ok in the manual it shows reeds but i can't seem to find them. anyone have a pic of what they look lke on a 87 250? i have the head off right now my piston was toast. also how do i get the wrist pin out i took out the clips but i can't get the pin out.

[smreinert]

well i did some searching and there are no reeds on this bike it works by some vac caused by the stroke. but still need help on the wrist pin

[MX86]

take one guy and hold the piston tight. the other guy take the end of a 3/8" drive and a rubber mallet and wack away...

yeah wristpins sometimes feel like they are pressed in. haha careful wacks tho dont want to damage the rod in anyway.

that engine is a piston port engine. no reeds. i am servicing one right now. pull the circlips from the wrist pins and take a 10mm deep socket and knock the wrist pin out.

you need a special tool for the piston pin it's called a BFH. a Big F#@king Hammer...lol

well the bfg worked. it would not start when i got it i rebuilt the carb and replaced the coil any other thing that would cause it not to start? i can check while i am waiting for my new piston.

[MI_2Stroker]

depends, did it have spark? Could have been just a dirty carb. Really depends on whether or not you had spark to the plug.

[smreinert]

i had spark. just wondering if it was just the rings mashed into the side of the piston and a huge gouge inthe piston
