Awesome kit, absolutely rips outta the box, and is so dang reliable. Just pick up some good quality wrist pins (that's the only thing that's killed one of mine), and install them right. Maybe snag the 16.3mm wider than stock small end bearing, its got the space for it so why not

Piston Broke at 83 miles

The three starts are tentative. At 82 miles on a new odometer, and at about 35 MPH, the skirt of the piston below the intake window broke out, was digested and blown out in fragments and aluminum oxide, and the engine stopped (luckily) only two miles from home. Amazingly, there was no scoring on cylinder walls or head. I ordered an identical replacement piston, to see if this breakage was just a fluke or bad design and quality.
Not long ago, a Treatland piston pin clip broke for no good reason, wiping out my then-new 70cc kit on a Tomos LX A35, destroying piston and cylinder...the works. Somebody needs to put a little more thought and effort into giving us only the stuff that works and holds up. I've been building, modifying, and maintaining a succession of these things for more than 60 years. This is not installation error or user abuse. If it is good stuff, I want it. If it ain't, I don't. :-)

Didn’t have the exhaust port clearance issue everyone else had. Maybe a new batch? My exhaust port was actually a bit higher than the piston at bdc and needed to be lowered.
Check my review on “puch 70cc absolute treat party supreme“ for other details.

Something's changed

I ran 2 of these kits for over 1000 miles a piece with no issue but the last two I've bought have puked wrist pin clips into the cylinder.
I've checked positioning on both, maybe they're using new wrist pin clips now?
edit treats : nothing has changed at all! if the wrist pin clips are consistently causing you issues maybe try some of the malossi or polini ones.
edit wes: Just an update on this, I knew something had to be different between the previous builds I've done and this one. I looked through my orders and it ends up I used a wider needle bearing on the piston side.
I ordered a 12 x 15 x 16.3 bearing and have been running this kit successfully for the past year. Just a heads up that the piston opening for the connecting rod is wider than stock and as such, don't use either a stock bearing or the one that comes with a crank as it'll walk, unbalance your piston and you'll be puking piston rings for days.

What size bolts for the intake?

I wanna ride! but the metric bolts I had didn't fit...
Looks like a good quality casting, and went on nice and pretty. My cali sidebleed doesn't fit perfectly but it's close.
