don't know if anybody here has used them or not, but after you see what i have here you may want to think twice about them. i say, stick with the kits you get from bailey's.
i picked this up from the local stihl dealer after hearing they could get them in. now, you need to realize that the cost has nothing to do with it. i wanted to try one out to form my own opinion, not save a buck. the cylinder is pretty crude (i'll be using that word alot), and so is the piston. lots of casting flash, roughness, and miss-alignment. not very pretty, but will do the job as is. it was a bolt on and go job, no cleaning up casting or ports or anything.
cylinder, exhaust:
notice how square the exhaust is? maybe a ring catcher, we'll see.
intake:
hmmmm, where's the ring land? maybe another ring catcher?
transfer:
the white area is what i call rougher than a pitted gravel road.
squish/combustion area:
how crude do they want it before they pull it off the line?
the plating looks alright except it doesn't go 'all the way up'.
the piston:
it has the same rings that come with the nwp kits from bailey's, nothing special there. they work.
you need to use the supplied clips. they are much bigger. the wrist pin was tossed. i used the original one as it fit a little tighter in the piston.
how does it run? it runs o.k., nothing stellar or mind blowing but i only have about 2 tanks of fuel through it. the compression is about 140psi, started out with 135psi. the squish is about 40thou and there isn't any room to cut the cylinder without risking freeporting.
so! keep your money and buy stock. if that isn't feesable, get a nwp kit from bailey's, they are by far the best aftermarket kits out there.
here's the saw for you perverts:
