Smoke no RPM, oily plug????

<< < (2/2)

Twist-a-grip:
Sounds like a possible wet side crank seal.  I am currently working on a bike that had both wet and dry side seals wasted.  Smoked like Keith Richard and would not rev out.  I am amazed it even ran.  It would run until the plug was so oil coated it finally wouldn't fire.  Check to see if your trans fluid has dropped any or has thinned out do to fuel dilution.  You can check the dry side easy by pulling the flywheel cover and check for gas/oil residue.

Right then... Mmmm
Well it's like this.... Last week I purchased 2 of those green plastic petrol containers from the garage filled with fuel. One I mixed with 2 stroke at 32:1 then got distracted for a couple of days. I chucked one in the tank and added 2 stroke at 32:1, only it was the premix one (This reply should be in Humour)
So there I am trying to start a 500 with a fuel ratio of about 16:1 wondering why it's such a bitch to start and smoking like a steam train.
<Que Laughter>
I've drained and cleaned everything, refilled and purged with fresh 40:1.
Tried to test it but before I could get her fired up.... Woodruff key's snapped off...AGAIN! I'm sure the premix was the problem though.
This stupid mistake nearly caused an expensive rebuild for nothing.
The embarrassment of posting this explanation is just punishment.
Thanx all for your advice and very kind offers, especially Baldrick, cheers mate.
