Another problem thread... (RG150 problem)

**TCN** · 19th March 2008, 18:48

Hi everyone,

well, im stumped by this problem, cant figure it out. Ill be riding around town on my RG, when all of a sudden the bike starts to "chug" and jerk, like its starting to run out of fuel. after a few seconds of this, the bike just dies, no responce from the throttle or anything. I pull over, check the fuel cock, gears, etc etc, then try to start it. It takes about 10 kicks to get it going, when it usually takes 1-3. It seems to go fine for about 5-10 mins, then the same happens again. The fuel tank IS full btw, and ive pulled the carb out (it was missing a screw off the fuel pan, and want even held on properly!) and cleaned it/checked it. I got a new inline fuel filter, ive cleaned the in-tank filters, ive cleaned and reoiled the air cleaner, ive done evrything i can think of, yet this problem still occurs. Its usually doing about 4-5k revs in 5 gear.
Ive also noticed the temperature gauge barely move when riding it. Should i blank off some of the radiator to get some heat into it? im really confused.

Thanks!

fucked coil?

Well, for a start why on EARTH are you doing 4 -5 thousand rpm in fifth gear (or any gear for that matter).

It's a ruddy two smoker. RAPE IT.

I'm guessing the little smoker is fouling its plug and going into a well justified terminal sulk at such abuse.

There are only two engine speeds on an RG - idle and red line. Everything else is just on the way.

Poor, poor little RG.

**FJRider** · 19th March 2008, 20:06

check the plugs, the oil pump to the cylinder may put a bit extra through and foul them. check spark at the same time, as well as spark GAP.
2 strokes need revs so if it does it again, change DOWN a gear or two. Whats your redline ??

**TCN** · 19th March 2008, 20:22

Ill check the oil pump tomorow, but surely if a plug fouled, it wouldnt start till you cleaned it. Redlines about 13,500. Spark plug and gap have been checked, all fine. So what, your saying i should be cruising in 2nd or 3rd gear, doing 10,000k? that just seems stupid. The bikes only done 12,000kms btw.
Ill give it a fucken good warm up tomorow, and see what happens. Anything else?

Yup. Exactly that. Redline @ 13500 so try to keep it between 13000 and 13500.

You've never owned a two smoker before , have you. Logic is irrelevant. It's a two stroke. Like a woman. Whatever you are doing is wrong, you've upset it somehow. Rape it.

My RG runs like a complete sack of shit unless i ring it's little neck, especially around town - I never get higher than 3rd gear on the way to work! I took it for a run to Miranda for the first time on the weekend and was redlining it most of the way (Ermmm - except for the really twisty bits

haha) and it's running better than ever has before. Moral of the story - RGs love the redline

**Grub** · 19th March 2008, 20:57

TCN, you have to take the hits along with the good stuff here - it's not personal, people just don't know how to play nice sometimes

It sounds to me like you have a fuel problem even though you have done the usual things to clear it. I wonder if the vent to the tank is blocked/kinked. Get your mates bike alongside yours. Take the hose from the tank to the carb off and open the tap. Does yours flow as well as his? If not, it's blocked or the vent isn't working. That means the carb's float bowl isn't staying filled. When you stop, the trickle flow fills it and off you go again ... slowly draining it.

Now, who's going to break the news to him that his power band is perished and needs renewing.[/QUOTE]

Haha, and that they chew through powervalves quicker than a fat bastard eats pies

**TCN** · 19th March 2008, 21:07

Thanks grub, so im guessing the fuel should run out of the tap in an even stream? I dont think the breather/vent pipe is blocked, coz i blew through it, and there was no resistance. I saw a thread about someone having low speed problems. They said that the low speed jet might be blocked, causing fuelling problems. Gah! ill give it a fang tomorow, see what happens...
yea haha ixion, very funny...

Each bike's different which is why I thought doing it alongside your mates bike would tell you. But yep, it should. It may not be the fault but hey, when you're scratching for a solution I'd try everything.

I know a mechanic that tried for 6 weeks to get an Aston Martin restoration job running properly. He finally found that the fuelcap vent hole had been painted over. It explains why he's bald I think. I've never forgotten the lesson.

**TCN** · 19th March 2008, 22:05

it hasnt happened when im on the open road though. grrr, ill check that tomorow. ill also try the other solution these people had...
oh yea, another thing is that you can feel the bike surgeing while doing 100kph. you feel it accelerating then stop, then accelerate, etc. Its hard to notice, but it always does this. any ideas?

it's a 2 stroke. if you don't rev it the oil doesn't burn off properly and the whole exhaust system blocks up with oil. it's a fact and that's why 2 strokes really aren't very sensible decisions for commuters (along with the nasty powerband - pretty weak on the rg150 but more of an issue on a 250 in the wet - and excessive fuel consumption)

you should be revving it - and yes you'll look like a dick to all the car drivers/pedestrians who don't know any better as they cough through the blue haze you leave everywhere you go.

now that does sound like a fuel problem, but 2 strokes never have logical explanations... in my experience they can just be throwing temper-tantrums.
