so pretty much you have a stock ported cylinder? it looks like you had better get back in that exhaust port and smooth and polish it. doesn't look like that's gonna stay clean at all.

well it doesent look slick but it is i took some 360 sand paper and it is silck as glass
 
I don't wish to sound like a spoilsport, but I think what you have done with the porting is going to hold you back.

Top marks for giving it a go but, now get some tools and clean it up a little smoother.

It looks like you have been over productive with cleaning up where the reeds bolt on, do I detect some low spots.

Mke sure you get a good amount of sealant on there.

well i just got done sanding the exaust port and i can just about see myself i it so i think it is done
 
Throw that paper base gasket in the trash and get a stock gasket. Looks like you just cleaned it up a bit, The exhaust does look very rough in that pic , have a different one?
 
im gonna give u some advice, a dremel is the worst tool u can use to port a cylinder, if u want to do it right and get something out of it find u a pencil grinder and get some templates to follow, 1 slip of the wrist and that motor is more than likely going to end up a paperweight in ur garage.
 
Although you have to get the exhaust port so that you can see your face in the finish, you must first get the surface smooth and uniform.

The surface should be smooth with no whoops which will cause turbulence.

Likewise with the intake, all casting imperfections, steps and scratches must be removed, and the finish should be somewhat less than mirror finish, to retard the beading of the incoming fuel.

Long shaft cutting tools are a must, so that the business end can be supported close to the work area, otherwise the cutter can chatter, causing imperfections.
 
well we got it put back toghter but i f**cked up and broke a bolt in the intake while i was tighting the bolt up but after spending about 2 hours of trying to get it out it finaly cameout and if we found some bolts tomorrow hopefully we will have it running

Are you using a tension wrench?

Bolts should not break if you put them down to the correct torque settings.
 
Ill give you an "E" for effort but all i see thats been done is the casting has been roughed up.

Go on you tube and search ken oconnor racing if youre serious about porting and learning.

Personally i dont have the patience to do it and for my money by the time i invested in the time/effort/materials its easier to send it to ken but if youre serious hes the guy you need to study good luck bro!
