The return of NEL LUSSO!!! (porting)

[Jkmthor]

So my bike is naked at the moment. So far I have a coil and mag on the way, rings to order, studs to order, and a cheap but better carb to find. I have a month to work on this and wanted to look into porting my cylinder. I was hoping you guys could point me in the right direction on this one as I am clueless on what I'm doing lol

-widen the intake and exhaust close to 24mm/0.95".
-raise the exhaust height up 1-3mm.

----------
you can use only a chainsaw file if you want. but raising the exhaust 3mm is a good job for a cheap rotory tool kit. then finish it with the chainsaw file.

----------
the intake doesnt need to be as wide as i stated above. just take it easy.... stock works very well! IF you take the maximum/ the bolt on exhausts will not work! so you should decide what exhaust u like b4 you port for power.
