RG150 smoking up a storm!

[samurai jackson]

So I have a 98 RG150 that I picked up on trademe. Its a tad rough but has potential. The problem is that its fouling plugs very often and is blowing a crapton of thick white smoke. A sparkplug will last around a week with use most days. If I ring it out the smoke clears and it runs okay, but I'll sit at the lights and when I get the green. she hesitates and coughs out with smoke and stutters before finally going for gold. I had a compression test done and it came up a little over 180 which is far from the danger zone I think. Ive cleaned the carb to no avail and am hoping its a simple fix. Ive recently read that it may be cam seal? Maybe my oil ratio? I am a poor full time student in need of some assistance. Any would be appreciated. Cheers :bye:

you answered your own question.

you fucking auckland faggot. sam'rai jackson my ass.

Is it using oil??

[samurai jackson]

Man. What a welcome to kiwibiker. Hope everyone on here isnt as much of an asshole as you. So you must be suggesting that I constantly rape my bike at top end to stop smoke? Obviously thats not a solution and theres something wrong thats causing excessive smoke even for a 2 stroke. If your not gona say anything remotely helpful how about you go and piss someone else off.

Im not sure of the amount of oil that its using exactly but it hasnt even chewed through a full litre and ive done around 3 tanks so far. I think it should last a bit longer and the level seems about right.

Ignore him like 28+ other people do

White smoke usually means water is in the oil. Sorry dont know the bike is it water cooled??

Its water cooled. Ive checked that too. Its full and its never dropped. Think I might have to bite the bullet and take it to a bike shop for diagnosis and then repair myself to save some coin.

Not on a two stroke it doesn't

What type of two stroke oil are you using and have you checked the gearbox oil level?

Im using Castrol Activ 2T.....and the second part I have not done. Would that be the next step to eliminate possibilities?

Yes, a leaking crank seal can let transmission oil into the engine

Okay. Thanks for that. So If I have a low level than am I to assume that the seal is buggered? And would it be a job youd recommend for a specialist or is this something I can do easily with a bit of research beforehand? I consider myself fairly good at learning new bits and pieces. It helps me learn and saves $$$

I'd sooner wager $5.00 on your 2-stroke oil ratio than a cam seal on an RG.

I think he meant a crank seal

Are you just using the oil tank on the bike or are you pre mixing it?

Im using the oil tank. I know that one way to eliminate the (possible)problem is to disconnect it and start using premix but I was hoping to sell it soon and have it running well without any issues that would put people off the sale.

I would hope its only that. I will investigate more on the weekend. Is it a simple task?? I haven't actually attempted it yet. I wanted to make sure I was on the right track before I meddled with it

White smoke on two stroke sometimes suggest incorrect air intake.

Check that your float valve is not leaking, I've had this issue on a few two strokes. Then reset the float level to factory specs. Also check the rest of the carb settings are not way out from factory specs (assuming the bike isn't modified).

If you havnt already fixed it , my guess is the crank seal on the generator side. It isnt hard to replace but you need to remove the motor split the cases remove the crank then fit new seals, they (you replace both of them) cost about $100 , you should fit new O rings in the water passages $2 tops and depending on how carefull you are may or may not need to get a gasket set. There is a very well hidden bolt holding the cases together hiding behind the drive side bearing on the balance shaft. There are manuals in existence but I dont think you are likley to ever see one.

Assembly is the reverse of dissasembly so pay attention to what you are doing. Use a torque wrench
