I won a pair of stock bore oem cylinders off eBay for a great price. One has had a touch of port work done. The intake has been cleaned up a lot and also has the 2 extra ports added into the intake. I don't think the transfers or exhaust has had much work though other than smoothing the castings. So my question is, would I be better off sending this one to have the porting done completely or would it be worth just running as is?

lets see pics of the exhaust from outside thru the port and inside from the top down into the cylinder.
they both should be done to see maximum gains.
is there a piston fitted to this cylinder ? does it measure the correct clearance ? and make sure all ports are chamfered correctly to prevent rings from snagging < so in that breath, unless you have definitive answers to those, send it out to a builder...... Ken Oconnor Racing of course

I've been out of the 2 stroke game for a few years now. My last one I pieced together from a rolling frame and built a motor from eBay parts and it was a runner! Was a ported 3mil by flotek. I've got a few videos on YouTube from back then. I've got a spare motor now that just needs a left side case. Might build it into another beast after I get my suspension finished
That cylinder will need freshened up. It needs measured for roundness, taper, bore diameter, etc. That's a very mild clean up, and those boysen ports that were added are very tiny. I think this cylinder has potential with more work. I would suggest getting the porting templates offered from Ken. These WORK!

good deal! yea I think when I get the chance soon, hopefully, I will be sending the cylinder out for some good all around trail port work. and also going to send the head to be rechambered. I never did that with my old blaster, so it should wake it up even more.
