and no next to nothing on two strokes never owned one . i used metal dish washer thingy and scubed and scrubed the carbon on the one piston i have cleaned up okay it got a tiny puch mark type tiny hole on the crown

Only thing cause that is heat i guess as it got no valves i chould not find any markings am assuming it under the piston the a- c stamps

i have taken engine to somone in the know and they think crank is a good one .what i wondered is isint the cylinder bores a special coating , that any reboring whould reqiure a expesive process of replating

as i dont have my glasses on i nerly fell of my chair when previous post seems indicate a web site where you chould buy some pistons from wow i been looking for over 2 years.

My ns 250 r i brought for nz $ 499 its missing all the body work the wiring is a complete mess it looks to have been raced and the auto oil injection seems been removed .frame and wheels are great brakes cyclinders even work well , i fixed up a 92 vfr 750 (crash damaged i have two 90.92 and a cbr 900rr 97 and a 80,s vt 500 the Ns 250 is a huge long shot . i seems to think i need to take the engine apart and do the main crankcase seals . as i have read where if this isnt done you can wreak a 2 stroke engine is this true.

If i pull the pin on the project alistair you can have any of the engine parts that u need eg crank

ps a few details on the ns 125 pistons

Gudgeon pin is 16mm diameter x 47mm if that helps.
