Have I killed it already - RS125

[Millsie]

Recently acquired an RS125 1997, have been going for drives over this weekend. Today went out for a drive, stalled a few times (getting used to gears) but once I got going I was okay.

Then coming down a hill (in gear) the bike wouldn't accelerate anymore, while the bike was still in gear we slowly came to a stop. Tried to use the electric starter, no go - just wouldn't catch & ignite/fire. Tried to bump start it in first down a hill, felt like it should have caught a few times, but just didn't.. Came to a stop again..

Pushed it all the way home and now I notice I can get the bike easily into first, but then struggles/won’t get into 2nd, usually slips back to Neutral. (Researched around and some commenters mention a clutch pin?)

A few nice people came over and gave me a few things to look over.
1. Fuel like blockages i.e. no fuel getting to cylinder.
2. Flooded carb
3. Fuel getting to spark plug/spark plug has spark

Sorry for the novel, any idea what I have fucked kb? :mad:

TLDR: Bike won't start(bump start won't work same with electric start), hard to get from first to any other gear

[sil3nt]

Did you run out of fuel?

It won't change gear unless it is moving.

[Millsie]

Did you run out of fuel?

Unfortunately nope, got tonnes of fuel in the tank.

Also thought about possibly flooding the bike, was going to empty out the carbs but couldn't get at them & didn't exactly know how to drain them with this new carb

Reaaaally? I though as long as you used the clutch you could cycle through all the gears

[Madness]

One doesn't take a motorcycle for drives. One takes a motorcycle for a ride, a hoon, a fang, a blat, a run, a blast or a pootle. This list is not exhaustive, however the phrase drive is quite unacceptable.

As for the RS, I'll give ya $5 and a bag of chips. She's fucked.

Reaaaally? I though as long as you used the clutch you could cycle through all the gears some kawasakis are like this designed so while stationary you can't accidentally change up into second, pain in the arse if you want to crashstart a bike, anytime i've been in a motor with this i've removed it

I'm very sorry sir, I'll make sure to use one of your terms instead of drive :not:

Cheers for the optimism, make it two and a new RS125 then we've got a deal.

Shit alright, learn a new thing everyday..

Hopefully this doesn't take too much to fix >.>

Anyone know a good 2stoke mechanic? hahahahaha

[Asher]

Fuel tap was turned on? tried it on reserve?

Were you just cruising around in the lower revs? You could have fowled up the plug, two stokes especially ones like a rs need to be given shit to run well.

Pull the plug out and check it not covered in carbon or too much oil and while its out check its spark by turning the engine over and looking for a strong blue spark.

I'm going to go triple check the fuel now, hopefully it's that simple & im just... forgetful?

I lightly hit the power band (farest I went was 9k), going to try and take that out now, I wonder if I have the correct size spanner for it.

I was only riding for 10-15mins gaaaah

where abouts in wellington are you?

[tigertim20]

Remove spark plug.
throw spark plug in rubbish bin
put new spark plug in.
go riding.

Id bet its simply a fouled plug. should always be the place to start with 2 stroke running issues in my experience

[Millsie]

Newtown, real close to the hospital.

Right! Lets just hope it's that.. Gonna go grab some new tools to make this easier.
If the sparkplug is fouled then is it is simple as hitting the powerband more frequently or is it possibly an incorrect fuel mixture?


Fuck I'm happy I have a Haynes manual, i'd be ripping my hair out by now if it were for it

[Drew]

Buy two plugs for it. wrap one in a plastic zip lock bag, wrap that in a rag, and stash it securely under the seat. Fuck pushing a bike for want of something as simple as a plug.

Plugs the first place I would try were I you, then see if there's fuel in the carb. Anything more complex is beyond the written word.

[unstuck]

And once you get it running, flog the shit out of it for making you push it. Really wring its neck. As long as you stay within the law of course.:whistle:

[Millsie]

Alright things learnt from lifting up the tank/checking spark plug:

1. Fuel taps need to be turned completely around to stop the fuel from gushing out.
2. Fuel lines need to be long enough for the tank to be lifted up.. (This fuel line eventually got cut, I couldn't wiggle/rip it off the carb or the tank - it was about 9cm long -.-)

Got the spark plug out, tiny bit of oil and carbon on it, expect that's normal.
Plugs got heaps of spark, unforuntately.
Checked the cylinder as well, still compressing/moving the piston around.

