RG150 broken?

**Magua** · 7th May 2006, 10:15

I was out on 22 yesterday (MR's ride) and my bike decieded to stop working. I was going at it pretty hard between the corners, fairly close to the red line when the bike starting making a bit of a humming noise, which proceeded to get louder until I throttled off and pulled over.

As I was doing this I started to loose power and then the bike stalled. Now when started it sounds rather terrible, sorta clunky, I might go kick it over later if I dare just to describe the sound better.

It's only done 14,000kms so I hope it's nothing too serious, I'll try and get it to a bike shop during the week sometime.

Not the best desription, but any ideas?

Edit: I noticed it had ditched a fair amount of fuel on both trailer rides it took, (it was standing upright on it's stand both times) if that's of any help.

Well, a traditional two stroker either seizes (problem obvious), or craps the big end, in which case they usually keep running OK but rattle like mad (until the rod breaks , anyway). Or break off a chunk of piston skirt, which is usually quiet , just no power.

Your description doesn't fit any of these so I'd suggest either something "odd", like an exhaust baffle broken loose ("humming") and then blocking the zorst. Or, the obvious candidate, just because I don't approve of them, those powervalve thingamajigs.

Either way, get somebody with experience of the motors to listen.

Does it still have compression? Start ? No (new) oil leaks ? Water leaks? Has the water level gone down? Up? Oil in the water?

Did you have the fuel tap turned ON when the bike was on the trailer?

If so, fuel was sloshing out of the carb bowl.

No water leaks, no new oil leaks, it started yesterday a few hours after the incident ( i don't want to start if I can help it), water is green doens't appear to have any oil in it.

sounds like your powervalves are 'rubbing' on the piston.

Just pull the head off and have a look. Its only a two stroke.... nothing to them.

Here's a video of the offending noise.

Im sorry, But i may be wrong (i hope i am)

But it sounds alot like a shat out crank. It is a sort of a knock from the sound in teh video.

Would you be able to get a a sound wave of it reving a little bit??

Just pull it to bits and have a look, you will sleep better

I don't have the tools stanko and after the fzr I don't know if I should be fucking with this one.

I've only got a digital camera rg100 but I'll talk to our friend pyrocam and see what magic he can work with a video.
Edit: tommorow I'll take a video, pyro will sort it. Legend.

Sounds somewhat worse than powervalves to me, the right one of mine had been munted against the piston at some point and has been bent etc, doesn't have any untoward sound like that though.

Whip the head off, I did mine today and its a walk in the park, seriously.

I've got all wednesday off so maybe I'll tinker then. In the meantime I've made three videos. It stalls out when I try and rev it, but pyro's changing them to soundfiles and I'll host them for rg100 to have a listen to anyway.

**Magua** · 8th May 2006, 16:03

Here's the sound files.

EDIT: Pyrocam is a legend.

**Sketchy_Racer** · 8th May 2006, 20:46

That Does not sound good ...

It does sound alot like the crank....... But it is weird how it wont rev.

I guess it only time to pull it apart.

Too bad you aren't lower down in the contry.... i would love to help out..
