Hmmm, interesting...
Now I'm wondering if it's a Supreme or a Twin...
I read the Supremes have a revised motor, with a flat top piston at the front and a domed piston on the rear to raise compression in an attempt to deal with the weak rear spark.
Also, while the jets out I noticed that it's not the plastic tube type of a G4 Twin500 (I'm looking at an old blumbly thread at the moment), it's got a ring in the outside of the head AND a beveled edge on the jet head also. As far as I can tell the jet I'm looking at belongs in a 85cc motor?
