kick-start not working when hot

[ZorsT]

heya
I just found out (after stalling while trying to do a hillstart in 2nd) that my bike (1998 RG-150)doesn't want to start with the kick when the engine is hot. I can kick all i want but i have to crash start (it starts fine with a crash start). It starts first kick when it is cold, or after a few minutes (like after i get petrol). Anyone else have this problem?
THanks

EDIT: maybe i'll just not stall :)

take it to the top of the takaka hill and burn it as a peace offering to the biker gods... then from that moment on it will NEVER happen to you again!!!


on that bike
:rofl: :rofl: :rofl:

Do you mean the kickstarter doesn't work,or the bike won't start?

If the kickstarter is slipping when hot then the clutch is slipping,you'll have to adjust your cable,or clutch,or replace the clutch.

If the bike is just not starting when hot I'd look at the mixture,it could be too lean or too rich on the idle adjustment.

A little trick I was taught was to hold the throttle on full and start it up, for some reason when it's hot my bike will only start that way.

Hope it helps. :)

FROSTY: My bike is too good to burn as a sacrifice - but thanks
MOTU: It is just that it won't start with the kick - I'll look into the idle screw, i think it idles too low - thanks
CSL: I'll try that tomorrow - thanks

The kickstart idler gear meshes directly to the gear on the clutch basket that in turn meshes to the crank. Clutch has nothing to do with it or you wouldn't be able to kick it over with the bike in gear and the clutch in.

That means the bike is too rich,full throttle clears it out,possibly what is wrong with the original pos's biket,but he's still not being clear on symtoms.

An RG is a 2smoker? There's your problem :devil2:

If it won't fire up when hot, a change of fuel octane might help.

[White trash]

Chuck a new sparkplug at it.

And if that doesn't work, remove the old plug and install another new one (not the thrown one)

[ZorsT]

when it is hot, i can kick and kick the starter, the engine just won't fire. When it is cold, it fires first time.

RR: The owners manual says to only use high octane, I run it on 96
WT, do i need to buy two new plugs then?

[White trash]

It sounds almost as if the mixture is too rich, as Motu suggested.

we all get a little bit too rich at some stage in our live's and then we go out and buy a motorcycle, it's down hill from then on,but surley that's a good thing if your kick start don't work Hmmmmm..

Could be spark timing.

I had an old Honda with that same problem. Started easy when cold but not when hot. If it didn't start within first couple kicks after stalling, there was a 15min wait for it to cool down or go find a long hill slope to crash start.

You should burn it LOL

Ah yes, shades of the old Yamaha YDS-3 250. Also, the oil pump and rev-counter stoppped working when you pulled the clutch in, so sitting there at the lights for a while in gear revving up produced nasty things to pistons.. :devil2:

Yamaha has had some interesting designs over the years.

The owners manual is crap for these bikes. Written by some Under paid guy from Thailand, with a poor grasp of English. It even contradicts it's self in places.

I had a RG150. Used to run on 91 fine. Both on the street and the Race track.

Also had a similar problem with the KR1 250sp when I got it. A Bitch to start sometimes. Changed from Ave gas, to 96, to 91. Normally started easily on 91. (91 being a faster burning fuel, effectively changed the combustion timing) (lots been written about octane : Do a site search; lets not get into that again here!)

Then again, it could be running rich as they say.

PS. Time to change your profile pic. :yes:

I found when I first got my 2 smoker i had inadvertently left the choke on just a fraction causing it to die when I stoped at intersections etc and would be a real b@stard to start- had to hold throttle open to start.
Make sure choke is fully off before you ride.

[ZorsT]

thanks people for all the replys, it seems i will try different fuel for a start, if that doesn't help then i will fiddle with the idle screw, and if that still doesn't cure it, i just won't stall :yes:

Its to rich.
ie the fuel levels to high,or the carb needle and seat are worn , leaking ...or airfilter is badly blocked .

Japanese bike are designed to run on 91?? unleaded ie the cheap stuff we call it regular here, the higher octanes can tend to cause could fouling, ie deposits on the plug causes a waywould spark

Ps doesnt hurt to put a new Plug in ( a number up or down wont make much of a diff ,

An RG is a 2smoker? There's your problem :devil2:


There oughta be a law! :rofl:

[ZorsT]

There oughta be a law! :rofl:
...against flagging off 2-smokers :oi-grr:

[FROSTY]

-before doing anything --When the bike is hot pull the plug out and look at the color of it.that will tell ya a heck of a lot.
Ohh and--what did I say before??

[ZorsT]

Ohh and--what did I say before??
umm... Pratice, pratice, pratice, breaking, brakeing or brakeing, escape routes, practice, umm... to be organised when trying to change the oil (put the drain bolt back in etc)

You've said a lot Frosty. I must read all of your posts again!
Definitely all the time while riding or doing maintenance, it's like I've got a little parrot on my shoulder saying Frosty said this and that.
Good on you Frosty! :clap:
You're making better bikers out of us many junior riders.
And good on all the other KB members, collectively we're all getting better as most questions and answers get answered!
Keep it all up Ladies and Gentlemen.

Sorry to bring up an old thread, but I also have some RG fuel/spark questions.

I've been putting high octane in it recently, and found that it has a weeny bit more get up and go, but also more of a propensity to bog down ie. if I'm not careful about slipping the clutch taking off.

What is The Word about fuel for RG150s?

Could it be helped by replacing the plug? I think the previous owner(s?) was a bit of a lazy bastard when it came to maintainence, and the plugs likely fouled to fuck.

Is there a good plug recommended for RGs? (and how much am I looking at lol?)
