* Ports cleaned up and polished
* 1mm shim under barrel and 1mm shaved off the head
* Electronic ignition reset to match shim
* Simonini exhaust
* Air cleaner drilled out with a 'heart' shape hole.
With the air filter mod I had to get to a 138 main jet before it stopped running lean.
However when I run it with the original air filter I only need a 125 main jet before it runs right.
So for all those doing this air cleaner mod beware because it leans out the engine quite a bit and you must up jet.
