tap to On or Reserve, there's a rubber valve that won't let any fuel through the tap out into the fuel hose. However, if you pull a vacuum in the vacuum hose by starting the engine, then the vacuum created by the engine in the vacuum hose will suck that rubber valve open and let fuel through. Switch the engine off -- no vacuum in the hose, so the valve stays closed and no fuel will flow.

However, you can bypass that rubber hose by turning the tap to Prime, and fuel will flow no matter what.

So, in short, if you leave the fuel tap set to On or Reserve, when you disconnect the hoses and pull the tank off, fuel won't spill (maybe a tiny bit from what was left in the hose, but that doesn't matter).

so in short i'll just put it on OFF then it will be easy and secure to remove the tanks??? or it's vice versa... put it to On or Reserve the fuel inside my tank won't spill out???

[xwhatsit]

Oh, wait, what? It's an On, Off, Reserve tap? If so, just set it to Off. No fuel will come out the tap when you unplug the hose.

I thought it was like GiJoe1313's Hornet -- On, Prime, Reserve. In which case you set it to On or Reserve, then fuel won't come out the tap.
