Does a magnet stick to the bore of your cylinder? Vintage Bob

you have to repair the cylinder. i have run bikes with scratched cylinders BUT i prefer not to do it, just have no choice. one of them was the last race and the need for some points...
do what bob say and if it´s plated (the magnet don´t stick), have it replated.

Can you get some pics of the cylinder up? The intake port with out the reed? The magnet kinda sticks makes me wonder if you have a sleeve in there already?

from what i see i dont think i have a sleeve in it and relooking at it from the shop it has two small chips on the top side of the intake ports and one visable scratch that you can feel with your finger buy my nail dont catch it im thinking im going to hit it with a scotch pad and get a piston and run it untill i get the money or find a cheaper cylinder around
I sure would not waste a new ring in that bore. But,
Its not like the end of the world, just a few hundred bucks. In the long run the best choice. I still do not see a sleeve as an even alternative, way sub par at best.gregy133 said:
