RG150 broken?

[Magua]

My engine's proper fucked. Big end, crank (I think, it was a bad line), Crank seals, some other things mumble mumble, which totalled $800 in parts and $400 in labour. $1200 work on a $1300 bike, no thanks.

Anyone got an engine?

do it your self?? there is a manual on here some where that you can download. Its a two stroke. Very simple.

you should at least pull it apart and find out how easy/hard it is.

Im sure someone from around your area could give you a hand??

other wise how much do you want for the fucked engine??

[Magua]

Even if I was to do it myself, $800 in parts. If I can get a new engine then fuck that.

Umm, how much would said engine be worth to you rg100?

[Sketchy_Racer]

to me? weeeelllll

a dollar maybe,

But to you its worth closer to a $X00

[Magua]

Just picked it up, official verdict is "Check for clunking noise coming from motor. Report big end worn out."

New is the keyword here... don't buy a second hard piece of crap that's been screwed and won't make another 5000kms. Sometimes it better to swallow the lump, spend the $1200, and have a nice reliable full power engine that'll do the distance

Remember, it's a 2 stroke, they don't like to be mistreated or inadequately maintained... don't buy a lemon!!!

oh and how much would it cost to get the Crank rebuilt rather than replaced??

Hey Magua, this has me a little concerned.

I was wondering if there was any reason for the big ends to go like that, was there enough oil and what quality etc? I ask because my RG150 has done significantly more KM's (44k) and I dont like the prospect of it crapping itself with me on it.

Do you know if you had much sideways movement with the conrod at all, I had a little when I pulled the head on mine.

[Magua]

Can't say I know what a conrod is.

I think mine went as there was something wrong with the oil pump. I'll confirm when I pick the bike up tuesday. It's ready now, but my tertiary account isn't.

[FruitLooPs]

That'd be fantastic thanks, because Im thinking maybe I should do the bearings on this thing but its previously had work and the oil pump is def working.

The conrod attaches the piston to the crankshaft mine could wiggle a tad left and right, and I do get a strange noise when i'm going along - not clunking but not just the usual loud 2-stroke noise.

It goes fine and isn't getting louder so I think i'm just worrying. I *do* however have a rattling/buzzing sound from the engine, and i pulled the head and retightened it and it went away for 2mins or so lol >.< i'm fairly sure its nothing rattling in the powervalve box since i just pulled it to bits and loctited the screws (they had come out).

Sounds like metal rattling on metal really quick, like vibrating.

[Magua]

I had that buzzing noise too. I'll see if it's still there on tuesday. Mine was buzzing from day 1 (11,000kms, died at 14,000).

Houston we have a problem!

I changed the trans fluid 3 weeks ago approx, ditched the old and stuck in some new. I only had a 1L and it takes 1050ml I thought meh wont worry about it. Stuck it all in, the manual wanted it overflowing but it was only 50ml short.

So today I buy another 1L to fill it that extra 50ml and .. 300ml in wtff 500ml in oh ughh alllll 1000ml in... Aghh where is my oil going!? it must've been running dry for a while. Even after the second litre it still isn't topped up to overflowing lol!

No the sump plug wasnt out, no there wasn't any leaking out

I talked today with my friends dad who was an auto and now an aeronautics mechanic. He told me it sounds def like the crank seal has gone and I will need it fixed really quick if I dont want to do a bearing (or the engine like in your case magua).


Any idea what the cost of the crank seal was magua? if I do this i'll probably do the big end at the same time rather than risk it. I've already stuck new powervalves into it - so i'm half bloody way now lol. I'm just glad I haven't seized it or screwed the whole thing. If I'd topped it up the first time I dont think i would've checked it again now and probably would've blown the engine, so that was lucky ... in a depressing kind of way.

Oil Seal 25X36X6 - $21.33
Oil Seal 36X52X7 - $53.33

Could be one of those two, I'll scan the invoice tommorow.

i'd wager that buzzing/hissing/rattling sound is the munted seal.

Mine never used to do it when you started this thread, but my bike certainly sounds more like yours now (its not clunking, but its not smooth) so I dont think i've damaged anything but i've certainly got a munted seal.

At the same time my idle has risen from 2k to 4k and it slowly drops down to 2k after sitting. When I first did the oil change, it was straight after changing my powervalves - there was no or had only been that sound for a short amount of time.

The oil that came out i'd say is 900ml or so, i didnt notice at the time. From then it would've been drinking it, im glad I noticed! I'm not sure if i should ride it at all now, even with regular top ups and babying until i can pull it to bits.

I intend to do this seal myself, if its cheap enough.

I've been involved in fixing Rg 150's and have brought many back from the dead. 2 years ago we had 3 RG's racing in the South Island, we know have exactly 50, and I pretty well know the history of all of them. They are very reliable, but we now know of some basic "dos" and "don'ts" relating to keeping them this way. You're welcome to pm me for contact details and I can help you specifically.
