The piston I have is a 15mm wrist pin, did some comparing with pistons my dad has and we figure that it may be a 118 piston. Thanks

Here is what the build looks like so far, I had a BAPP 55 tooth rear sprocket and a BAPP chain tensioner I put on today. I just have the motor sitting in the frame until I can find a 123 piston for a good price, or just be able to find rings for a 118cc piston. That would save me from boring the cylinder also. My 3 bolt rims I will be getting sand blasted, and put flat tracks on the rear, instead of having these big knobby tires on the rear.

Here are some pictures of my first build H&S trike, and I recently just put on a BAPP long intake on. My other build that is going to 123cc is currently still down, still waiting for some parts, got a web 99 cam, 123cc piston and 3in vintage wheel spacers coming for it. Thanks

Looks like a PK piston that's been stroker cut to me

Thanks Mike! Sent measurements to Jwheeler hope I can find out what cc this piston is so I can get rings.

As Mike states the original designed piston had been modified to be used in a stroker crank motor. If used expect it to knock, make louder piston noise as the normal clearance is going to be larger due to shorter piston skirts. Easy enough to measure piston size, measure across bottom of piston skirt, add @ 0.004 for clearance and convert to millimeter.

Been wanting to share this with some of you for awhile, and today I could finally get a picture of it in the daylight. My father's old modified race bike, it all needs put back together. This is a fully suspended bike, This thing is very wide, wider than legal limit I was told. The motor that goes in this is a stroked 210cc 185s motor. Huge stage 2 cam, 32mm carb I believe went on it. Had a supertrapp full exhaust system and a lot of other goodies. He still has all the old parts that went on it. Packed in our several barns of parts, lol. We plan on restoring this bike someday, or get it all back togther and running again. Has been part for awhile now, ever since I can remember and I'm 17 now. Thanks!
