sthus Motorized Bicycle Bike 80cc Engine Crankcase Crank Case 8mm Studs Engine Part

Crankcase Crank Case 8mm Studs Engine Part this is not 8mm but it is 6mm but it works i like to have a 8mm case

This is a nice product for the price. The casting is about as good as anyone of the other complete motor casings that I have purchased. Just like any case they do require a lot of cleaning, deburring and porting. This Case gave me the ability to build a nice Motor out of all my good used parts! This is a good deal while they last!

FYI I had purchased two of these one after another. Didn't like a single thing about this item. I returned both of them right away, what I dislike was the poor quality of mating surfaces, looks like they missed the hole when they're drilling for the stud mounts so that mating surface was fudged up. On the 2nd in the case look like someone had dropped it on the making surface where the head goes. I didn't try a third time around.

I liked that this is the first of 3 Amazon cases that arrived with repairable damage.I very much disliked that it was advertised as 8mm studs but arrived tapped for 6mm studs.

Needs bigger threads for studs I had to retap and make them larger, other than a personal preference this case was a great purchase.

It was just what I needed. Excellent 👌

Great quality worth every penny

the threads on almost everything have craters, especially the head studs, mine all stripped out because theres barely any threads to grab, its a gamble buying this they are probably all bad, better to just but a full pk80 engine, pretty sure those are casted by runwell.
