Hi Ray. What is the difference between the high hole and or short? Does it affect preformance? I have a pk80: would you suggest or recommend a newer piston for upgrading?
Im.wondering the aame. . It sounds like an af80 crank in a yd100 bottom end. Besides balancing that would button up the crank portion of the build then?
yes!! fits fine but you need to buy shims! RMD sells them set 5$ .25mm shims spacers! some even make them out of shim material. not sure how other then water jet though how you could cut that!
@@BuildBreakFix hi i have an AF80 and i wont to know if it will fit in 100cc engine or what it will need, i dont understand what you were saying in the previous comment, thank you.

Low hole is very low end power. Where high hole is more mid range power. (Port design) Both side by side with the correct rear sprockets can perform the same. High hole piston can be altered a bit more porting wise is why most buy it.
There is always side to side on cranks normal! Con rods will always have side to side play. Up and down it should have none! That is the one that matters!
@Build-Break-Fix Thanks for the input It just seems like there's a Is lot of side aside play Is super happy to hear that it's normal .. Do you happen to have a video to show the inside of a jug and a good piston?
Brother, I can never hear what you are saying in your videos. The volume always seems to be low even when my own device volume is turned all the way up. Can you please talk Louder. Or put the microphone closer to you. Thank you so much
@@BuildBreakFix ... Hello my friend, happy Halloween.. 🎃 I have a question.. Can a person put an engine on a Fixie bike and make it work with that tiny little fixed sprocket in the back? Will a 80cc or 100cc have enough power to pull the tiny little Fixie bike sprocket???
I just ordered a new crank for my pk80, I also had to get a high hole piston. Thank you for the knowledge and great videos
🍺😉👍

Do they make a 49mm low hole piston if they do where can i buy one
They do not.
Question how much side to side wiggle should there be on the shaft
The reason I asked is because I just took apart my 80cc motor to replace the gasket and I noticed there's lots of play on my crank shaft

I don't know why you can't hear me lol. Most people say I'm too loud 😂. I think this is the first time I got told I'm to quiet.

So the yd100 cranks won't fit the pk80 bottoms?
Nope 4mm wider
I see it as a possibility to modify the block from 50cc to 100cc
you cant because transfers are not shaped the same.
@@BuildBreakFix I want to say with a 50cc crankshaft because I see people on RUclips putting only one 80cc piston with a 50cc head
