Sold 056 Magnum Top End (Used)

[HumBurner]

Have an 056 Magnum top end from a parts saw I bought for the carb and coil. Included are the pin, circlips, and needle bearing. Only have 3/4 cylinder bolts, but if the fourth one shows itself, it'll be included.

Some carbon but not bad. The little section I scratched off on the exhaust window came off easily. No real scoring on the cylinder. 34mm exhaust window.

Piston is in decent shape, but a few flaws. Some light carbon buildup on the edges, with the dome having a thin but solid layer. Rings seem good. Note the mark above the circlip-groove and below the lower ring-gap.



Haven't inspected the bearings in the case to see if something let loose and made the mark, but there is no corresponding mark in the cylinder I can find. Might be a factory flaw.

I have done zero cleaning to this other than blowing some of the crud off with air.

Asking $130 shipped in the 48 states.

It comes in at 55mm. Thanks for the suggestion. I neglected to update this thread with the info and pics.

55?
Um they came in 52, 54 or 56 to my knowledge. I could be wrong but it would be a first

Checked it with the calipers and it comes in at 55.

So it's either wear or the calipers being off 1mm.

Tough to say from here.
Mag2 was 56mm.
Mag was 54mm
Standard was 52

Clear the transfer port and look for more info there in raised print

If I'm not mistaken, those notched corners on the cylinder base and the fact that fins are clearanced for the exhaust pipe pretty much mean it is a 56mm cylinder. Plus, a piston measuring 55mm obviously won't ever fit into a 54mm cylinder.

Cheapy caliper is my guess. They should be more accurate than 0.5mm/0.020"

Pistons (unworn) will have 0.005+ taper towards the top. Measure at the skirt.
