The port castings are rough. The intake castings are lopsided. the transfer ports are about 1mm different from each other. piston drop checks out. my rings were properly gapped. lots of material to open things up. I will be using it with the V1 Reed intake and from what I can tell the ports will be perfect for it with some mild modification. Will update when I have results

This kit is retardedly fast. Like I nearly killed myself and have a gnarly swollen knee now fast. If you do get it make sure both your brakes work and work well, like extra extra stopping power. I would say when the pipe hits it hits hard and you better hold on to your socks. Only for well seasoned riders.

where should I start... oh, ok... the ports are in the cylinder at an angle... so they don't open/close properly! that's pretty cool. let's not forget the absolutely terrible casting job. I mean piss poor, seriously. you'll need a mountain of base gaskets for the piston to even come close to clearing the exhaust port at BDC and at that point your squish will be so fucked up you'll need to deck the top of the cylinder or countersink your head. save your money and buy a polini or get creative and adapt something else. BRN is for the birds, in fact it may make a good herb garden, yeah... that's what i'll do with it. garden.
oh, and to even use it you'll have to hone it and even then your cylinder may be so out of round that it won't even be usable.
*** or maybe you'll get lucky and be blessed with one that you can actually use *** :)
looks ok