Now I find it hard to put the bike into first from Neutral..

Any ideas? :(

[Drew]

Any ideas? :(Pull the filler cap off the gearbox oil, and sniff it.

If it smells of petrol...ummm...you might have fucked it.

How do you feel about 'strop' or 'scoot'?

[mossy1200]

Spark and compression and fuel/oxy should equal go. So your no fuel or hole in piston. Drain gearbox oil check for fuel and or piston pieces. Maybe reids or power valve fault causing fuel issues.

Two stroke bro. Be catastrophic if there was piston bits in the oil.

But fuel in there indicates fucked crank seals=bang.

[blackdog]

You could have fowled up the plug...

There's the problem right there. It will never run right with a chicken in it.

Yah lol its rs125. No way the piston could leave the sleeve head south and have a rod try and hide it.:crybaby:

Buy two plugs for it. wrap one in a plastic zip lock bag, wrap that in a rag,accompany it with a spark plug tool and stash it securely under the seat. Fuck pushing a bike for want of something as simple as a plug.



fixed it for ya

its a two stroke, you should start it up, let it warm up, then thrash the fucking thing like a cheap whore untill it runs out of gas. then repeat daily.

this is excellent advice for a 2 stroke owner!!!!

ok firstly, do a quick google search on 'reading a spark plug' then compare your plug to the chart, its real simple to see whats going on.

secondly. a spark plug can spark quite happily outside the cylinder when testing, but still not run when put back in the bike. throw the plug away, they only cost a few bucks, and try again, that way, at the very least, you know for definite that the plug is not the issue.

when you are trying to change gears, are you just sitting on the bike? you need to rock the bike. i.e. from nuetral, roll the bike slowly forwards while trying to put it into gear. Bikes do not particularly like someone trying to make then go into gear when they are stationary, and even less so when they arent running at the time. I could explain this in depth to you, but it require you to have an understanding of murphys law and black magic in order for you to understand . . .:lol:

Let us know whats happened after you throw the plug away and try with a brand new one . . .

[BigAl]

After trying to start it, remove plug, does it look wet & smell of gas? If so then fuel is getting through.

You said it sparks so electrical prolly ok.

Try removing air cleaner & try to kick over, maybe blocked filter.

Could also try spraying some engine start/start ya bastard directly in air box and try starting.

[jellywrestler]

Onya fella.:hug:

only cause i went to change a set of plugs at the whakatiki hotel less than a month ago and while i had four new plugs and a plug tool it would only do the outer two plugs...

[jellywrestler]

You said it sparks so electrical prolly ok.

not to say the timing may have slipped for some reason,l had that in the middle of winter last year on the rimutakas, bloody taper fit on a lucas mag and the nut had come loose, yep my doing too!

[Taxythingy]

For sparkplug images, try this: http://www.dansmc.com/spark_plugs/spark_plugs_catalog.html

Is there a filter after the fuel tap? This could be clogged full of shite/rust.

Mossy and Bigal are on to it - spark, compression, fuel, air.

Did the plug smell of petrol when you pulled it out? Yes = fuel getting there.
While the plug's out, stick your thumb over the plughole and crank the bike. If you can't hold it there you have compression (some).
Do the airbox thing.
New plug for good measure - my RG150 would foul them up a bit & always ran better on a new one. $7 vs. a couple of hours of pissing around?

A good read through Dan's guide to bikes that don't start could help. http://www.dansmc.com/troubleshooting2.htm

Just quietly that's probably my funny used up for 2013, thanks for the set up.

Either way, it was magnificent.

You've done well, not to have squyandered it before now. Nearly eight months into the year an' all.

[Millsie]

Well shit, this thread diverted off hahaha

Turns out it was the spark plug, threw the new one in took some advice and ordered two, going to throw the other under the seat and build a tool kit to throw under the seat too.

Fuck yeah for a cheap fix, cheers for the help everyone ;)

Drews still saving his one up

[SMOKEU]

jews did it.

They fucked my carbs by forcing unleaded fuel upon us too.

[F5 Dave]

yeah 'cause all our petrol comes from Israel:eek5:

Too many carbs will just make you fat anyway.
