Happy New Year to all!
My 2T has seized, & fortunately freed itself after cooling. I was doing around
50 MPH & the motor has never seemed "tight" as though running in.
I have removed the top end & the motor has clearly been re-furbished.
The LH cylinder has been running considerably hotter, (for example the inlet
manifold gasket was baked to the metal on that side) The piston has taken
the brunt of the seizure, & I have had the cylinder professionally honed as a
precaution, & the bore is perfect. The clearance between the skirt of the new
piston & bore is .0035". I have been using a 20:1 oil petrol mix. (semi
synthetic)
I have not as yet checked the timing or points gap, as I guess this could
cause the above situation ? (I will do that today).
The members on the forum have far greater knowledge than I, Is there an
inherent issue specific to the 2T engine? I was running low on fuel could this
have a bearing on the situation?
Is it best to use mineral oil as that would be the original specification?
I will need to ride as though running in, (I assume) what is the best advice
for this?
Your input, guidance & comments would be greatly valued!
Best Regards Bob
