Stab in the dark, but you never know!
I have after a long search and wait got some nos rings for the 250, trouble is im not happy about how the top one sits, got the first set a week or so ago and upon trying to get the upper ring inside the barrel it snapped into 4 pieces (using a ring compressor)! another set came today and again im not happy about how the top sits, the lower ring sits almost flush inside the recess, what i think is how it should be, the upper protrudes more. This is for the newer SX250 nikasil lined barrel that i got with the other engine i bought so im guessing they cant be honed rings are NOS and the correct part number according to the parts list i have?
My 2 stroke knowledge is limited but growing daily so how much should the upper ring protrude!
