Awesome! Thanks, I'll probably end up ordering that in the next year or so. I'll have to change the flange because my bike's rocking the bt80.

Also was curious if anyone had experience using these puch heads and how good the O-gaskets on these are? If they are good that would definitly be preferable over the s**tty metal gaskets the kits normally have. https://www.treatland.tv/puch-38mm-O-RING-high-compression-head-p/puch-38mm-oring-head.htm

Oh man... i forgot the old 50cc cases had literally no ramping, im amazed it revved as good as it did XD definitly gonna need to take a decent amount off the corners to smooth out ait flow x.xView attachment 184949

What does ramping mean? Never heard of that term before.

Im probably using the wrong term but basically instead of all those hard edges leading up to the transfers im gonna dremel it out so its smooth slopes like ramps at a skate park

 

[darwin]

Actually, that term makes perfect sense. Just never heard it used in that way before.

Fair enough, pretty sure i got it from one of the many FB groups for these. the 66cc cases kinda have some but i still took a lot off my last one too smooth out the airflow. I just gotta be careful with my 48cc case as there isnt as much meat there as the 66cc case.
