This thing is crazy on my ‘78 pa50ii, grab a vm20 and a pipe to slap on this beast and get a nice head or mill your own .045 like I did, mad compression, mad torque, mad revs, mad wheelies man. You can’t get better then this for a cast iron jug.

Perfect on '78 NC50

Installed on my '78 Honda NC50. If you're running this kit on an Express, you will need to do some very minor trimming of the largest fins in order to get them to clear the foot pegs. Then you'll need to trim some fins to clear the transmission drain plug. Install took about an hour really taking my time. Performance is top notch, my Express is a totally different animal now. I have this kit coupled with a VM20 and MLM peoples pipe! This kit is worth every penny! ORDER NOW!!

Warning if using on Urban Express!

If you use this kit on the Urban Express, yet purchase the Urban Express head cut for this exact kit you MUST deal with the decompression port on the cylinder sleeve as the Urban Express head does not have this and you will leak oil if you align the head gasket with the hole. I ended up moving it to where the gasket covered this hole and it has slowed, but not stopped the oil leaking. I am going to have to remove this and get it properly tapped and have a recessed bolt that mounts flush installed. It is a great cylinder, but be warned if using on the Urban Express!
