03 blaster need help.

[pcoates48]

i have a namura piston. its stamped 6794 on the top. i need to know what size it is so i can order a new one. i think its a 67.50mm. can anybody help me. thank you...

Order a new one? What happened? You might need to bore it out if it broke... In which case you'd have your shop measure your cylinder, and then bore it out to the next size. THEN you'd buy your piston.

 

[pcoates48]

it was bored out but i dont remember what it was bored to. the cylinder is good.

The only way to find out what size that jug is by measuring it!

 

[pcoates48]

[Blaaster]

You need a presicion measuring device, the bottom for piston size, near the top to measure for wear.

you need a bore gauge.

Thats the baby, tools over here in Aussie have some strange different names, so I dont use as to not confuse.
